Green-spotted Billbergia problems — and how to fix them
Green-spotted Billbergia (Billbergia chlorosticta) is generally low-drama, but a few issues come up again and again. Here is what each one looks like, why it happens, and the fix.
Scale insects
Brown or pale waxy bumps on leaf surfaces and bases, leaving sticky honeydew and sooty mould; treat by wiping with alcohol-soaked cotton and applying neem oil, and improve air circulation around the plant.
Leaf colour fade
Insufficient light causes the distinctive cream-white spotting to disappear, leaving dull plain green leaves; move to a brighter position with filtered light and colour should return within weeks.
