What Goes Into Every Diagnosis
Not a chatbot. Your lawn's agronomist.
Before GrassDX looks at your photos, it assembles a real-time profile of your lawn's environment — from federal soil surveys to live weather data. Most AI tools guess from your ZIP code. GrassDX looks it up.
Exact Location
Your city and state resolved in real time — not a ZIP string handed to a general-purpose chatbot.
USDA Hardiness Zone
Your actual zone (e.g. 8b or 9a) pulled from federal plant hardiness data, not inferred.
Soil Type
From the USDA Web Soil Survey — the exact soil series at your coordinates, like "Alderwood gravelly sandy loam."
Live Temperature & Humidity
Current conditions at the moment of your diagnosis, not seasonal averages or historical norms.
7-Day Rainfall Total
Recent precipitation is the biggest factor separating drought stress from fungal disease. We look it up.
Exact Date
Advice is season-specific. June in Zone 8b requires completely different care than October in Zone 8b.
Sun Exposure
Full sun vs. deep shade changes which grass thrives, which diseases appear, and which treatments work.
Watering Habits
Rain-only vs. irrigation changes drought risk entirely and affects which diagnoses are even plausible.
Fertilizer History
When you last fertilized helps distinguish nutrient deficiency from disease or pest damage.
Lawn Health Index
A score that means something.
Every diagnosis generates a Lawn Health Index — five dimensions of your lawn's condition, each scored independently and combined into one number. A real baseline you can track over time.
Coverage — grass density and fullness
Disease — freedom from fungal and pest damage
Weeds — pressure across the entire lawn
Stress — drought, heat, and nutrient deficiency
Urgency — how immediately action is needed
