Perennial Ryegrass (Turf)

asp-perrennial-ryegrassUses

Perennial ryegrass can be used for home lawns, recreation areas, athletic fields and golf courses. It makes an attractive lawn but does require more maintenance than some other cool season turfgrasses like tall fescue and fine fescues.  Perennial ryegrass can be grown alone or in combination with other turfgrasses and it is commonly used as a nurse grass in cool season turf mixtures. In the south it is used to overseed warm season grasses such as bermudagrass. The most commonly used turfgrasses in mixtures with perennial ryegrass are Kentucky bluegrass, tall fescue and fine fescues.

Description

  • Fertilizer: Refer to soil test, responds well to Nitrogen
  • Seed bed:  Prepare a fine, granular and firm seed bed to ensure good seed to soil contact
  • Seeding Rate:
    New Lawn: 5-7 lbs/1000 square feet
    Overseeding Existing Lawn: 3-4 lbs/1000 square feet
  • Seeding Dates: Spring and early fall
  • Seeding Depth: ¼ inch

Management

  • Mowing Height: 1-3 inches
  • Fertility: 2-6 lbs/1000 square feet/year. Apply fertilizer in split applications in spring and fall
  • Irrigation: Irrigating may be necessary to ensure survival during periods of extended drought
  • Weed Control: Apply pre-emergent and post-emergent herbicides at labeled rates to control weeds
  • Disease Control: Apply fungicides at labeled rates to control disease
  • Insect Control: Apply pesticides at labeled rates to control insect problems
