Tree of the Month • Weeping Willow, Salix babylonica

by: Lesley Bruce Smith, ISA Certified Arborist

Weeping Willows are one of those tree species that have captured the imagination of artists down through the centuries. This is a tree native to China, yet Linnaeus named the Weeping Willow, Salix babylonica to honor the willows mentioned in the Bible. The Hebrews, exiled to Babylon:  “wept when we remembered Zion (and) we hanged our harps upon the willow in the midst thereof”.

Driving south in October the fall color was in its early stages. In Wisconsin the colors were dramatic but the Tennessee trees had time to dawdle.  However, just south of Birmingham Alabama the fall color stopped altogether and we crossed over into the land of eternal summer.

Mother Nature’s Moment

by: Lesley Bruce Smith, ISA certified arborist

All of us know that trees and plants are important for our survival. We remember our grade school science lessons about photosynthesis and the gift of clean fresh air (O2) that trees provide.  But trees quietly perform so many important functions for us that often go unappreciated and unrecognized.

Just three to four strategically located shade trees around a house can cut summer cooling costs by 30%-50%.

2015 Winter Snowfall Alert!

2015 Winter Snowfall Alert!

The significant snowfall we are experiencing can create real problems for our homes.  Ice dams that accumulate on the edge of the roof can cause water back ups that do interior damage creating the need for expensive repairs.

This can easily be prevented by getting the snow off the overhanging eaves of the roof as quickly as possible.  The ice dams form at the eaves because snow melts on the area of the roof where heat is escaping and then freezes in the cold when it gets out over the unheated eaves.

Red Oak, Quercus rubra

Lesley Bruce Smith, ISA certified arborist

The Red Oak is one of our more common and beautiful native trees in the Oak family. Although susceptible to Oak wilt, a fungal pathogen that is potentially fatal, the Red Oak species are an important part of our urban forests. I love their fall color especially. Yet they have much to commend them all through the year. They have a long history of ethnobotany, the scientific study of the relationship between the use of plants by people. The Iroquois people had an interesting use of Red Oaks for healing ruptured navels. Callus bark or the rounded healing growth that appears when a tree is wounded would be scraped off the tree. This was then dried and powdered into a fine dust and then probably made into a paste and applied to the navel to assist in healing.

In Northern Illinois the dominant species, the king of the prairie, remains the giant Burr Oak. Standing strong where most trees fail. You can see it on hill tops and out crops from Chicago to Rockford and all the way through Iowa. Burr Oak still grows down south but it becomes far less prominent, while the Red and Shingle Oak, Sweet Gum, Red Maple and of course Sycamore are the trees we notice at 60 MPH.

The Flowering Dogwood, in October, was in burgundy fall color taking over the understory. In May before the big trees foliate, when the Dogwoods and Redbuds dress the forest in white and pink lace it is wonderful to behold the Tennessee and Kentucky woods. Though it is one of the best known flowering trees in the country I’d never even seen a flowering Dogwood until I was 17, when I left Illinois.

This is one of the most common questions we get asked this time of year as arborists.  We know that the buds for next spring’s flush of new growth got formed last summer when the sun’s energy was really strong. It takes a lot of energy to push out all those lovely flowers and fresh green leaves each spring and trees are smart!  They take advantage of the sun’s energy when it’s hot.  Any branch on a tree, or an entire tree, that does not have live buds right now is obviously dead, and those that do have plump juicy buds waiting for spring’s longer warmer days, is alive.

December Wisdom from the Trees 2014

Live Oak

The Live Oak is so named because it is a tree that is native to the southern climates of the United States and is actually “evergreen”.  We encountered this tree, up close and personal, for the first time, while on our bike ride through Louisiana this fall. Often graced with the softening effects of the spanish moss that hung from its branch tips and the ferns that would grow along its massive horizontal branches, it is without question a quintessential example of enduring arboreal beauty.  While riding one day I stopped and photographed the tree shown here and paced off its size.  It has a 125 foot branch spread and its trunk was 10 feet in diameter!  It made me reflect on the fact that it was alive and probably quite large at the birth of our nation.  A conservative estimate of its age would be between 350 and 450 years old and I felt quite humbled standing below its massive canopy.

The Live Oak was used for ship building and starting in 1799 large stands of southern land covered in Live Oak were purchased by the federal government for naval purposes. The Oak, it has been said, can be compared to our dog friends in its place as man’s companion. Throughout Europe and North America the Oak has a long history of deep religious and magical significance.

It’s a funny sounding name that doesn’t really capture this tree unless, of course, you’re just looking at the flowers and fruit, which must have been what the botanist that named it was looking at.  The hardiest of all the Magnolias the flower isn’t showy, white or pink the way you’d expect.  Flowers born on the upper parts of the tree, which grows 60 to 80 feet, you generally don’t know that you are looking at a magnolia at all.  If you look real hard the fruit does look a little like a cucumber.  I recommend it as a replacement for Ash trees and it’s among the best.

Maybe you recognize the state song of Indiana

The Sycamore tree is a standout, both because of its large size and it’s mottled white bark, that earns it the names of White Tree and Lacewood Tree. The bark of the Sycamore is too rigid to split or furrow as the tree expands (which is what most other trees do). Instead, “plates” of Sycamore bark break off and fall away revealing lovely, massive, white, mottled trunks.

Apple • Malus

There is so much to say about the wonderful Apple tree, but alas, all we have time for is a brief fly over.

Apples originated between the Black and Caspian Seas.  Archeological records find dried Apples used as food in 6500 BCE during the stone age. Indeed they are so important a food source that apples and humans seem to have co-evolved, each one depending on the other for the propagation and dissemination of our respective species.  Apples were the favorite fruit of the ancient Greeks and Romans so we find reference to apples more than any other fruit in western literature.  

AppleOrchard_Arbormsith.jpg

A private Apple Orchard in Long Grove, IL“As American as apple pie?”  Actually there were no native Apples in North America only their small, tart, uncultured relative the Crabapple.  The earliest European settlers brought live trees, not seeds because only live trees would produce the large juicy apples that we love.  Remember the co-evolution I was talking about?  The earliest writings of China, Egypt and Babylon show that people understood grafting (cloning) of fruit trees.  If they had brought seeds as Johnny Appleseed did, the genetic make up of the new tree would be completely different than the parent and usually a big disappointment.

 At first  Apples didn’t produce very well in the new world because the native bees didn’t pollinate the imported Apples.  Remember the co evolution?  Only after the Europeans brought Honeybees in 1622 did the Apples consistently bear fruit.  

Arborsmith_AppleTree.jpg

John Chapman or Johnny Appleseed (1774-1845) was a Swedenborgian (as was once the author of this article), who wanted to serve God and who’s dream was for the land to produce so many Apples that no one would ever go hungry. He collected seeds from cider mills and gave them to anyone going west.  For 40 years he planted these seeds in Illinois, Indiana, Ohio and Iowa. Didn’t Johnny know, as the Babylonians did, that non grafted Apples yield fruit that is sub standard and usable only for making hard cider? Remember co-evolution? Johnny’s Apples may not have been edible but his seed spreading gave the Apple a vast genetic storehouse in this country that never would have been achieved if we only grew grafted trees. From this genetic bank Apple breeders have selected all of the delicious varieties that we enjoy today.

Apple trivia:

A medium size apple takes the energy of 50 leaves to produce, has only about 80 calories, is fat and sodium free and if you eat it with the peel it has 5 grams of the fibre pectin, as well as lots of powerful disease fighting antioxidants.  "An apple a day really does keep the doctor a way".

Americans consume about 21 pounds of Apples every year, they are the second most valuable fruit grown in the US, and one out of 4 is exported, maybe because Europeans annually eat 46 pounds of Apples.

Apples are #1 on the list of the "dirty dozen" fruits that if you are concerned about pesticides in your food you should eat organic.  This is because conventional orchards do a lot of pest control with highly toxic organophosphates that remain in the fruit in trace amounts.

Guess What’s In Flower This Month?

White Oak flowers and new spring leaves

It’s the shade trees that are flowering. What? You’ve never noticed?  You’re not alone. Many people are surprised when we tell them that their Maples, Oaks and even Pines are in flower.

The reason that we don’t see shade tree flowers is that they don’t need to be showy or fragrant to attract insect, bird or bat pollinators. What they need is something that we have plenty of in April, WIND. In addition, there are no leaves this month to inhibit the wind from doing its cross pollinating job.

White Birch Flowers

White Birch Flowers

There are some species where both male and female reside on the same tree and yet they have clever mechanisms to prevent the tree from pollenating itself. These are called monoecious, and include Alder, Birch, Beech, Oak, Hickory, Spruce, Pine, Arborvitae and many others. Unfortunately, their pollen may cause an allergic reaction.

Some tree species have the male and female flowers on different plants to insure cross pollination. They’re called dioecious and include, Maples, Ash, Poplar, Willow, Yew, and Juniper. If you are allergy sensitive you want to promote the female of these species, which are the ones that bear fruit, and avoid the male plants because their pollen is more numerous, lighter and tends to cause more allergic reactions.

Norway Maple flowers and new spring leaves

Norway Maple flowers and new spring leaves

It is a curious and sad fact that with the purpose of eliminating messy berries, pods or seeds, landscape committees and tree planning commissions have unwittingly mandated the planting of those male, dioecious trees which are the worst allergy producing trees.

So why is cross pollination so important? Cross pollination creates genetic variation so that trees have a variety of resistance to diseases, insects and adaptability to changing climatic conditions. Trees, like people, have survived down through the ages because of genetic variation. So even though it causes a reaction for allergy sufferers, cross pollination is a very good thing.

Silver Poplar Flowers

Did you know that most of our municipal street trees are cloned? That means that they are all exactly genetically identical. This is kind of scary. Trees, plants, and animals have survived because they’ve had a variety of strategies to deal with the many challenges faced in their long history. Tree cloning shrinks and drastically reduces a tree’s ability to survive in a changing world. It is important to note that there is a direct connection between over planting one species and epidemics like Dutch Elm Disease, and Emerald Ash Borer.

Weeping Willow flowers

So what survival lessons can we learn from the trees and their wind flowers?

  • The most obvious lesson is that plants have survived because of diversity. When we select a tree for our home landscape or street-scape, plant something different than the trees that we are familiar with. Check Arborsmith’s list of replacement trees on our website.
  • Use native plants whenever possible to promote diversification and health.
  • If you are an allergy sufferer, request a female tree when planting a new replacement.
  • This spring, look for the tiny but beautiful flowers that are the evidence of millions of years of tree survival.

The Power of the Organic Landscape

Gil & Lesley with Jeanne & Verd Nolan

Last weekend, Gil and I co-taught a new class with Jeanne and Verd Nolan of the Organic Gardener at the Chalet Nursery for their spring lecture series, titled The Power of the Organic Landscape Garden.  It was a spectacular success so I thought I would share some of the juicy bits with all of you!  There is a lot of confusion about what it means to be organic. The US Department of Agriculture actually certifies food growers to carry the label “organic”  which means they have gone through a pretty rigorous process to prove their production meets a strict set of guidelines (you can read all about it here: http://www.ams.usda.gov/AMSv1.0/nop.

StrongHealthyPlants_LesleyBruceSmith.jpg

Strong plants are healthy plants, our goal is to keep plants strong.So few of our landscapes would ever qualify as organic, but that doesn’t mean we can’t make a difference!  Everyone in midwest America lives in the Mississippi River watershed.  What that means is, that what we do here matters pretty much everywhere on the globe, because our water all ends up in the Atlantic Ocean!  When it comes to growing our fruits and veggies, organic is the best way to go, but when it comes to our ornamental landscapes we need to work towards as much of an earth friendly environment as we can.  Things we can do that can make a big difference towards making our landscapes as earth friendly as possible include:

SpringFlowers_LesleyBruceSmith.jpg
  • Mulching under our trees to preserve water, nutrients and provide great root growing environments
  • Mulching under our trees also saves time mowing the lawn which preserves the use of fossil fuels, reducing pollution, in addition to eliminating the need for the use of many artificial fertilizers or pesticides because it increases the tree’s natural ability to fight off invading insects and diseases.
  • Trimming using horticulturally sound techniques, the only ones Arborsmith uses ;-), to prevent the creation of disease and ill health.
  • Eliminate the use of pesticides and herbicides on our lawns.  There are lots of ways to tackle the weed problems in our lawns without the use of herbicides but maybe the most important one is to remember that perfectly dandelion and clover free lawns are not normal natural or healthy and those “weed” flowers are great honeybee and butterfly oasis food.
  • Compost our vegetable matter from the kitchen and our green waste from the yard.

There is so much more to say but if you would like an evaluation of your property to move towards a more earth friendly landscape check out the Conserve Lake County Conservation@home program or give your earth friendly Arborsmiths a call.  We would love to consult with you on how to save your little corner of the world and make it a more healthy place for us all.

A Betula papyrifera, Paper Birch located in Northern Door County, WI on the edge of a meadow.The Birch tree is a favorite among North American trees. It likes the colder and more moderate temperatures along the northern shores of the Great Lakes. The English language is filled with poems referencing birch trees, I am sure because their distinctive powdery smooth pale colored bark make them a standout in the forest and the landscape. Even in their favorite environment, Birch trees do not live very long, only about 80 years, and are pioneer species. This means they are the first ones to establish themselves into areas of land that have yet to create forest, like the once newly glaciated plains of the midwest, or freshly burned prairies of the central states. Birch trees find their homes on the edges, the edges between prairie and forests, the edges of water, the edges of short lived (grasses) and long lived (forest) species, the edges of light.

LesleyBruceSmithWhiteBirch.jpg

Their Sanskrit name, bhrag, meant shining and I am sure it is because these distinctive species are full of light.A Betula papyrifera, Paper Birch or Canoe Birch located in N. Door County, WI in summer on the edge of a meadow. They have airy crowns that dapple the sunshine on their light colored bark with beautiful artistry. That light colored bark contains a substance known as betulin, a crystalline substance making it pale as well as waterproof. President Thomas Jefferson wrote to Meriwether Lewis recommending that he use birch bark paper for his field notes as it was “less liable to injury from damp than common paper”. However, birch trees have been serving humans long before writing. The buds and sap and even the bark could be eaten, and early New Englanders fermented birch sap for beer. They have been used to make shelter, clothing, cooking and eating utensils, dolls, baby cradles, and of course, because of the waterproof nature of the bark, the beautiful canoe. Longfellow has immortalized this in his epic poem Song of Hiawatha:

A White Birch along the shore of Northern Lake Michigan in January against an electric blue sky.“Give me of your bark, O Birch-tree!

    .................

I a light canoe will build me Lay aside your cloak, O Birch Tree! Lay aside your white-skin wrapper!

    ..................

And the tree with all its branches

LesleyBruceSmithRiverbirch.jpg

Rustled in the breeze of morning,

Saying with a sigh of patience,

‘Take my cloak, O Hiawatha!’”

Their are many kinds of Betula species including the Yellow, Silver, Downy, Water, Asian, and one of our Chicago hardy favorites, the River. The Birches have a long history of use and association with sacred rites and ceremonies, as their “light” makes them somewhat magical, mysterious and extremely well loved.

“One could do worse than be a swinger of birches” wrote Robert Frost.  As swingers of Birches, we agree.

The White Birch’s cousin, the Riverbirch is a favorite of ours because it is hardy in the Chicago area and has a beautiful cinnamon colored exfoliating bark that gives interest all year long. After this winter, any plant that can look good in the winter gets extra points. Read more about it in September 2012 tree of the month.

Ojibwa woman gathering Maple sap for sugaring.  

Ojibwa-woman-father-maple-syrup.jpg

photo credit from: http://firstpeoples.org/wp/maple-syrup-threatened-by-climate-change/The celebration is a month later this year than last but it is finally here.  When the daytime temperature is in the 40s and at night it descends into the 20’s a uniquely American festival begins, lasting a month or more. Some of the Native Americans who first celebrated it, called it Sugar Moon Festival during which they did a Maple Dance, you guessed it, it’s Maple Sugaring time.  

Maple Sugaring is not an European import. The Algonquin people cut a “v” shape into Maple trunks and used a reed to drain the sap into wooden tree trunk buckets. They showed the Europeans how to concentrate the sugars by putting hot stones into the sap to boil off the water or by letting the sap freeze and removing the ice.

The chemistry behind this phenomena is not completely understood but here is my version. In the summer, the tree converts the sun’s energy into sugar and stores it in the trunk and roots, as a starch.  In late winter the tree converts the starch back to usable sugar. The higher concentration of sugar inside the tree creates osmotic pressure, pulling water from the soil and pushing it throughout the tree.

LesleyBruceSmithSugarMaples.jpeg

"Sugar Bush" is the term used for a high concentration of Sugar Maples.  

Sugar Bush at the Ryerson Conservation Area, Riverwoods, ILThe tree uses this sugar energy to grow or respire and like people the tree gives off carbon dioxide when it respires.  I’ll bet you thought trees only breathed in carbon dioxide and breathed out oxygen. You’re right, when a tree is photosynthesizing it uses carbon dioxide and gives off oxygen. However, at night when there is no sun, the tree is also using oxygen and giving off carbon dioxide.  

What we have then, is carbonated sap, much like a carbonated drink, when the temperature rises this time of year it forms bubbles that create pressure which drives the sap up into the tree tops and out any cuts or holes in the sapwood, which is just below the bark. When it cools at night the carbon bubbles shrink, creating more vacuum that pulls water from the soil.  This wonderful process only happens in late winter when the temperature goes just below and just above freezing.

ArborsmithMapleSyrup.jpeg

Here are a few other fun facts about Maple sugaring. If it is done responsibly it doesn’t hurt the tree because it uses only about 7% of the sap.  Each year an average Sugar Maple will produce 17 gallons of sap and it takes about 40 gallons of sap to make one gallon of Maple syrup. Maple Syrup is regulated and has to contain 66% sugar. It also contains natural phenols and anti-oxidants and 300 different flavor compounds that make it unique and not duplicatable. There are many imitations that contain mostly corn syrup and which the Quebecois refer to as “syrup de poteau”  or syrup tapped from telephone poles.  Abolitionists used only Maple Sugar because slaves were used to make cane sugar.

So the next time you have pancakes with real Maple Syrup you will have a story to tell about the sweet gift of the trees and the American Indians. 

The Buzz on Bees

Mother Nature's Moment

LesleyBruceSmithBees.jpg

Bees on newly installed sugar in feeder tray, excited to get some extra energy before the next polar blastIt has been a tough winter for all of us, especially for the honey bees.  I am so grateful for my bee mentor, Larry Studer, who came over in January, (yes January!) and helped me check into my two hives.  I was worried about one of them because I did not hear any activity in the hive.  Sadly, we discovered my strongest hive had died of starvation;(.  Not because they did not have enough food stores/honey, but because the temperatures had been so cold for so many consecutive days they could not move around enough to access the honey they had. It was a grievous thing to open the hive and find the cluster of bees all dead and frozen.  This is a year for the stout of heart, both bees and beekeepers.

ArborsmithWeather.jpg

With Larry’s wise help we transferred the extra honey stores in the failed hive to my hive that was still thriving.  This was a hive we had established late in the summer 2013 with a new nucleus (nuc), which is comprised of several (6-8) frames filled with honey and laden with honeybees and their queen.  At that time, we also added bees and honey from my existing stronger hive which was absolutely packed with both.  In this way we were able to get the new hive off to a strong start.  It is still a mystery and a wonder to me how those wise little honeybees sort it all out. I did not harvest any honey last year in an effort to keep my hives healthy and strong.  During this winter I was very glad for that decision.  

LesleyBruceSmithFrozenBeeHive.jpg
LesleyBruceSmithBeeHive.jpg

Opening the live hive in January to discover a very healthy colony! The bees don’t ever sleep.When Larry came in January, because of my concern, he did something I would have never had the courage to do on my own, as a novice beekeeper.  He opened the hive on a 20F day when the snow was falling, to see what was going on and to install some feeder trays with clumped sugar he had prepared before hand to provide supplemental food. What a sad thing to open the hive and find the once vibrant cluster of bees all frozen and dead. This was just before the second polar vortex creeped down from the fridged north.

LesleyBruceSmithBee.jpg

Beginning the transfer of honey stores to the living hive on the left from the dead hive on the right. The “dirt” on the snow are the bees from the frozen hive.After thoughtfully inspecting the hive colony we set to work to carefully move the remaining honey stores into the still active hive.  We placed the honey stores as close to the live cluster as we could manage without hurting them.  They were feisty, even in the cold, and managed to sting Larry several times.  I was stung a few weeks later, on another just below freezing day, while adding additional sugar to their stores.  As smart as they are, I wish those girls understood I was their friend, not a foe.  I am happy to report that as of mid-March, they are active and healthy and I am praying we can get them into the real spring weather, surviving until their natural flower food supplies are in full swing.  Won’t that be a welcome time for us all!

American Beech Tree • Fagus grandiflora

AmericanBeechTreeW.jpg

American Beech Tree, Fagus grandiflora • by Lesley Bruce SmithIt is hard not to sing the praises of the magnificent American Beech, Fagus grandiflora.  It has such an imposing presence and the smooth silver grey bark make it easily recognizable.  The winter photo shows the distinctive “needle like” reddish brown buds that were once used as toothpicks. The coppery leaves that often persist into the winter months make it a favorite in the northern climate because it affords four seasons of beauty and interest.  The name Beech is similar to book in many languages, in Anglo-Saxon the “tree” was boc and bec meant “book” and indeed slabs of Beech bark were used in early times to write on and were sometimes tied together to create the earliest books.  The Latin term Fagus comes from the Greek, phagein which means “to eat”.  Most likely, because Beechnuts, although small, are nourishing for humans and livestock.  The Iroqouis aboriginal peoples would combine equal volumes of leaves from both the Beech and Linden trees and steam them to create a poultice that was used to treat burns.

BeechTree2W.jpg

Beech trees need to be carefully placed in the Chicago area if they are to survive and thrive.  They demand a loose, well drained soil.  This fact is only affirmed as we see Beech trees growing easily in the sandy well drained soils that are so abundant on the opposite side of Lake Michigan less than a hundred miles away.  The weather is certainly not the limiting factor here.  The heavy clay glaciated soils of the northeastern corner of Illinois are not friendly to the magnificent Beech trees we see growing like weeds in the soils of western Michigan and Door County, Wisconsin where the soils are loose, gravelly, sandy and extremely well drained, yet with plenty of moisture.  They also need lots of room, because they will dominate the space provided for them with their magnificent spreading canopy.

These are all fascinating facts about the Beech tree, but like most of our landscape plants, which have a rich history in ethnobotany, we plant the Beech because of it’s amazing structure and beauty.

A silver lining to the cold winter?  Have emerald Ash Borers been killed by cold temperatures?

Backyard Wisdom by Gilbert A Smith 

ISA Certified Master Arborist

EmeraldAshBorersW.jpg

There has been a lot of press recently, about tests done in Minnesota indicating that the cold weather may have killed large numbers of the Emerald Ash Borer.  This is very good news in the battle against the borer that is killing our Ash trees.  So what can we expect to see next summer?  Are the Ash going to survive after all?

Autumn Ash Tree • photos by Lesley Bruce SmithI’m very sorry to say it, but the answer seems to be, in the long run, no. The state of Michigan lost hundreds of thousands of Ash trees in spite of cold blasts.  Tests from Canada indicate that the borer has coping mechanisms for cold.  If the polar vortex had occurred earlier in the year when the insects had not yet acclimated to the cold it may have killed more borers.  Like us, the borers get hardier as the cold persists, but it is the big fluctuations between warmer sunny winter days and arctic blasts that are killing.

In the long run however, because there is no natural population control for the Emerald Ash Borer, their numbers will skyrocket. They multiply by a factor of 10 every year. This means that even if all but one single mating pair were killed, in six years this couple would produce one million of their kind.  To complicate matters they do their dirty work under the cover of the bark.  By the time we can see them, their populations have often built up so high that too much damage has been done to save the tree.

Really if the reports are accurate, and the borer populations have been knocked back, this is good news because nature is giving us a second chance. When the first wave of attack came to our area many tree owners didn’t act to protect their Ash trees until the infestation was out of control. Don’t wait!  If you haven’t already, ask your favorite Arborsmith to inspect your landscape to see if you have any Ash trees.  The cold may have given us “a time out” in which we can select a few Ash trees and protect them. In 5 years we may not have another chance.

January Wisdom from the Trees 2014

Tree of the Month

American Elm • Ulmus americana

AmericanElm.jpg

American Elm, Ulmus americana; by Lesley Bruce SmithIt seems a fitting photograph of this month’s highlighted tree to be taken on a late winter day.  The embattled American Elm (Ulmus americana) was one of America’s best loved and most widely planted species.  Foot traffic, pollution, concrete and even nearby building construction could not knock out this rugged urban champion that can handle all kinds of human abuse. Unfortunately, what we humans failed to do directly, a little beetle from Holland managed with little difficulty.  That is why so many cities were denuded of their urban forests when hit by the fungal organism of Dutch Elm Disease. The beetle arrived in a shipment of furniture from Dutch country which was transferred from ship to train in New York and traveled west.  We can trace the spread of the disease (which is not a problem for the European Elms who co-evolved with the fungus) all along the iron rails across America.  It was transmitted on the the tiny feet of the beetles that escaped the train all along the route.  However, in spite of all the struggles we have endured with this species, it is not hard to see why it is a favorite, with its spectacular cathedral like arching branch structure that so elegantly graced many American boulevards in the last century.  

The American Elm is a native of North America, as her name suggests.  The bark tissue was used in combination with the Slippery Elm (Ulmus rubra) by the Cayuga aboriginal peoples in the child birthing process to prevent inflammation and soothe torn membranous tissue.  

The lesson this month’s tree has for us is that species diversification in our urban forests is a must, yet  it is a lesson slowly learned as we continue to plant too many of the same species, creating the set up for another catastrophic loss.  For Elm lovers in the present, much research has been done in cultivating disease resistant varieties of American Elm, many of which were created right here in Illinois at the Morton Arboretum by Dr. George Ware.

Does the snow harm my trees?

Being a “wet blanket” is a good thing.

Backyard Wisdom by Gilbert A Smith 

ISA Certified Master Arborist

BackyardWisdom.jpg

Snow cover early in the winter is very good for your trees and shrubs.  It acts as a wet blanket for your trees, insulating the soil from freezing, while slowly melting and watering roots. This allows a whole riot of activities that are essential to tree health.  If we don’t have snow cover, it’s even more important to leave the natural leaf litter beneath the tree canopy, because leaf mulch, like the snow is an insulating blanket that keeps the soil warm and biologically active. (click here to see Mulching Abstract)

So what is going on beneath the snow white cover?  You’ll be shocked to know that there is a mating dance happening between tree roots and fungi in the soil.  The fungi need sugar for food to survive and the trees have those sugars stored in the roots.  The Fungi have nutrients that the trees need, like nitrogen, phosphorus, potassium and other micronutrients.

Those tricky tree roots actually lure the fungus by secreting a sugar rich syrup like perfume that attracts the fungus.  “Come and get me fungus!”  The fungus falls head over heals for the tree root and penetrates and infects the root cells.  Then the fungus wraps its arms, called fungal hyphae, all around the root.  The two actually begin to grow together so closely that you can’t tell where the tree root begins and the fungal hyphae end.  That’s why we call it mycorrhizae.  mykos=fungus  riza=roots.  Literally fungus-roots. Naturally, when Arborsmith fertilizes your trees we use beneficial Mycorrhizal fungi.

The tree allows the fungus to have some of its sugar in exchange for nitrogen, phosphorus and potassium which are essential to tree growth.  Another benefit of the association is that the fungal hyphae greatly extend the surface area of the root, making it much more effective at harvesting nutrients and water.  The root is so pleased with this new source of minerals that it doesn’t need to grow as long, allowing the fungus to branch out and harvest for it.  That smart tree root has given up just a little sugar, gained the nutrients it needed, got access to more water and saved energy in the exchange by not having to extend itself out so far.

Not far under the snow there are also a whole host of soil microbes, bacteria, virus, fungus, wiggly worms, and bugs that you can’t see that are digesting the leaves and twigs on the forest floor, living, dying and creating food for the spring growth spurt.   Things are never as quiet as you might think under the snow in your back yard.  

In February the sap begins to rise and guess what that means?

Stay tuned for Maple sugaring time. 

How do you tell if a tree or shrub branch is alive or dead in the snow and cold of winter?

Eastern White Pine • Pinus strobus

Another favorite for use as a Christmas tree

by Lesley Bruce Smith

ISA Certified Arborist

TreeOfTheMonthW.jpg

Eastern White Pine by Lesley Bruce SmithPines, in general, are a favorite tree to use for Christmas trees and Eastern White Pine, in particular, is one of our favorite species of Pine to plant for ornamental purposes in the Chicago area.  It was also depicted as a symbol on the first Revolutionary War flag and thousands of 200 foot tall Eastern White Pines were felled and used as ship masts for the British Navy.  To the indignation of the American colonists, the crown claimed the tallest trees and any settler caught using them might have all his land confiscated.  However, it should be noted that no pine species is actually native to the northeast corner of Illinois.  All the pine species capture our imagination and so we plant with abandon.  Recognizing that pines are out of their comfort zone, however, helps us to understand that we need to treat them with a bit more care and tender loving.  Eastern White Pines are no exception to this rule.  They need to be planted out of the clay soil in northeastern Illinois, up high, in a well mulched organic soil environment where they respond best to being permitted to self mulching of their needles and cones.  They are tough only when they live in well drained environments.

I love many traits of the Eastern White Pine including it’s lovely soft needles and gentle yet potentially towering presence in the landscape.  Hands down my favorite attribute of the Eastern Whites is the lovely sound that the wind makes through its branches.  We purposely planted them outside our bedroom windows to help lull us to sleep.  

TreeOfTheMonth2W.jpg

Pines have a wonderful history of being a living pharmacopoeia. Pines in their native habitats exist in some of the most extreme conditions on the globe, including drought, heat and elevation.  Similar to other medicinal herbs, the naturally stressed, super tough survivors will have a greater medicinal value, possibly due to the higher levels of isomers and anti-oxidants produced by them.  Pines are the source for many essential oils and the use of the Pine knot goes back to the Romans who used them as torches that they knew had both antiseptic and antibiotic properties while burning.  The Cayuga peoples used the Pine knots in the treatment of tuberculosis, creating a tincture from carefully selected knots and utilizing the antibiotic, pinosylvin carried within the pith tissue.

Probably the most popular use for Pines is in the treatment of respiratory ailments.  They release terpenes which have expectorant, antitussive and anti-inflammatory properties. It has been suggested by some that every hospital should have a Pine grove on its grounds where the healing properties of these magnificent plants could be fully utilized.1

What Does Maple Syrup and Anti-freeze Have in Common? OR

Why don’t trees freeze in the winter?

Backyard Wisdom by Gilbert A Smith 

ISA Certified Master Arborist

MapleSyrup.jpg

This is not an easy question to answer because though it has been studied a great deal, plant scientists still don’t completely understand the mechanisms that allow trees to survive in the cold.  When trees go dormant they don’t really stop growing.  They continue to function including photosynthesis, (yes, even without their leaves) they just slow way down. Living plant cells never stop creating sugars, using energy, building, transporting, and protecting their system.  Most of the cell is water. When water freezes it crystalizes and expands and would rupture the cell walls, killing them.  Still, trees in the Boreal Forests can survive in temperatures as low as -76℉.

BackyardWisdomW.jpg

Winter Oak Tree by Lesley Bruce SmithThe vast majority of cells in trees are dead.  Yes, that’s right!  The “inside” of temperate climate trees, the xylem, consists of dead cells penetrated with a few living cells, called ray cells, which use this dead heartwood for storage, structure and transport.  The only 100% living cells are in the cambium, a thin layer just a few cells thick, just beneath the bark.

 The tree protects itself against freezing by:

  1.  Closing down the “breathing tubes”  stomates and lenticils in the needles and stems.
  2.  Sending water into the already dead xylem structure where it can’t do any damage.
  3. The living cells partially dehydrate, sending some of their water into the areas between the cells.
  4. Life still needs some water to keep living. When they dehydrate, those extremely smart tree cells have increased their concentration of sugars, and like antifreeze, those sugars lower the freezing point of the H2O.
  5. The final protection that the trees utilize is impossible for scientists to replicate because they kill the living cells. So when it freezes outside this thick cellular soup does not crystalize or expand so the living cell wall is not damaged, thus saving the tree.  
FrostCrackOnAMapleTree.jpg

Frost Crack on Maple Tree by Lesley Bruce SmithTrees are amazing survivors!  If the temperature swings rapidly between hot and cold as it does in late or early frosts, tree cells rupture and can die, killing all or part of the tree.  An example of this which we see in forests and in landscapes is frost cracks.  Usually on the south side of the tree the winter sun heats thin barked trees, like Maples, during the day.  When the temperature plummets at night the bark splits and remains a weak spot that opens up every winter.  

We can’t manage the weather but here are some things we can do to mitigate freeze damage.

  1. Keep needles and leaves below tree and shrub branches as these  are natural insulators.  
  2.  Plant freeze sensitive plants, like Magnolias, Japanese Maples, Rhododendrons on the North side of structures so they are not “heated up” by the southern or western sun in the winter and then super cooled at night.
  3. Keep evergreens further away from the house and drives, especially near glass or on South and West exposures.  Again, the building or drive heats and or reflects the solar radiation in the winter causing the plants to heat up and lose their cold hardiness.

Think of your trees on a cold winter day, because your trees always appreciate your thoughts, and know that your trees are prepared for the freezing cold weather.

Douglas Fir by Lesley Bruce SmithBecause Gil’s article on Trees and Freezing and my tree of the month article on Eastern White Pines are both a bit long winded  (we try to hold these posts to brief informative articles) I am going to just reference the helpful information from last year’s Mother Nature’s Moment December entries for those of you that wish to read more.

Just a reminder that using a real, cut Christmas tree is in fact an environmentally sound thing to do.  Christmas trees are a totally renewable resource and the trees harvested each year end are replaced 3 fold with young saplings in the spring.  Click here to see article from December 2012 Newsletter, Wisdom from the Trees dedicated to live/cut Christmas trees.

Shagbark Hickory, Carya ovata

by Lesley Bruce Smith

ISA Certified Arborist

ShagbarkHickoryTree.jpg

Shagbark Hickory Tree by Lesley Bruce SmithShagbark Hickory is one of the easier species to identify because its name says it all.

The shaggy exfoliating buttery grey bark is so distinctive any season of the year, it is a standout, even for the novice tree lover.

Carya ovata or Shagbark Hickory is a significant member of the Carya family and is a gift to us in many ways.  Few of us have not enjoyed the savory scent of hickory smoked barbecue on a summer’s eve or relished the flavor of one of the Shagbark’s close relatives: the pecan (Carya illinoensis), in pie, or butter pecan ice cream (yummy). The Hickories produce some of the most delectable nuts in the world and every single hickory can be grown from its nut.  Each crop of nuts is unique to the species of Hickory and in some measure to the season’s growing condition; very much like each season of grapes vary in the making of fine wine. The Cayuga Tribe used either the Kingnut or the Shagbark Hickory in remedies for arthritis and intestinal worms.  A healthy high protein food, not unlike tofu, was also made from the nuts of the Shagbark Hickory by creating a nut cream using a hot water separation technique. 

Hickories.jpg

The Shagbark Hickory is one of the partners to Oaks in the northern Illinois climax forest ecosystems. Needless to say, they are a favorite of the squirrels, and trees that feed the squirrels help to expand the forest. The squirrels sense of smell permit them to discard diseased nuts and only bury=plant the healthy ones. Due to their ability to increase forest size and territory, with an increase in the squirrel population we will see an increase of other wildlife, including birds. There is even one species of butterfly which uses the Hickory as a host and is entirely dependent on it for life.

Our favorite and lifelong use of the Shagbark Hickory is in our backyard grill.  Just a very small piece (1” x 2”) of bark, readily available on the forest floor around any Shagbark, creates a savory flavor to any meat on the grill and even turns a gas grill into a more BBQ flavor.  Three cheers for the Hickories...yum yum yum!

The story continues.

SugarMapleseedlingsW.jpg

Sugar Maple seedlings germinated in northern Wisconsin soilIn September Wisdom from the Trees we talked about the soil history of Illinois.  So who cares?  Isn’t dirt dirt.  Don’t all trees grow well in dirt?

When the European settlers arrived in Northern Illinois many of the Oaks alive today were just saplings, however, there were no native evergreens.  Even today when your Austrian Pine drops thousands of seeds in your yard not one of them will germinate.  The same is the case for White Pine, Scotts Pine,  Birch, Beech, Sugar Maple, Arborvitae, Spruce, Fir and many others.   Those little seeds have wisdom that they will not thrive in this environment.  It is not the climate but the soil that tells them not to bother sprouting.

ArborvitaeGerminatedOnaRockW.jpg

Arborvitae germinated on a rock on the northern shores of Lake Michigan The Prarie soil is too alkaline and too dense to support optimum tree root growth.  If we plant these non-native trees they may live for many years but they will not thrive and they will constantly be under stress.   Of course we love our Flowering Dogwood, Blue Spruce, and White Birch.  But we have to realize that we are inviting them into a harsh soil environment that they would not choose to live in.  They need special treatment.

Here is what the trees are telling us:

  1. Our roots can not expand in the heavy clay, poorly drained, alkaline soils of the prairie.   
  2. Please provide space for our roots near the surface by mulching them out to the branch spread separating us from the lawn. (As is done at the Chicago Botanic Garden and the Morton Arboretum) (see our Mulching Abstract)  
  3. During drought we need to be watered infrequently (no more than once a week) but  heavily .   According to the University of Illinois, sprinkling systems that go on every other day do more harm than good, both to trees and to lawns. (see Watering Abstract)
  4. Please plant us at least 8 inches higher than the surrounding soil surface and give us mulch or compost to grow above the clay.  (see Planting Abstract)
  5. Don’t add soil, burying our roots.
  6. Avoid trenching, even shallow 4 inch deep trenching under our tree canopy. Lighting or sprinkler trenches can be catastrophic for us.
  7.  When planting in the confused soils near buildings avoid using those of us who are sensitive to alkaline soils such as; Pin Oak, Red Maple, River Birch, Rhododendron.
  8. Have us annually inspected by our favorite Certified Arborist who loves us and will help us thrive in our difficult circumstances.

Understanding our unique Illinois soil history helps us nurture our beautiful Illinois trees.

The Greatest Fertilizer on Earth

Mother Nature's Moment

by Lesley Bruce Smith ISA Certified Arborist

FallLeavesW.jpg

Hybrid Maple in fall color by Lesley Bruce SmithJust available in an all new format is a fertilizer for trees that we just cannot keep to ourselves!  A fertilizer, yes, but really so much more!  It is packed with nitrogen, phosphorous and potassium.  It is a root insulator that keeps roots protected from excessive heat in the summer and excessive cold in the winter.  It is loaded with micro-nutrients, it has all kinds of micro-flora and fauna, it conserves moisture and acts as a mulch and amazingly it is completely renewable, organic and even beautiful.  However, the most astonishing reality about this fertilizer is that it is absolutely FREE, yet every fall it is tossed away as though it was worthless, or even worse, a nuisance.

What is this amazing fertilizer?

The leaves that blanket our lawns each fall. Recently, in speaking with a friend we were reminded once again that many of us don’t know the wealth of resources that lay just at our feet every autumn.  By separating lawns from grass using even small mulched or planting beds we have the marvelous reward of never having to rake our leaves.  In 32 years of home ownership we have never raked leaves.  We have a mulching mower, which most lawn mowers are now, and what doesn’t fall into our planting beds to be recycled gets munched by the mower and composted into the lawn, fertilizing and enriching that area of the landscape.  So if you are panicking about not getting the leaves raked up or hate that particular chore, take a break!  Do a favor to your trees and shrubs by leaving the leaves alone.  

FallLeaves2.jpg

The Greatest Fertilizer by Lesley Bruce SmithLawn specialists will often say the lawn can’t take it, but our little acre of the world has a happy coexistence with trees and turf by just a little degree of separation.  We have a lovely lawn which lives quite happily with five White Oaks on our property, a Riverbirch, a Catsura, a Hackberry, several fruit trees, three Crabtrees and a Native Hawthorne plus lots of Pine and Spruce trees as well as many shrubs and can I just say it again, we have never raked leaves or paid to apply supplemental fertilizer.  If you need help giving up the habit of leaf raking give us a call, we would be thrilled to help you kick the habit and your trees will love you for it!

A Story of Illinois Soil by Gilbert A Smith 

ISA Certified Master Arborist

Fall Colors by Gilbert A SmithWhy is it that Illinois is called “The Prairie State” ?    Why is our climax forest ‘Oak/Hickory‘ when just 50 miles east in Michigan the climax forest is ‘Beech/Maple’ and why do most of our trees grow 30% shorter than they do almost everywhere else: North, South, East, or West?  Many texts say that our harsh climate inhibits the growth of many trees, (USDA zone map) but you are hearing it here first, THE REAL REASON IS THE SOIL.
