Troubleshooting
Sulawesi Wax Plant problems — and how to fix them
Sulawesi Wax Plant (Hoya sulawesiana) is generally low-drama, but a few issues come up again and again. Here is what each one looks like, why it happens, and the fix.
Root rot from overwatering
The most common cause of failure with this species; mushy stem base and rapid leaf yellowing indicate the roots are rotting. Remove from pot, trim dead roots, allow to dry out, and repot in fresh fast-draining mix — water much less frequently going forward.
Slow growth and reluctance to flower
H. sulawesiana is uncommon in cultivation and can be a slow establisher; insufficient light is the most frequent reason for stunted growth and no blooms. Move to the brightest indirect spot available and ensure temperatures stay above 18°C year-round.
