Dean O'--I have never grown buffalo grass from plugs but have grown it from seed many times. Its natural habitat is dry clay soil. Lots and lots of companies sell seed. I used a three part process.
1) The seed is like a bur 1/8-1/4" in diameter and very light weight. The best way to plant it is with a drill where you can get 1/4-1/2" of soil on top of it. Surface seeding and then racking doesn't work nearly as well.
2) Soft fluffy soil dries out much quicker than does hard packed soil. If you're going to water it every week, you can get by with just tamping the seed in. If you're in North Texas and you are going to depend on one or two rains, you want to pack the seed in. Packing means driving over it with a car, truck, tractor or cultipacker.
3) Keep down competition from weeds by mowing the area low until the buffalograss is established.
The first two procedures should only take a day or two. Mowing depends on how fast your weeds grow.
