Avocado Tree Problem Checker
Choose the symptom you can see, add a little context about your tree, and the checker returns the possible causes worth investigating, what to check first, and what to do next.

About the avocado tree problem checker
Avocado symptoms overlap heavily. Yellow leaves can mean overwatering, iron shortage, cold soil or simple age. Brown tips can mean salt accumulation, dry air or underwatering. Because of that, this tool never claims a diagnosis — it narrows the field and tells you which check separates one cause from another.
The most valuable step is almost always the same: look at the root zone. Dig a finger a few centimetres into the soil before you change anything, because water at the roots explains more avocado problems than every other cause combined.
How this tool works
- 1Pick the symptom that matches what you are seeing.
- 2Add tree age, origin, container or ground, light, watering and drainage.
- 3Causes are ranked by how well they fit your specific answers, each with a concrete check.
How to read your result
Possible causes, in order of fit
The top cause is the one that best matches your inputs. It is a starting point for investigation, not a verdict.
Do the checks before the treatments
Feeding a waterlogged tree makes things worse. Confirm what is happening at the roots first.
Some damage will not reverse
Leaves that have already browned do not turn green again. Judge recovery by new growth, not old leaves.
Worked example
Yellow leaves on a potted tree watered every two days in a pot without drainage holes puts overwatering and poor drainage at the top, with the finger test as the first check.
