4 min read

Are you frustrated with your lawn in Michigan? When it has at least 50% healthy turf, learn the best way to overseed and rejuvenate it from the experts at Jonathan Green. We can help you grow a healthier, better-looking lawn that will not be subject to most lawn problems.

About Jonathan Green

Jonathan Green is a leading supplier of cool season grass seed, soil enhancers, fertilizer, and organic lawn and garden products to professional customers, such as sod growers and independent retailers, including garden centers and hardware stores, throughout the Northeast, Mid-Atlantic and Midwestern United States.

We have been growing great looking lawns for six generations, ever since our English ancestor Jonathan Green set out to grow turf grass in 1881 that would beautify bowling green turf all over the north of England.  Today, the family remains committed to producing superior lawn and garden products.

Best Time to Rejuvenate Your Lawn in Michigan

If your lawn is looking thin and unhealthy, or you struggle with crabgrass and bare spots that just won’t go away, it may be time to overseed it. Overseeding means planting grass seed over an existing lawn without removing the turf or the soil.

In Michigan, early fall is the best time to overseed. Soil temperatures are still warm, which is necessary for optimum seed germination, and cooler air temperatures are better for grass growth. There are also fewer weeds for the grass to compete with at this time of the year. With adequate sunlight, rainwater and fertilizer, you can expect the new grass seedlings to be well-established before the cooler fall weather arrives.

Your lawn will never be better than the grass seed you plant, so we recommend overseeding with either Black Beauty® Ultra Grass Seed mixture or Black Beauty® Fall Magic Grass Seed mixture:

  • Black Beauty® Ultra Grass Seed is most similar to what is found on sod farms. The mixture possesses species diversity and contains exclusive, elite varieties of tall fescue, Kentucky bluegrass and perennial ryegrass.  These grasses grow a naturally dark-green and beautiful lawn with excellent heat and drought tolerance.  Black Beauty® Ultra Grass Seed germinates in about 14 days and will improve any lawn it is overseeded into.
  • Black Beauty® Fall Magic Grass Seed has been specially formulated for successful fall seeding and contains several grass types, including Black Beauty® tall fescues. It can be used in sun and shade lawn areas on established lawns or to start new lawns from scratch. Black Beauty® Fall Magic Grass Seed repairs summer damage and provides an attractive, thicker, greener lawn, with germination in 10 to 14 days.

In addition to Jonathan Green genetically superior grass seed, healthy soil is the key to having a beautiful lawn. Before you begin, soil problems (pH and/or compaction) must be corrected. Grass seeds thrive in soils with a slightly acidic to neutral pH (6.2 – 7.0), while weeds persist and are harder to eliminate in acidic soils with a lower pH. You may also need to dethatch the existing lawn so the seed can make contact with the soil. Please refer to our Seeding Guide for more information.
