Lawn care schedule by ZIP code.
Dates are approximate and come from state university extension publications, linked under each task.
How to use it
Type your five-digit ZIP code. The tool uses it only to find your state, then lists when to seed, fertilize, control weeds and mow, with the extension publication behind each window. If a state has calendars for more than one grass, pick yours.

What “approximate” means
Extension publications give months, charts or ranges for a whole state. We read those into dates, so a window is a guide, not a deadline. Weather, soil and where you are in the state move the right day, and a local extension office knows your area better than any state-wide calendar.
If your ZIP is outside the coverage
The tool will say so instead of guessing. Contact the cooperative extension office for your county, or look for your state university’s lawn calendar.
