I'm a veterinarian in the Seattle area. I spend my days diagnosing patients from symptoms and photos — and kept thinking the same pattern-recognition approach should work for lawns. Every homeowner I know has stood in their yard staring at a dead patch with no idea what caused it or what to do. GrassDx solves that in 30 seconds for free. Would love feedback from the PH community, especially if you try a diagnosis on your own lawn.

Happy to answer any questions about how the diagnosis works or what grass conditions it can identify.
