July 2, 2013 • Plant Health Care ALERT!
The extended cool temperatures (ranging from 50°F to 60°F) and wet and rainy conditions that are and have been prevalent throughout our spring season are going to create abundant fungal disease symptoms this summer.
By clicking on the names of the diseases below you can get to our abstracts that explain these diseases in detail.
• Anthracnose, seen predominantly on both Ashes and Oaks

Even those who have had preventative treatments will most likely see symptoms in lesser degrees. This will be most evident with the Crabs and Hawthorns and it may be alarming to see leaves yellowing and falling early but what we focus on are the leaves still on the tree. We are trying to prevent damaging loss of leaves with these fungal diseases and because of the mild weather the trees have put out a huge crop of leaves and so even though they are losing some they have plenty to remain healthy. The record setting rains have made elimination of these fungal diseases impossible this year.
As always, if you have any additional questions on these
please do not hesitate to contact us,
Yours for healthy trees,
Gilbert, Lesley and the Arborsmith Staff
