A general rule of thumb when seeding is to use the best quality seed you can afford. Quality seed varieties are proven better performers due to their resistance to disease, drought and foot traffic. Over the years, this investment can save you hundreds of dollars in treating and watering your lawn. And of course, the best blends also yield a more attractive, thicker, greener lawn. Most lawns in the Midwest are Kentucky bluegrass lawns. However, varieties of dwarf tall fescue are becoming more popular due to their ability to withstand drought and foot traffic. Bluegrass is slow to germinate so it is mixed with a quicker germinating “nurse crop.”
“Nurse Crops” are composed of fine-bladed grasses that come up quickly and provide cover for the bluegrass. Over time, the bluegrass will overtake the nurse crop and cover the lawn. Sowing straight bluegrass on large areas of new lawn is not recommended but is commonly done when over seeding.
Whatever seed you choose to use, apply it at the recommended rate. Over seeding will look good for a while, but crowded plants may eventually die when water is scarce or succumb to disease.
