A quality lawn containing the recommended mixtures of grass varieties and species can be established with either seed or sod. Perennial ryegrass, annual ryegrass, and Lolium hybridum, tall fescue are essentially established by seed. KBG is easily established by seed, but is also available in sod form.
Tall fescue is sometimes available as a netted sod.
Zoysiagrass and St. Augustine are usually established from sod, or plugs. Seed is not readily available in Arizona for these two grasses. The soil preparation for the two methods does not differ. Initially, seed is less expensive than sod. However, successful, weed-free establishment is more difficult with seed than with sod.
