The Best Time to Plant Grass in Michigan

Turf Grass

• Turf grasses suitable for lawns in Michigan include fine-leafed fescue, Kentucky bluegrass and perennial ryegrass, according to Michigan State University Department of Horticulture. It is best to plant these in late summer, which gives the seedlings a chance to grow and root properly before the harshness of winter. Seed turf grasses between August 15 and September 15 in southern Michigan. In northern Michigan, wait and seed between August 10 and September 1. You can sow dormant seeds as late as November, because the cool temperatures will prevent germination until spring, but spring and early summer seeding leaves seedlings vulnerable to drought and scorching sun.

Cool-Season Wild Grass

• Cool-season wild grasses include timothy, alfalfa and clover, which provide an excellent ground cover. These grasses grow best during mild days and cool nights; take advantage of the season by planting in spring and early summer. Any time between April 15 and June 1 will work, but earlier is better.

Warm-Season Wild Grass

• Warm season wild grasses include switchgrass, bluestem and Indian grass, and are a low-maintenance way to landscape high-acreage properties. These grasses grow best when the days are hot and the nights are warm; take advantage of the summer months to get the seedlings established. Southern areas can sow as early as April 15, but northern areas may wait as late as June 15.
