  3. Don’t overwater. Bluegrass needs about one inch of water a week considering rainfall.
  4. Apply fungicide if needed.

Will Kentucky bluegrass fill in bare spots?

Kentucky bluegrass has a moderate growth pattern and does spread and will fill in bare spots. The grass will go dormant in hot, dry weather as well as during the cold winter months common in North America.

Will Kentucky bluegrass take over fescue?

Fescues grow in bunches that don’t form as dense a sod or spread as well as Kentucky bluegrass rhizomes. You have to reseed bare patches of fescues, while Kentucky bluegrass will heal them itself. Kentucky bluegrass turf requires more fertilizer and more frequent mowing than fescues.

Can you mix Kentucky bluegrass and tall fescue?

Seed mixes consisting of 80 to 90 percent (by weight) tall fescue and 10 to 20 percent Kentucky bluegrass seem to work well. Use Kentucky bluegrass and perennial ryegrass in areas that receive irrigation.

Will bluegrass take over fescue?

Bluegrass will–but bluegrass is not as heat tolerant as tall fescue. Even the creeping varieties of tall fescue–are very slow to creep–bluegrass is much faster. Socombine the two to get the best of both worlds and add some fine fescue for shade tolerance.

Does Kentucky blue grass stay green all year?

These types of grasses are referred to as “cool-season” grasses and stay green year-round in temperate climates. For shady areas, bluegrass (often called Kentucky Bluegrass) is a cool-season variety that has a higher shade tolerance than fescue.

How fast does bluegrass spread?

Higher seeding rates ensure quicker ground cover. Kentucky bluegrass is slightly slower to establish than many other cool-season grasses. The slow establishment is primarily a result of slow (approximately 14 days) germination. However, once established it spreads quickly via its extensive rhizome production.

Can you plant Kentucky bluegrass in the summer?

As with other cool-season grasses, Kentucky bluegrass growth slows significantly during hot summer months. During extreme heat or extended drought, the grass will go dormant. Kentucky bluegrass prefers full sun, but some varieties can do well in lightly shaded areas.

When should I put nitrogen on my lawn?

A general rule is to apply the last nitrogen fertilizer to a lawn that contains warm-season turfgrasses two months before the first frost. Unless you live in the deep south, the last application of a fertilizer that contains a high amount of nitrogen would be September 15 at the latest.

Where does Kentucky bluegrass grow best?

Kentucky bluegrass grows best in the humid areas. Optimum temperatures for forage production are between 60 °F and 90°F. Although the grass is essentially dormant during dry or excessively hot weather, it survives severe droughts. It prefers sunlight but will do well in light shade with ample moisture and nutrients.
