Why Doesn’t My Linden Tree Drop It’s Leaves In The Fall?

Question

The leaves turn a dusty brown color and stay on the tree until new leaves force them to fall in the spring. I also have an oak that doesn’t drop leaves in the fall in the same way.

Answer 1

Certain types of trees are prone to this. Oaks, certainly, are. Linden will be no stranger to it, as well. This happens when the lack of formation of abscission tissue occurs. Generally, this has two causes.

One is when there is sudden cold weather in autumn, which prevent the formation of abscission tissue.

The other is when the winter remains too warm for drop. This, also, prevents abscission tissue formation.

Neither will harm your trees. They will return to normal as soon as the active growing season starts.
