Two-Spiked Billbergia problems — and how to fix them
Two-Spiked Billbergia (Billbergia distachia) 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.
Stagnant cup and fungal rot
Still water in the central tube in warm conditions breeds bacteria and can lead to crown rot. Flush and refresh the cup regularly and ensure good air circulation around the plant.
Green foliage without colour
In low light the leaves remain plain dark green and the reddish tints do not develop. Increase brightness (bright indirect or a few hours of gentle morning sun) to restore ornamental coloration.
Mealybugs
The tubular rosette and leaf axils provide sheltered hiding spots. Inspect regularly and treat with alcohol on a cotton swab or a dilute neem-oil spray at the first sign of infestation.
