Wanted to get some advice on establishing a new lawn....
Bought home a couple years back in the Pacific NW, but didn't notice
the problems I'd have with the back yard. There's a pretty hard clay
under almost no topsoil. Last year, in an attempt to improve things,
I dethatched a pretty thick layer of thatch, aerated, added some
topsoil and overseeded. Unfortunately, I thought a crabgrass problem
I had was small and could be overcome by the seeding and selective
spraying. Didn't work. By Summer, the crabrass was pretty thick.
Decided to kill the lawn and start from scratch. My plan is to bring
in some more topsoil and rototill into the clay, and then seed or sod
in the Spring. Here's the problem.... the grass and crabgrass appears
to be dead on the surface, but I dug a small trench just to get a
better idea of the clay problem, and found the crabgrass roots
What's the suggestions for getting the soil ready for planting in the
Spring? I could reapply Roundup on the crabgrass when I see it
sprout, but I want to make sure it's gone. I was just going to till
in the sod instead of getting a sod cutter since it appears the
crabgrass goes pretty deep anyway, but should I rent the sod cutter
anyway, just to eliminate as much of the problem as I can?
