I have large areas of solid Dallisgrass in my yard. We have started removing each individual clump by hand but is an incredibly slow process, even with my handy weed popper.
So for my next non-chemical plan of attack I want to lay down black plastic and once this perennial evilweed is dead, I'll till it in and reseed the area.
Has anyone does this proceedure specifically on Dallisgrass? How long do I need to keep the area covered? Will this also kill the seeds or will I have to treat the area prior to covering with corn gluten meal?
