I started working on this yard but to no avail pulling weeds. I nuked the lawn with Roundup and then tilled it. Tilling it only awoke many more dormant weeds but I didn't know that. I planted and watered. I then had to hand pull litterally millions upon millions of Spurge and Crabgrass weeds. Where it was so fiercely bad, I re-nuked areas and replanted grass seed. I've spent many many man hours pulling weeds and filling 5 gal buckets, too numerous to count. The lawn is now looking halfway ok, but there is more work to be done. This spring of 2012, I hope it's good news when it starts to grow and most of the weed seeds are again laying dormant. I would like to just mow and water the lawn, not walk it for hours each day pulling weeds.
