Winter weed control & fertilization
I renovated my lawn(sprinklers installed) last fall with a bluegrass-rye grass-red fescue midwest mix, but had to turn the sprinkling and water system off (mandated) in late spring, due to a severe drought in central Indiana. As such, I lost several areas of the new grass, primarily in unshaded areas, that had germinated the previous fall and looked healthy this past spring. I have not done anything this fall. My thoughts are that I should use Roundup now in areas where I have noted weeds (a few good patches of chickweed in particular) and then follow-up in about 6 weeks with a winter fertilizer or wait until spring and apply a spring preemergent followed up by a healthy spring overseeding 6-8 weeks after that. Somewhere in that time table, I think I should apply fertilizer as well. Does this sound reasonable? Thanks for your replies.
