Slim-Flowered Portea problems — and how to fix them
Slim-Flowered Portea (Portea leptantha) 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.
Stagnant tank water
Flush the central cup with fresh water every 1-2 weeks to prevent bacterial growth and mosquito breeding.
Leaf-tip browning
Indicates low humidity or use of chlorine-heavy tap water; switch to rainwater or let tap water stand before use.
Scale and mealybugs
Inspect leaf axils regularly; treat infestations promptly with insecticidal soap or a systemic insecticide.
Overwatering root zone
The soil medium should not stay constantly wet; allow the top layer to dry between waterings.
Cold draughts
Temperatures below 12°C for prolonged periods cause leaf damage; keep away from cold windows in winter.
