What would be a good program for a blue grass blend lawn?
Wayne County Michigan lawns and turf
The lawn care recommended at the MSU Home Turf Care site will guide you.
Current research recommends mowing no shorter than 3.5 inches, 4 inches long is better. The longer the blade is left after mowing, the better the root development. When mowing, taking no more than 1/3 of the total blade length off at one mowing.
Provide irrigation equivalent to 1 inch to 1.5 inches of water per week( including rain), divided across 3-5 days.
Fertilize based on a soil test. https://www.canr.msu.edu/resources/dont_guess_soil_test_get_your_home_lawn_and_garden_soil_test_kit_today
Bluegrass requires about 4 lbs per 1000 sq ft nitrogen per season, divided up into applications of no more than 1 lb per 1000sq ft applied at any one time. The last application is typically done in September or October, before the ground freezes.
