Follow your treatment plan
Dig or spray? Which herbicide? Which products? Prevention tips? It's all there — specific to your weed, in plain English.
Dandelion
Broadleaf weed with yellow flowers and puffy seed heads. Treat with 2,4-D in fall.
Crabgrass
Annual grassy weed that spreads flat. Prevent with pre-emergent in early spring.
Clover
Low-growing broadleaf with 3-leaf clusters. Sign of low nitrogen — fertilize to compete.
Nutsedge
Looks like grass but grows faster with triangular stems. Requires sedge-specific herbicide.
Chickweed
Winter annual with small white flowers. Spreads in cool, damp conditions.
Creeping Charlie
Aggressive spreading broadleaf with scalloped leaves. Treat with triclopyr in fall.

Absolutely not. We give you the plain-English name — Dandelion, Crabgrass, Clover — front and centre. The scientific name is tucked away in small print for anyone curious, but you never need to read it. We answer “what is that weed?” in language anyone can understand.
Upload a photo and our AI identifies the weed species, then instantly generates a treatment plan with chemical and non-chemical options, removal advice, and recommended products. You can also skip the photo and select your weed from our database if you already know what it is.
Yes! Every identification comes with a full treatment plan — whether to dig or spray, which herbicides work best, non-chemical management tips, prevention advice, and recommended products you can buy. For weeds not in our database, AI generates a custom treatment plan.
You can identify up to 20 plants per day, completely free. The limit resets every 24 hours. No account or sign-up required.
