I'm not talking a clump here and there, but large tracts of the stuff, and this is despite having thick grass which grows up around it. I already mow to 3" when the lawn is 4".
The man at the locally owned nursery said this is because crabgrass had perfect conditions before the grass greened up this year.
Is the lawn a goner? Is there anything I can do to minimize the damage? This stuff has already set seeds and there's just too much to hand weed. Nuking it would leave large bare spots all over the lawn.
I've put so much effort into reclaiming what had been a crabgrass/hay field and turning it into a lovely lawn that it's really a bummer to see it deteriorate.
