Troubleshooting
Raven ZZ Plant problems — and how to fix them
Raven ZZ Plant (Zamioculcas zamiifolia 'Raven') 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.
Yellow leaves from overwatering
The most common issue. Yellow, mushy stems at the base indicate root or rhizome rot. Remove the plant from the pot, cut away rotted tissue, allow to dry for a day, and replant in fresh dry compost. Drastically reduce watering frequency.
Slow colour darkening
New leaves emerge green and take several weeks to mature to near-black — this is normal for the Raven cultivar. Ensure the plant receives adequate indirect light, as very low light can slow the darkening process.
Scale insects
Flat, waxy brown bumps on stems and leaf undersides. Wipe off manually with a cotton bud dipped in rubbing alcohol and treat with a systemic insecticide or neem oil for persistent infestations.
