Your Southeast Wisconsin Lawn Care Schedule
How to use this calendar
Treat these as windows, not fixed dates. Lawns respond to soil temperature and moisture, not the page on the calendar, so each step moves a week or two from year to year. The sequence, though, stays the same. Here is how the season unfolds for a typical Southeast Wisconsin lawn.
April / May — Pre-emergent
The season opens with a crabgrass preventer, applied before soil temperatures hold near 55°F. This stops crabgrass and other annual weeds before they start.
May / June — Targeted weed control
As broadleaf weeds like dandelion and clover appear, a targeted herbicide knocks them back while the lawn is growing strongly and can fill in the gaps.
July — Summer feeding
A controlled-release feeding (ProPeat 17-0-4) carries the lawn through the heat with even color and soil conditioning, without the burn risk of fast-release nitrogen.
August / September — Targeted weed control
A second round of weed control cleans up late-season broadleaf weeds and sets the lawn up for its most important feeding.
October / November — Fall winterizer
The season closes with a winterizer (ProPeat 10-0-10 with Iron) that builds root strength and stores energy for a faster, greener spring.
Do it yourself, or hand it off
You can run this schedule on your own, but the timing — especially the spring pre-emergent and the summer feeding — is where most DIY programs slip. Our 5-application program follows this exact sequence and adjusts each visit to the season’s conditions.

Frequently Asked Questions
What is the best lawn care and fertilizing schedule for Southeast Wisconsin?
A healthy Southeast Wisconsin lawn follows a simple seasonal rhythm: pre-emergent in April or May, weed control in late spring, a light feeding in summer, more weed control in late summer, and a winterizer in fall. Here is the month-by-month version, adjusted each year to the weather.
