Kentucky Bluegrass takes about 3 weeks to germinate when both soil temperature and moisture conditions are ideal. Note that cold and/or dry soil can greatly extend the normal germination time.
Does Kentucky bluegrass grow fast?
Kentucky bluegrass rhizomes grow quite quickly and form a thick sod in the spring. There are over 100 cultivars of this grass and most stores selling grass seeds will have a variety to choose from.
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. It does poorly in extremely shady areas.
What temperature does Kentucky bluegrass germinate?
Table 1. Optimum temperatures for seed germination of cool-season turfgrasses.Grass Seed and Seed Germination. Species Temperatures (°F) Kentucky bluegrass 59 – 86 Rough bluegrass 68 – 86 Chewings fescue 69 – 77 Creeping red fescue 59 – 77.
Does Kentucky bluegrass grow slow?
Kentucky bluegrass establishes easily from seed, but it germinates more slowly than some other cool-season grasses. 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.
How do you encourage Kentucky bluegrass to spread?
Because it spreads naturally, Kentucky Bluegrass resists weeds, repairs itself, and forms a lush lawn. To encourage your Bluegrass lawn to spread quickly, apply nitrogen fertilizer regularly throughout the growing season, provide 1–2 inches of water per week, and practice proper mowing methods.
Will Kentucky bluegrass choke out weeds?
KBG can spread quite a bit if the soil is balanced and healthy, and your grass is well fed. It can’t choke out weeds if the weeds are growing, but as a KBG lawn gets thicker and thicker, it makes it much harder for weeds and weed seeds to get a foothold.
Can you overseed with Kentucky bluegrass?
Kentucky bluegrass is one of the better grass seeds to overseed with as it’s a popular cool-temperature grass. It’s known for its dark green color and rich density. The young grass spreads aggressively over the lawn, making it perfect for healing damaged patches of grass through overseeding.
Is bluegrass a self repair?
The leaf blades have a boat-shaped tip; the sides of the blades are parallel, giving a stiff appearance. This species spreads by underground rhizomes that can self-repair injured, worn, or damaged spots. Kentucky bluegrass produces a dense turf.
How long does Scotts Kentucky bluegrass take to germinate?
Scotts® Turf Builder® Grass Seed Kentucky Bluegrass Mix Seed will begin to grow in 7 – 14 days. You can mow the seedlings when they reach 3 inches in height.
How do I speed up grass seed germination?
Use a “mist – lightly water – deeply water” process like this: After seeding and fertilizing, you’ll want to keep the top inch of soil moist until the seeds start to germinate (aka sprout). This means misting the area once a day, maybe twice if it’s unusually hot out there—but don’t let the area get soggy.
Why is Kentucky bluegrass so widely used?
Kentucky bluegrass is often used in roadside mixes because it is widely available commercially and produces dense sod that is good at stabilizing soil. The species has excellent freezing tolerance and is an aggressive competitor such that it will persist in cool climates.
Does Kentucky bluegrass turn brown in winter?
Cool season grasses such as tall fescue and Kentucky bluegrass can turn brown when the temperature gets too high or when it’s under drought stress. Cool season grasses prefer the spring and autumn and go semi-dormant during the hottest time of the summer or the coldest part of winter.
Is Kentucky bluegrass invasive?
Kentucky bluegrass (Poa pratensis) is a rhizomatous grass that is regarded as a crop in some systems, but as a weed in others. However, it is considered an invasive weed in natural grassland ecosystems where it outcompetes native species and reduces biodiversity and alters nitrogen cycling and ecosystem function.
How long should you water Kentucky bluegrass?
Once established, turfgrass should receive approximately 1 inch of water per week, by either rain or irrigation. Mature lawns should receive deep, infrequent waterings, approximately every 5 to 7 days, to promote a healthy, extensive root system. Watering too frequently will result in shallow roots and weaker turf.
How fast does bluegrass grow?
Kentucky bluegrass seed (Poa pratensis) germinates in 14 to 30 days, according to the University of California. It is a popular, dense, dark-green grass that grows well in cooler months and is hardy in all USDA hardiness zones, according to the USDA Maryland Conservation Planting Guide.

Why is my Kentucky bluegrass seeding?
Rhizomes visually resemble roots but play a much different role. Kentucky Bluegrass send their rhizomes through the soil parallel to the surface, and every so often will generate a “node”, from which sprouts up new grass. (May – June), the soil starts to warm up to a point where Kentucky Bluegrass seed would germinate.
