Troubleshooting
Double Pinwheel Flower problems — and how to fix them
Double Pinwheel Flower (Tabernaemontana divaricata 'Flore Pleno') 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
Flower buds falling before opening are usually caused by sudden temperature change, low humidity, irregular watering, or moving the plant while buds are forming. Stabilise conditions and keep soil evenly moist once buds appear.
Powdery mildew
White powdery coating on leaves in low-light, poor-airflow conditions. Improve ventilation, reduce overhead humidity, and treat with a diluted bicarbonate of soda spray or a sulphur-based fungicide. Remove heavily affected leaves.
Mealybugs
White cottony pests shelter in the dense double flower petals and leaf axils where they are hard to spot. Inspect blooms and axils regularly; treat with insecticidal soap or neem oil, applying carefully to avoid browning petals.
