Many lawns are slow to green-up this year and it is mostly due to the presence of Kentucky bluegrass. Even though Kentucky bluegrass is the best lawn grass for the Midwest, it is much slower than perennial ryegrass and tall fescue to green up in the spring (photo). A little patience, some rain, and some more warm temperatures will allow the bluegrass to green-up in the next few days. Though you might want to apply some nitrogen to help it green up, avoid this because too much nitrogen applied now increases shoot growth and the need for mowing.
