Already know your grass?
Jump straight into the guide for the grass types we identify most often. Each one has its own mowing, watering, fertilizer, and seasonal calendar.
Bermudagrass
The most popular warm-season grass in America. Aggressive, heat-loving, and incredibly durable for high-traffic southern lawns.
Tall Fescue
A tough, drought-tolerant cool-season grass with deep roots. Excellent for transition zones and low-maintenance lawns.
Zoysiagrass
A dense, carpet-like warm-season grass with excellent cold tolerance for its class. Slow to establish but low-maintenance once mature.
St. Augustinegrass
A broad-bladed, shade-tolerant warm-season grass dominant in the Gulf Coast and Florida. Lush and tropical-looking.
Centipede Grass
The "lazy man's grass," a low-maintenance, slow-growing warm-season option that thrives in acidic soils with minimal fertilization.
Common questions
What people ask before they upload their first photo.
Is the grass identifier really free?
Yes. Upload a close-up photo of your grass and you get the identification plus a quick care plan with no signup, no email gate, and no product upsell. You can use it as many times as you need.
How accurate is the identification from a photo?
Accuracy depends on the photo. A sharp close-up of a single blade taken in natural daylight typically gets a confident match. When confidence is below 70 percent, we tell you so you can re-shoot or check the alternatives we return alongside the top guess.
What kind of photo works best?
Get close. A single blade filling most of the frame, lit by daylight, slightly back-lit if you can manage it. Avoid wide shots of the lawn — they look like green carpet to the model. If your grass is wet or freshly cut, dry it off and let it grow a day before shooting.
Do you store my photos?
Photos uploaded anonymously are processed in memory and discarded after the identification completes. Signed-in users can opt to save photos to their own private lawn journal — those live in your own Supabase storage bucket and are never indexed, sold, or shown to other users.
Will it work for every type of grass?
It covers the ten grass types most common in the US — Bermudagrass, Zoysiagrass, St. Augustine, Centipede, Bahia, Buffalo, Kentucky Bluegrass, Tall Fescue, Fine Fescue, and Perennial Ryegrass. If you have an ornamental, native, or pasture species outside that list, we'll usually return the closest match plus a confidence score so you know it's not a sure thing.
Why do you ask for my ZIP code?
Your ZIP narrows the candidate list to grass types that actually grow in your climate, which improves accuracy a lot. It also lets us tune the care plan to your region's frost dates, summer highs, and soil-temperature trends.
Do I need to download an app?
No — the identifier works in any modern browser on phone or desktop. We also publish a free iOS app for users who want camera-first scanning and lock-screen reminders, but the web tool gives you the same identification engine without an install.
What do I get after the identification?
A grass-type result with a confidence score and alternatives, a region match, a short care-plan preview tuned to your grass and ZIP, and links into our long-form guides if you want to read more on a specific topic like mowing, watering, or fertilizer timing.
