Blood-red Guzmania problems — and how to fix them
Blood-red Guzmania (Guzmania sanguinea) 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.
Failure to colour up (inner leaves stay green)
Insufficient light or incorrect temperatures can prevent the inner leaf flush — ensure the plant receives bright indirect light and temperatures above 18°C to trigger colouring.
Stagnant cup water and crown rot
Water sitting too long in the tank becomes anaerobic and breeds bacteria; flush and replace cup water monthly and use only clean rainwater or distilled water.
