Troubleshooting
Betel Leaf problems — and how to fix them
Betel Leaf (Piper betle) is generally forgiving once you match its basics, but a few issues come up again and again. Here is what each one looks like, why it happens, and the fix.
Leaf spot (fungal)
Brown or yellow spots on leaves, particularly in stagnant humid air. Improve air circulation, avoid wetting foliage when watering, and treat with a copper-based fungicide. Remove affected leaves promptly.
Root rot
Overwatering or poorly draining soil leads to yellowing, wilting, and blackened roots. Repot into fresh well-draining mix; trim any rotten roots back to healthy tissue before repotting.
Whitefly
Whiteflies cluster on the undersides of leaves, weakening growth and depositing honeydew. Yellow sticky traps help monitor populations; treat severe infestations with insecticidal soap spray repeated weekly for 3–4 weeks.
