I aerated and over seeded my lawn earlier this fall. It's been 4 weeks now. Is it safe to use trimec without it harming the new grass (fescue)?
You should not use Gordons Trimec Classic or most other post-emergent herbicides until the new grass is well established. In this case, the product label specifies you will need ot wait until after the second or third mowing of the new grass.
