Troubleshooting
Amethyst Porroglossum problems — and how to fix them
Amethyst Porroglossum (Porroglossum amethystinum) 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.
Rapid root fill and pot-bound stress
This is a vigorous grower that fills small containers quickly. A pot-bound plant shows reduced new growth and may stop flowering. Check the root system annually and repot into a slightly larger container or divide when roots fill the pot.
Botrytis flower blight
Spent flowers left on the plant in humid, still air can develop Botrytis grey mould that spreads to leaves. Remove fading inflorescences promptly and ensure a gentle air current circulates around the plant at all times.
Mineral build-up on sphagnum
Sphagnum retains fertiliser and water mineral salts, causing white crust and eventual root tip browning. Use only low-mineral water and flush the medium thoroughly every 3–4 waterings to leach accumulated salts.
