What Grass Is This? Grass ID

Identify your grass from a photo. Check weeds and brown spots for likely causes. Get a weather-aware lawn plan built for your yard.

What Grass Is This? brings grass identification, lawn problem guidance, and a practical care plan into one app. Start with a scan. Confirm your grass type. See what your lawn needs next.

IDENTIFY YOUR GRASS

Take a clear photo of your lawn. The app identifies common U.S. grass types and asks follow-up questions when the result needs more information.

CHECK WEEDS AND BROWN SPOTS

Photograph a problem area to check likely causes such as weeds, drought, disease, heat stress, or mowing damage. Get clear guidance and a practical next step. When a problem needs local expertise, the app directs you to an extension office or lawn professional.

GET A PLAN FOR YOUR LAWN

Build a plan from your grass type, ZIP code, lawn size, sun exposure, soil temperature, and local weather. See what to do this week, why it matters, and what comes next. Your plan covers mowing, watering, fertilizer, weed prevention, overseeding, dormancy, and seasonal changes.

TIME WORK BY WEATHER AND SOIL TEMPERATURE

Watch local conditions for pre-emergent, seeding, fertilizer, watering, and mowing windows. Use reminders to act closer to the right time.

READ A SOIL TEST

Upload a soil-test PDF. See the extracted values, plain-language interpretation, and recommended actions. Premium can save the result to your lawn and connect it to your plan.

MEASURE AND CALCULATE

Measure your lawn and calculate fertilizer, seed, watering, and other lawn-care needs. Save your lawn details so you do not enter them again.

TRACK WHAT WORKED

Log photos, mowing, watering, treatments, soil tests, and notes. Build a private lawn journal that shows how your yard changes through the season.

USE WIDGETS AND APPLE WATCH

See your next lawn task from a Home Screen widget. Check soil temperature and timing status from your Lock Screen or Apple Watch.
