My leaves are dropping! We’ve been getting a lot of calls this week about trees dropping leaves. Some had anthracnose disease early in the season and those leaves are now falling. The drought, heat, and high humidity have also contributed to a lot of leaf drop on crabapples, river birches, and several other species. Leaf drop is a tree’s way of conserving water. As leaves synthesize, they open their stomates, causing evaporation. This can send trees into stress. They combat this by dropping leaves (especially lower leaves that are shaded).
Watering your trees will help reduce stress. We recommend watering with a hose at a trickle for 30 minutes to an hour twice per week depending on the size of the tree. In 95% of cases, trees will re over and be fine!
