Troubleshooting
Bougainvillea spectabilis problems — and how to fix them
Bougainvillea spectabilis (Bougainvillea spectabilis) 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.
Leaves but no bracts
Too little light, overwatering or too much nitrogen — give maximum sun, keep it on the dry side and feed high-potash.
Sudden leaf drop
Cold draughts, sharp temperature swings or letting it dry out completely, common when moving plants indoors for winter.
Yellowing leaves
Usually overwatering and poor drainage, or sometimes magnesium/iron deficiency on alkaline soils.
Frost damage
Even a light frost blackens growth; protect or bring under cover before temperatures fall to freezing.
