want to re-seed my lawn but waiting till leaves are off my bradford pears. Will they be pretty much done falling before weather drops below 45 degrees?
It can be hard to tell, exactly, when trees will lose the very last leaves. I would guess that it should lose most of them at that time, but I wouldn't be inclined to say they will all have fallen. It would have to stay cold for a good period of time to coax the tree to shed its leaves.
