Late leaf flush on burr oak

Asked November 15, 2016, 7:14 PM EST

This fall I have a large, old burr oak (Quercus macrocarpa) that is pushing out new leaves again after this year's leaves have already dropped. Why is this happening? Should I be concerned.

We were very dry between mid May and mid August and the tree could have been semi-dormant. When the big rains and mild temperatures happened after that, it could have stimulated leaf production from buds made for next spring. This is as good of an explanation as any. There is nothing you can do about this. There should be enough buds for next spring. Time will tell. But this kind of weather has happened in the past and trees survived.
