Troubleshooting
Tahitian Gardenia problems — and how to fix them
Tahitian Gardenia (Gardenia taitensis) 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.
Bud drop
The most frustrating issue — caused by low humidity, inconsistent watering, temperature fluctuations, or moving the plant once buds form. Stabilise conditions and maintain humidity above 60%.
Whitefly
Tiny white insects on leaf undersides sap plant vigour and excrete honeydew that causes sooty mould. Treat with yellow sticky traps, insecticidal soap, or neem oil spray repeated every 7–10 days.
Root rot
Overwatering in poorly draining soil causes roots to turn brown and mushy. Remove from the pot, trim dead roots, dust with cinnamon or sulphur, and repot into fresh, well-draining mix.
