Common Name: Various mixtures of Tall fescue, Kentucky Bluegrass, Fine fescue, Ryegrass, and others
Latin Name: Various, see individual species
Strengths: Shade tolerance, cold tolerance, diversity in mixtures, most mixtures and blends are easily established by seed
Weaknesses: Varies by mixture or blend
Growth Habit: Dependent upon species composition
Mowing Height: 1 to 4 inches with a rotary mower; dependent on mixture composition
Mowing Frequency: Weekly during the growing season
Fertilization Requirement: Single application rates; 0.5 to 1 lb of Nitrogen per 1,000 sq feet during the growing season months. Annual application rates; 1 to 3 lbs of Nitrogen per 1,000 sq feet per year. Application of other nutrients including Phosphorous, Potassium, and others should be based on soil test results.
Description: There are many blends and mixtures of cool-season grass available as both seed and sod. Blends refer to products that contain two or more varieties of grass within the same species, while mixtures refer to two or more varieties of different species. It is quite common for seed producers to produce blends and mixtures which take advantage of the different strengths of each grass. For instance, fine fescues are often blended with Kentucky Bluegrass and/or Tall fescue to increase shade tolerance. Kentucky bluegrass may be blended with ryegrasses or fescues to add the rhizomatous growth habit of Kentucky bluegrass to the bunch-type growth habit of ryegrass and fescue. When choosing a blend or mixture, be sure to select one that is the best fit for your particular region, lawn characteristics, and needs. Seeding rates are dependent upon species composition so consult the label before planting. Cool-season blends and mixtures are also commonly available as sod.
