More aggressive types of grass

Asked May 30, 2018, 9:54 PM EDT

Thanks for your time.
I need to patch several areas of my lawn Several years ago I had new Blue Grass sod install so I'm certain of the type of grass I have. All of the products that are on the market and labeled as "patching products" have a variety of seed in them. They have assorted types of Rye, Fescue, as well as Blue grass. My question is, will one type of this grass be more aggressive and essentially germinate and then take over the area? I'd like the bluegrass to be dominate and over take the others . Should I use just bluegrass seed? (The straight BG seed) takes longer to germinate . Also, have I waited too long to attempt new grass seed planting. again ,Thank You

When you purchase grass seed to patch your existing lawn, select a high quality seed mix that is best adapted to the specific location in your yard. Kentucky bluegrass (KBG) is the best choice for sunny areas. Choose a seed mix that contains at least two or three bluegrass cultivars. Because Kentucky bluegrass is slow to establish from seed, perennial ryegrass is often included in bluegrass so it establishes quicker. Perennial ryegrass contained in a high quality bluegrass mix is usually about 20%. The fine leaf fescues (hard fescue, creeping red fescue, and chewings fescue are the best grasses for shady locations. In lawns that contain sun and shade, your best bet is to choose a seed mix that is approximately 60% KBG, 30% fine leaf fescue and 10% perennial ryegrass. Kentucky bluegrass will be the dominant grass in the sunny areas, while the fescues will thrive in the shaded part of your lawn. You can purchase grass seed in bulk for your particular needs at any independent garden center.

Your best bet for seeding would be late August into early September.
