Find the Cause Before You Treat the Symptom
Use the guided Problem Diagnoser when you do not know what is wrong. Choose the affected plant area, select what you can actually see, and compare the strongest evidence-based matches.
Problem Diagnoser
Show us what the plant is doing
You do not need to know the problem name. Start with the plant area that looks most affected, then add the visible pattern and supporting evidence.
Quick start by dominant symptom
Step 1 of 4
Where is the strongest problem?
Choose the area that gives you the clearest evidence. You can restart at any time.
Step 2 of 4
What can you actually see?
Select every pattern that is clearly present. Avoid guessing at a disease or pest name.
Step 3 of 4
Add the strongest supporting evidence
These details separate look-alikes. Choose one item in each group when you can.
What physical evidence is present?
Where is the pattern strongest?
Step 4 of 4
Your strongest pattern matches
How to read this: percentages are relative match scores based on your selections. They are not laboratory probabilities and do not prove a diagnosis.
Directory rule: An entry is a possibility to investigate, not a diagnosis made from appearance alone. The name becomes useful only when the plant pattern, physical evidence, growing history, and appropriate test support it.
