Troubleshooting
Bellina Moth Orchid problems — and how to fix them
Bellina Moth Orchid (Phalaenopsis bellina) 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
The most common killer of this species. Caused by overwatering or a soggy, broken-down medium. Roots turn brown, soft and slimy and the medium smells sour. Repot into fresh, airy bark, trim dead roots and water more sparingly.
Bud blast (buds drop before opening)
Developing buds yellow and fall off, usually from sudden temperature swings, draughts, low humidity, or inconsistent watering. Keep conditions stable while the plant is in spike.
Crown and leaf rot
Water trapped in the central crown or leaf axils overnight invites bacterial and fungal rot, which can be fatal. Water in the morning and blot moisture from the crown; ensure good airflow.
Sunburn
Direct sun produces bleached, scorched or sunken tan patches on the leaves. Move to bright but filtered light or add a sheer screen.
Failure to bloom
Often too little light or no day-night temperature difference. Provide bright indirect light and a slight nighttime temperature drop to encourage spiking.
Pests (mealybugs, scale, mites)
Sap-sucking mealybugs and scale hide in leaf axils and under leaves; mites cause stippling in dry air. Wipe off and treat with horticultural soap or oil, repeating as needed.
