Troubleshooting
White Rain Lily problems — and how to fix them
White Rain Lily (Zephyranthes candida) 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.
Failure to bloom
The key trigger is a dry spell followed by watering or rain. If the plant stays evenly moist all summer, flowers may not appear. Allow the soil to dry in late summer then water well.
Bulb overcrowding
Over time, dense clumps flower less. Divide every 3-4 years in early spring, replanting bulbs 5-7 cm deep.
Slug damage
Emerging flower buds can be eaten by slugs. Use physical barriers or organic slug pellets (ferric phosphate).
Frost sensitivity
In USDA zones below 7, lift bulbs before first frost and store frost-free. Mulch heavily to try for in-ground overwintering in zone 7.
Narcissus fly
The bulb fly larva can infest bulbs of Amaryllidaceae members. Remove infected bulbs; inspect at lifting time.
