Many new and improved varieties have finer texture, higher tiller densities, and a darker-green color than the coarse-textured, light-green varieties such as 'Kentucky 31' and 'Alta.' Tall fescue is considered by many individuals to be incompatible with the finer-textured and darker-green Kentucky bluegrass, perennial ryegrass, and fine fescues.

Tall fescue is primarily a bunch-type grass that occasionally produces short rhizomes. It is somewhat slow to establish extensive root systems and has only fair recovery potential. This species is the most heat and drought tolerant of the cool-season turfgrasses.

Fescue Grasses

Fescue grasses do well in the autumn. Sow 6 to 8 lbs. of fescue seed for every 1,000 square feet of lawn. Keep the grass watered with at least 1 1/2 inch of water each week for the first month or two. Once it is established, it is drought and cold tolerant.

Rye Grasses

The rye grasses are also appropriate for October planting in warmer climates. Sow 3 to 5 lbs of winter rye seed per 1,000 square feet of existing grasses or use 5 to 7 lbs of seed for 1,000 square feet of bare earth. They need two to four weeks of frost-free weather to become established, so adjust the planting date for your area.

Bluegrasses

Bluegrass seeds are best planted in the early fall, but planting as late as Oct. 15 is often successful. With late planting, mix in approximately 40 percent rye grass seed. The rye grass germinates quickly and provides cover for the bluegrass over the winter.

Overseeding

Overseeding is used to fill in bare spots or to alternate between cool-season and warm-season grasses. Before sowing the seed, mow the lawn to approximately 1 to 1½ inches. Sow the seeds at a rate of half the amount indicated for a new planting.

Preparing a New Lawn

Prepare the soil before planting by leveling the seedbed and mixing in nutrient-rich organic compost. Spread the seed evenly over the area and rake it gently to bury the seed. Water with a fine spray to avoid washing the seeds away.
