About this app

Is your lawn getting the care it needs — at the right time?

WhatAGreenLawn takes the guesswork out of lawn maintenance. Using real-time weather data for your location, it tells you when to fertilize, overseed, and scarify, so your efforts actually pay off instead of being wasted on bad timing.

SMART SCORES THAT SAVE YOU TIME & MONEY
• Fertilizer Score — Know the ideal moment to feed your lawn. The app checks temperature, rain forecast, wind, and season to tell you whether to apply now or wait. No more wasted fertilizer washing away in rain or scorching dormant grass.
• Overseeding Score — Seeds need warm soil and moisture to germinate. The app monitors soil temperature and rainfall to tell you when conditions are right, so you don’t waste seed on frozen or dry ground.
• Scarifying Score — Scarifying at the wrong time can damage your lawn. The app recommends when to scarify and which blade type to use (tine vs. flail) based on soil conditions and grass recovery potential.

Each score comes with a clear explanation of why it recommends what it does, plus a 2-day outlook so you can plan ahead.

WEATHER DASHBOARD BUILT FOR LAWN CARE
Not just any weather widget — this one shows what matters for your grass: soil temperature, humidity, wind speed, sunrise/sunset, and hourly forecasts with rain probability. All from your home screen.

MOWING CALENDAR & SEASONAL TASKS
A monthly calendar tells you how often to mow, what height to cut, and the best time of day. Seasonal tasks like weed control and spring clean-up appear automatically when they’re relevant.

GRASS HEIGHT JOURNEY
Track your grass height over the full year. See where you are versus the seasonal target, and know exactly when your lawn enters and exits dormancy.

MULTI-ZONE MANAGEMENT
Front yard, back yard, shaded patch — manage each zone separately with its own settings for grass type, mower type, and cutting height.

LOG YOUR APPLICATIONS
Keep a record of every fertilizer and treatment you apply. Know what you did and when, so you never double-apply or miss a feed.

DESIGNED FOR REAL HOMEOWNERS
Whether you use a robot mower or a push mower, whether you’re a first-timer or a lawn enthusiast — WhatAGreenLawn gives you clear, actionable advice without the jargon.
Set up takes 30 seconds. Pick your location, choose your grass type, and start getting smarter lawn care recommendations today.
