7 Lawn Care Mistakes Michigan Homeowners Make Every Year

The Most Common Michigan Lawn Care Mistakes

Michigan's cool-season grass requires specific care — and when homeowners treat it like a warm-season southern lawn, results suffer. Here are the seven most common mistakes we see in Macomb County and Oakland County, and how to fix them.

Mistake 1: Mowing Too Short

The most common mistake in Michigan. Cutting cool-season grass below 3 inches weakens roots, invites crabgrass, and causes brown spots during summer heat. Keep it at 3–3.5 inches all season. The "one-third rule" applies: never remove more than one-third of the blade at once.

Mistake 2: Watering at Night

Night watering leaves the lawn wet through darkness, creating ideal conditions for fungal disease. Water in the early morning — before 9 a.m. — so grass dries through the day.

Mistake 3: Skipping Fall Fertilization

Most Michigan homeowners fertilize in spring and forget fall. Fall is actually the most important application. A late-season nitrogen push builds carbohydrate reserves and strong roots for spring green-up.

Mistake 4: Bagging Clippings Every Week

Clippings are free fertilizer — they return nitrogen to the soil as they decompose. Only bag if the grass is too long (more than 4 inches) or wet. Regular weekly mowing clippings should stay on the lawn.

Mistake 5: Aerating in the Wrong Season

Spring aeration is effective, but fall is better. Late August through September aerations allow roots to grow into the open channels before frost without summer heat stress.

Mistake 6: Ignoring Thatch

More than half an inch of thatch blocks water, air, and nutrients from reaching roots. If your lawn feels spongy or looks thin despite regular watering, dethatching or aeration is the solution.

Mistake 7: Not Overseeding After Aeration

Aeration without overseeding misses an opportunity. Aeration holes are perfect seed beds — always follow core aeration with quality overseeding for maximum turf density.
