The Sun is Finally Shining

Backyard Wisdom

by: ISA Master Arborist:  Gilbert A Smith

You may not have liked the weather we’ve had this spring/early summer, the wettest June in Chicago area history. I did not enjoy it either, but your trees love moist cool weather. Have you noticed how verdant they look this year? Trees, even in stressed locations, like in your parkway or parking lots show a good healthy green. Stress related problems like Euonymus Scale or Apple Tree Borer are significantly reduced. This is because trees are getting plenty of moisture with none of the heat stresses. So they take advantage by over producing leaves to harvest as much sunshine as possible.  When it heats up the trees will dump some leaves. Don't be alarmed. The tree is just balancing itself out dumping lower food producers and bracing for the heat.
