Illustrated problem solver
Compare visible symptoms, keep multiple causes open, and choose low-risk next steps.
Start with what you can see
Possible causes, not a diagnosis
Yellow leaves
Leaves lose green color between veins, from the edges, or across the entire blade.
Check first
- Are the oldest or newest leaves affected first?
- Is the root zone wet, dry, or compacted?
- Is yellowing uniform or patterned?
- Did conditions change recently?
Low-risk next steps
- Check moisture below the surface before watering.
- Remove only badly damaged foliage.
- Review drainage and recent fertilizer use.
- Compare the pattern with crop-specific extension guidance.
How to use the result
A plan is a starting hypothesis.
Confirm crop-specific guidance, compare the recommendation with current conditions, and revise when the garden gives you better evidence. Inputs remain on this page while you work but are not stored as an account or permanent record.
