About
Scan. Identify. Treat your lawn with confidence.
Lawn Guardian helps homeowners identify lawn weeds, fungus, disease, and grass problems from a photo — then provides grass-specific treatment guidance so you know what to do next.
Whether you are dealing with brown patches, crabgrass, spurge, chamberbitter, dollar spot, gray leaf spot, large patch, or other common lawn issues, Lawn Guardian helps you move from guesswork to a clear action plan.
Built for homeowners, beginners, and DIY lawn care users, Lawn Guardian works like a weed identifier, lawn disease scanner, grass identifier, and AI lawn care assistant in one simple app.
