Based on plant wilting, dying back, or looking unwell on the lower leaves with moist soil, the closest match is root rot. Confirm it against the actual plant: Lavender can suffer root rots leading to premature death; it won't tolerate shade, wet, freezing or heavy soils.
- This is a symptom-pattern match from your written description, not a lab diagnosis. If the plant is collapsing over days (not weeks), treat it as the worst plausible cause until ruled out.

- 2.Improve drainage immediately — move containers under cover, raise beds, or add grit; cut back on watering. Severely rotted plants may not recover, but catching it early saves most.
- 3.Collapsing fast (days, not weeks)? Photograph it and check with your county extension before treating

Why
What to do: Improve drainage immediately — move containers under cover, raise beds, or add grit; cut back on watering. Severely rotted plants may not recover, but catching it early saves most.
- A symptom tree ranks causes by how well your conditions match each cause's known pattern — the distinguishing signs are how you confirm it on the actual plant, not a lab result.
- Most leaf problems trace to water, weather, or common leaf-spot fungi; true plant-killers are rarer but worth ruling out first.
When this doesn't apply
- If the plant is collapsing fast (days, not weeks), treat it as the most severe possibility on the list until proven otherwise.
- Multiple symptoms at once usually means the top cause here plus plain stress — fix watering first, then re-check.
