USDA Zone Map For Rhode Island & Best Grass Seed Choices

Page Index:

Grasses used in Rhode Island generally consist of bluegrass, ryegrass, fine fescue, or mixtures of these grasses. Turf type fescue is also used where drought tolerance is the primary focus and colonial bentgrass is often used in coastal environments.

Cool-Season Grasses:
Kentucky bluegrass is a high quality, sod forming, cool season, shallow-rooted grass with excellent appearance and recuperative potential. It may require frequent irrigation, tends to form thatch and is somewhat disease and insect prone. However, it is extremely cold tolerant and one of the most beautiful grasses there is. It also spreads by rhizomes which helps to repair itself and makes it fairly wear tolerant. Kentucky bluegrass is not the only cool season grass used in Rhode Island. Fescue and ryegrass are two other commonly used cool season grasses.

Perennial ryegrasses are bunching cool season grasses that are compatible in appearance with bluegrass, do not form thatch, have good heat tolerance and may be drought resistant. They tend to be disease prone and offer poor freezing tolerance if flooded or exposed to wind. Perennial ryegrasses is designed for full sun areas, but will tolerate some shade. Ryegrass is bred to give a pleasing dark green color, with a fine texture and excellent mowing qualities. Is also a very good choice for blends with Kentucky Bluegrass and Fine Fescue.

Fine fescues are divided into Chewing fescues, Hard fescues, Red fescues and Sheep fescues. For our purposes they are all grouped together. They are bunching cool season grasses, have a fine leaf texture, offer good shade and cold tolerance, and will adapt to poor soil conditions and fertility.

Tall Fescue - The new turf-type tall fescues are excellent for full sun areas where little maintenance is desired. While they take a little while to establish or recuperate since they are a clump-type grass, they are extremely wear resistant, drought, heat, and salt-tolerant; and moderately shade tolerant. Tall fescues have few disease problems and require less maintenance that other grasses. Kentucky bluegrass is the first grass to brown out in the summer and tall fescue is the last.
