Thanks for the tips guys.
I have done some research and found that I have bermuda grass (great in my semi-arid climate).
It has also been suggested that I aerate the soil soon (we have sandy/clay compacted soil in our region) and at most twice per season thereafter.
I have HUGE goosegrass/broadleaf weed problems right now, which I think I will deal with first (I am almost done pulling all of it in the front yard--it was EVERYwhere).
My plan of attack for weeding:
Pull all weeds
Spray remaining roots with Ortho's Weed-B-Gone
Drop-spread Scott's weed and feed product
Seed with Scott's Bermuda Grass mix to fill in the bare spots
After the newly germinated grass is able to be cut for the 1st time, drop-spread
Scott's fertilizer/fire ant killer
I think that should take care of the front yard.
I am wanting to start all over with the back lawn because the grass is tall fescue, which looks weedy to me and is kinda sparse. But that will be done later after we have the patio and rear drive poured (probably in a year after I get out of school).
DE31, do you have some updated pics of your backyard?
and btw, I will never make fun of people who spend all weekend on their yards (not that I ever did). This is tough work. I spent over 13 hours weeding my front lawn over the past 3 days!
Big lawns are over-rated.
