Why are these leaves yellow?
Look at which leaves changed first, root-zone moisture and recent feeding.
Plant problem checks for iPhone
Show what changed on your plant. See what to check first.
Photograph spots, yellowing, wilting, pests or another visible change. Add when it began and whether it is spreading. Garden Sage shows what the photo supports, plausible causes and one practical next check.

From symptom to next check
Start with the pattern, not a diagnosis.
The same symptom can have several causes. Pair the photo with timing, distribution and recent care so the next check is grounded in this plant.
- 01
Choose one useful view
Use a whole-plant photo when distribution matters, or one close view that includes affected and healthier tissue together.
- 02
Say what changed
Add when you first noticed it, whether it is spreading, and any recent weather or care change.
- 03
Check the most useful clue
Review what the image supports, plausible causes, uncertainty and one practical next observation.
Questions from the garden
Ask about the change you can actually see.
A specific observation gives the check somewhere useful to begin. You do not need to arrive with a diagnosis.
Are these marks spreading?
Compare pattern, texture, leaf position, weather and the rate of change.
Why is this plant drooping?
Check heat, root-zone moisture, stems and whether it recovers overnight.
What caused this visible damage?
Inspect both sides of the leaf, then photograph the clearest evidence of residue, pests or physical injury.
Make sense of the signs
Separate observations from possible causes.
Garden Sage is designed to show the visible evidence, plausible explanations, what to check now and what remains uncertain. That helps avoid treating a guess as a fact.
- What the photo showsLocation, colour, pattern, damage and other visible clues.
- What might explain itPossibilities stay separate from observations and confirmed facts.
- What to check nextOne practical observation before a broad treatment or care change.
Important limits
What a photo cannot establish.
A photo cannot inspect roots or soil, confirm a pathogen, prove toxicity or safely choose a pesticide by itself. Garden Sage narrows the next check and can point to professional help when the consequence of error is high.
Do not use an app result alone for poisoning, foraging, pet safety, pesticide choice, serious tree hazards or another urgent, high-consequence decision.
Read the uncertainty and escalation policy
Follow the plant, not the guess
Save the next step with the plant.
Keep the dated result, any watering or feeding you log and a later separate photo check together rather than starting again from memory. Time and response can reveal what one photo could not.

Check the pattern before changing care.
The product page explains the app workflow. These editorial guides show how to inspect common plant symptoms in more depth.

Start with the change you can see
Take the photo before the pattern changes.
