Lawn that require moderate to high input and grow best in a sunny location require that it is watered well throughout the season. Fertilize 4 applications of 3/4 to 1 pound of nitrogen for every 1,000 square feet of lawn. Mowed properly according to how fast the lawn grows, remove no more than 1/3 of leaf tissue when mowing.The cool-season grasses include turf-type tall fescue, Kentucky bluegrass, perennial ryegrass, and fine fescue. Cool-season grasses grow best in the spring and fall when air temperatures range between 60 and 75 degrees F. The best root growth occurs when soil temperatures range between 50 and 65 degrees F.
The recommended seed mix is seed with a blend of improved Kentucky bluegrass varieties or a Kentucky bluegrass/perennial ryegrass (turf-type) and a fine fescue species(hard, chewings red, and creeping red fescues). Most tall fescue varieties are too coarse and clumpy for a quality lawn.Tall fescue is a favorite for nonirrigated turf. Ryegrasses are heavy users of water and their performance is less than optimum during a drought or periods of extended low or hightemperatures. Perennial ryegrass is marginally hardy and is less likely to survive a brutally cold winter. Penn State Researchers have observed seedhead production by perennial ryegrass during mid-summer regrowths. Some turf managers prefer to mix tall fescue with Kentucky bluegrass. Such mixtures of two or more compatible species often produce a better-quality turf than a single species because one of the species will be more resistant to prevailing diseases or other stresses that
come over time. Seed distributors often sell turf-type tall fescue blends that combine several different tall fescue cultivars. Perennial ryegrass has good wear tolerance and germinates very quickly in spring and fall.
