Troubleshooting
Purple-leaf Pepper problems — and how to fix them
Purple-leaf Pepper (Piper porphyrophyllum) 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.
Root rot
Caused by overwatering or poor drainage. Yellowing lower leaves and soft stems are early signs. Allow the top of the soil to approach dryness between waterings and ensure the pot drains freely.
Leaf scorch and bleaching
Direct sun exposure bleaches the dark variegation and scorches leaf edges. Move the plant back from the window or filter light with a sheer curtain.
Spider mites
Low humidity encourages spider mites. Check the undersides of leaves for fine webbing. Raise humidity, wipe leaves with a damp cloth, and treat with insecticidal soap or neem oil if infestation is confirmed.
