Answer a few quick questions, one at a time — it only takes a minute. It reads today's date and region automatically since a lot of these problems are season-specific.
Plant Problem Diagnoser

Step 1 of 4 — Your Plant
🌱 What kind of plant is this?
📍 Region
📍 Where are you seeing this?
This is one of the biggest diagnostic clues there is — one sick plant points to something very different than a whole bed. Skip if you're not sure yet.
🍃 Leaf Symptoms
Select everything you're seeing — it's fine to pick more than one, or none at all.
🌿 Plant Behavior
Last step — select anything that describes how the plant is acting, then get your diagnosis.
Season is detected automatically from today's date and your selected region, and factored into the ranking — you don't need to enter it manually. It's fine if you don't know the pattern yet (whether it's spreading, isolated, etc.) — select "Not sure yet" rather than guessing, and the tool will rely more heavily on the symptoms you do know. If you've looked closely and genuinely see no insects, mites, or slug trails, select that too — it substantially discourages pest diagnoses (since insects are easy to miss or may have already moved on), but a genuinely distinctive pest symptom like sticky honeydew residue can still come through. Rankings favor whichever culprit explains the most of what you selected overall, not just whichever one symptom happens to carry the heaviest weight, how common a problem actually is for that plant factors in when two explanations fit similarly well, and a handful of hallmark symptoms — a true white powdery coating, sticky honeydew, fine webbing, orange rust bumps, a V-shaped leaf lesion, club-shaped roots, soggy or bone-dry soil, and a few others — are close to decisive on their own and actively count against diagnoses that don't produce them. If you select several symptoms that genuinely contradict each other (say, a true powdery coating alongside rust bumps and spider-mite webbing), the tool will honestly report low confidence rather than force a guess. Results are filtered to culprits relevant to your plant type, ranked by confidence (Strong / Possible / Weak Match), and include a first step to try — not just a name. Always confirm by close inspection before treating, and when the match is weak, treat it as a starting point rather than a final answer.
