Plant Diagnosis

Plant Problems

Start with the symptom you can see. Compare likely causes before changing water, fertilizer, light, or treatment.

Triage First

Observe before you treat

A useful diagnosis starts with location, timing, and the pattern of damage.

1

Locate the damage

Check whether symptoms begin on old leaves, new growth, roots, or one side of the plant.

2

Check recent changes

Note weather, watering, repotting, feeding, pruning, and any new treatment.

3

Compare evidence

Look for insects, residue, soft tissue, dry edges, odor, and soil moisture.
