OK, so we just bought a house and the backyard is shot to hell. We already went through it with mower/weedwhacker to get the lawn area looking clean, but the problem is what to do now? The grass that was there is pretty much dead, except in patches. The weeds almost completely took over, and I'd like to make the lawn semi decent-looking to spare the embarassment when people come over.

I guess my question comes down to this: what can I do to get the lawn green in the quickest manner possible? I think it bears consideration that I live in phoenix so bermuda grass is the grass of choice to reseed.

Thanks in advance!
