New bermuda sod was put down on our new-construction lot in the Dallas area around the first week of last October.

I kept it watered and put down a 15-5-10 fertilizer before winter dormancy set in.

I applied a Lesco 0-0-7 pre-emergent in March, right before green-up started.

I plan on putting down Lesco 3-1-2 or 4-1-2 here in a week or so and following the Bermuda Bible schedule thereafter.

The problem is that my lawn lacks any thickness whatsoever.... it's just flat, with some dandelions and other weeds typical of new, unestablished lawns. It is beginning to green up, but I'm having a hard time understanding if there's more that I should do at this point. Should I just be patient since the roots really didn't have a chance to mature before dormancy set in last Fall?

I'd like to give it the best possible chance for success before the Summer months arrive.
