Diagnosis
Diagnose: Mint Yellow Leaves
Follow these steps to identify and confirm the problem.
- Leaf texture and soil condition separate the common causes
- Soft yellow lower leaves above a heavy wet root ball point toward poor root aeration, while crisp margins and a light pot support drought stress. If moisture looks normal, use leaf age next, then inspect the undersides for dusty rust pustules, fine stippling, webbing, or insects.
