over seed lawn #851405

Asked September 27, 2023, 1:16 PM EDT

This summer, tree removal from our yard resulted in extensive lawn damage. We did not attempt to repair the damage because of the dry conditions. How late into the fall can we over seed areas and expect any newly germinated grass to survive the winter? Would it be better to wait until next spring to repair the lawn?

Thank you for the rapid response, We have about 1.5 acres that we manage. There is a population of older silver maple trees. We mulch all the leaves and clippings in place. Usually I have to mulch well into November in order to deal with the volume of leaves. Does this change your thoughts on how I should deal with over seeding?

The ground must be raked and dethatched for the seeds to get to the ground.  Otherwise, rake in the spring. See the link that I sent.
