Q: Why are my Aspen trees getting a fungus and what are my treatment options?
A: Since we had such a mild winter last year, a lot of fungus and pests survived the cold. The aspen trees this year seemed to suffer the most, although many plants were affected. The long dry spell we had in early summer also weakened the tree's defenses.
The best thing to do is clean the leaves once they fall and dispose of them. This will lessen the chance of eggs and spores at the base of your tree.
Next, contact a tree company and talk about treatment options with them, or if you prefer to treat it yourself, take a few leaves to a local nursery and ask them what kind of fungicide would be best to use.
Stay warm and send us any questions you have!
