Troubleshooting
Orange Star problems — and how to fix them
Orange Star (Ornithogalum dubium) 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.
Bulb rot from overwatering
The most common indoor problem; water only when the top layer of soil is dry and ensure the pot has good drainage holes.
Failure to re-bloom
Usually due to skipping summer dormancy; let the plant dry out completely after flowering and resume watering in autumn for repeat blooms.
Aphids
Infest flower stems in spring; remove with insecticidal soap or a strong water spray.
Botrytis
Grey mould on spent flowers or leaves in cool, damp conditions; remove dead plant matter promptly and improve air circulation.
Leggy growth
Result of insufficient light; move to the brightest available position or supplement with a grow light.
