The Complete Seasonal Lawn Care Schedule for Macomb County, MI
Month-by-month lawn care schedule for Macomb County homeowners — exactly what to do, when to do it, and what happens if you skip it.
Michigan Lawns Don't Forgive Bad Timing
Macomb County's four-season climate is both a challenge and an opportunity for lawn care. Done right, the same lawn that looked thin and weedy last summer can be thick and lush by fall. Done wrong — or skipped entirely — problems compound from season to season and become increasingly expensive to fix.
Here's the month-by-month schedule that gets results for Macomb County lawns.
March — Patience
Stay off the lawn. March in northern Macomb County means wet, saturated clay soil that compacts under any weight. Walking on it, mowing it, or working beds when it's soft creates compaction at the root zone that reduces water and nutrient uptake all season. Wait until the lawn feels firm underfoot.
Use March to schedule your spring cleanup, book your mowing service, and order any seed or fertilizer you'll need.
April — Spring Startup
**Spring cleanup:** Remove all leaf debris, cut back perennials, edge beds**First mow:** Once grass hits 4–5 inches — don't rush it**Pre-emergent herbicide:** Apply when forsythia blooms; soil temp target is 50°F**Soil test:** If you haven't tested in 2+ years, send a sample to MSU ExtensionMay — Full Schedule Begins
**Weekly mowing starts:** Target 3 to 3.5 inches height for cool-season turf**First fertilizer application:** Late May, after spring surge calms — slow-release nitrogen**Mulch installation:** After soil temps are above 50°F consistently**Bed planting:** Last frost in Macomb County is typically early to mid-MayJune–July — Manage the Heat
**Continue weekly mowing** — raise cutting height to 3.5–4 inches in July heat**Adjust frequency during drought:** Don't mow stressed, brown turf**Water deeply and infrequently:** 1 inch per week, early morning, rather than daily shallow watering**Watch for grubs:** Japanese beetle larvae hatch in July; treat with preventive grub control by mid-JulyAugust — Renovation Window Opens
**Second fertilizer application:** Late August, as temperatures moderate**Core aeration:** The prime fall window begins — relieve compaction, prepare for overseeding**Overseeding:** Immediately after aeration while soil channels are open**Begin fall cleanup planning:** Book your slot before schedules fillSeptember — Peak Renovation Month
**Aeration and overseeding (if not done in August)****Starter fertilizer for new seed:** Applied immediately after overseeding**Keep new seed areas moist:** Water lightly 2–3x daily until germination**Fall weed control:** Post-emergent broadleaf herbicide highly effective in early fallOctober — Wind Down
