Anthurium andraeanum 'Rubrum' problems — and how to fix them
Anthurium andraeanum 'Rubrum' (Anthurium andraeanum 'Rubrum') 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.
Dull or browning red spathes
Direct sun and low humidity degrade colour, while old blooms green naturally; provide bright indirect light and trim spent flowers.
Brown leaf tips
Low humidity or mineral buildup from tap water; raise humidity and flush the mix with low-mineral water.
No new flowers
Too little light or over-feeding with nitrogen; relocate to brighter light and feed a balanced or phosphorus-rich formula.
Yellowing leaves and mushy stems
Overwatering and poor drainage cause root rot; repot into chunky aroid mix and allow the surface to dry between waterings.
