About the startup
GrassDx is a free AI lawn diagnosis tool built by a veterinarian. Upload 1–4 photos of your lawn, enter your ZIP code, and get an instant diagnosis with a treatment plan localized to your grass type, climate zone, and current season. Unlike generic lawn care advice, GrassDx knows the difference between brown patch fungus in Houston in August and the same-looking problem in Seattle in May, because the cause and treatment are completely different. Free. No account required. Works on any phone. Identifies 47+ conditions including brown patch, dollar spot, grub damage, chinch bugs, take-all root rot, iron chlorosis, lawn rust, and more. Each diagnosis includes DIY treatment steps, product recommendations, and local professional help options. Built by Andrew Rocco, DVM, applying clinical diagnostic methodology to lawn care.
