Late summer and early fall provide the most ideal conditions for turfgrass establishment. Generally, this timing will allow adequate grass growth prior to winter. Cool evening and moderate daytime temperatures, along with anticipated fall precipitation, are conducive to rapid seed germination. In addition, many weeds including crabgrass are no longer germinating, reducing competition in new turfgrass plantings.


Seed Selection: Many advances have been made by turfgrass breeders in recent years. For instance, there are now Kentucky bluegrass varieties better adapted to moderate shade, as well as improved disease resistance. Tall fescues, just a few years ago, were considered stemy, coarse grasses. Today, finer leafed, lower growing, denser and darker green tall fescues are available. The same can be said for perennial ryegrasses. Fine leaf fescues, such as hard fescue and creeping red fescue, are known for their adaptability to shady areas and “droughty” soil. New improved fine fescues are also available.

In addition, the issue of seed mixtures is an important consideration. Reputable seed companies provide mixtures of “improved” varieties of various species allowing a wider range of site adaptation. Mixtures of various turfgrass species, each selected for a specific trait, provide the best opportunity for successful lawn establishment if a site has a combination of wet, dry, sunny and shady areas.

A brief description of the characteristics of the major species of lawn grasses is outlined below.

  1. Kentucky Bluegrasses (Poa pratensis) This is a popular lawn grass in New Jersey. It is hardy, attractive, widely adapted and known for its pleasing color and leaf texture. New varieties have some shade tolerance and improved disease resistance. It is suitable for moderately to well-drained soil but is somewhat slow to establish from seed. Spreading underground rhizomes (stems) enhance recovery from injury and fill in voids. Seeding rate is approximately 2 pounds per 1000 square feet. Spring seedlings are difficult to establish.
  2. Tall Fescues (Festuca arundinacea) This is a coarser bunch-type grass able to persist in moderate to well-drained, infertile soils. Newer varieties are improved in leaf color, texture and density. Tall fescues are also known for rapid establishment from seed, excellent drought tolerance and ability to tolerate traffic. Seeding rates are 4 to 6 pounds per 1000 square feet.
  3. Fine Fescues (Festuca spp.) Fine fescues are comprised of several species (hard, sheeps, creeping red). As a group, they are known for their ability to persist in shady areas as well as in dry infertile locations. They establish slightly faster than Kentucky bluegrass. Improved newer varieties are useful for lower maintenance turfgrass areas. Fine fescues do not tolerate high traffic. Seeding rates are 4 to 6 pounds per 1000 square feet.
  4. Perennial Ryegrass (Lolium perenne) Breeding advances have produced varieties markedly improved over the older non-persistent types. These newer turf type ryegrasses have excellent color and fine textured leaves. They survive in a wide range of soil conditions but grow poorly in extremely wet areas. They possess moderate shade tolerance and very rapid establishment. Seeding rates are 4 to 6 pounds per 1000 square feet.
