Tall fescue - Turf Type - These grasses are well adapted to a wide range of soil conditions. Tall fescues tolerate heat and drought better than most cool season turfgrasses due to their deep root systems (4 to 6 feet). Fescues can withstand traffic and heavy use and are often used on football and other playing fields. The new turf-type tall fescues, especially the new dwarf varieties are thinner bladed than older varieties. Since fescues do not spread by stolons or rhizomes (except newer types), they do not form thatch. Fescues are usually planted as a monoculture (a pure stand of a single species). They do not accept low mowing. Their fertility requirements are low to moderate
Kentucky bluegrass - This is probably the most traditionally used cool season grass. Monocultures of Kentucky bluegrasses are not recommended in Southern Idaho because of insect and disease problems. Bluegrasses, however, may be a part of most grass mixtures. Bluegrasses are slow to germinate and establish. They are good at repairing damaged turf areas because of their ability to spread. This can be a problem when flower beds border turf areas. Bluegrasses have a moderate to high fertility requirement.
Warm-Season Grasses:
Buffalograss - These warm season stoloniferous grasses, due to their drought resistance, are becoming popular in the West, even in cool season areas. Buffalograsses are resistant to heat and drought. They are well adapted to a wide range of soils, but especially to alkaline conditions and soils of low fertility. Buffalograsses are slow to establish (1 to 3 years) and they require infrequent mowing. Like most warm season grasses, they have a short growing season (4 to 5 months) in the north due to their inability to withstand cold weather. Hence, during half the year or more in Idaho, a buffalograss lawn will be tan or brown in color.
