Related Columnea problems — and how to fix them
Related Columnea (Columnea consanguinea) 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.
Fungal leaf spots
The large leaves are vulnerable to fungal spotting when misted in cool or poorly ventilated conditions; improve air circulation and avoid wetting foliage — use a pebble tray for humidity instead.
Spider mites
Dry air promotes spider mite infestations visible as fine webbing and pale stippling; maintain humidity above 60% and treat with neem oil or insecticidal soap applied to both leaf surfaces.
