Lawn care, timed to your weather
Specific answers to the timing questions that decide whether a lawn thrives: when to feed, how short to mow, when to overseed and when to leave it alone. Written for your climate, from the same rules the What a Green Lawn app checks against your forecast every day.
How the app works
- Add your lawn. Draw it on the map and the app works out its size, so product amounts match your garden.
- Every day it scores feeding, overseeding and scarifying against your local forecast, and suggests a mowing height for the weather.
- Log what you did. The calendar plans the next job around your grass type and the season.
