Troubleshooting
Crimson Portea problems — and how to fix them
Crimson Portea (Portea kermesina) 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.
Root rot from waterlogged soil
The most common killer. Ensure the pot has drainage holes and never allow the plant to sit in standing water. Use a fast-draining mix and err on the side of dry between waterings.
Scale insects on leaf bases
Armoured or soft scale can collect at the base of the tight leaf rosette. Wipe off with a cotton swab dipped in isopropyl alcohol or treat with neem oil solution.
Leaf tip browning
Caused by low humidity, fluoride in tap water, or salt build-up from fertiliser. Flush the soil periodically, switch to rainwater or filtered water, and boost ambient humidity.
