you need 4 - 6 " of good top soil, water it really deep about every 3 days once it has started. If you water daily your roots grow near the surface because all the water is there. The deeper you water, the deeper your roots grow, making it sturdier, more resilient. Also when it does grow enough to mow it, mow to a longer length. Hold moisture in and actually shades itself. Fertilize with a starter fertilizer when you plant, in the early spring put a pre emergent on it, this will kill the weeds before they grow. I would probably wait until fall to plant it, It will have a hard time growing int he warmer weather. As for what seed to use, go to the local Home Depot ask for someone knowledgeable in ther garden center, and ask what seeds they recommend. If you want a nice lawn don't buy the cheap seed, they add alot of crap into it. While it is starting to grow it will take more watering, you want to keep it wet, but no puddles.
