Troubleshooting
Kucyniak's Columnea problems — and how to fix them
Kucyniak's Columnea (Columnea kucyniakii) 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 overwatering
The most frequent killer — stems collapse and roots turn brown and mushy. Always use a free-draining epiphyte mix, ensure drainage holes are clear, and do not water again until the top of the compost has dried out.
Failure to flower
Insufficient light is the primary cause; move the plant closer to a bright window or add supplemental grow lighting. A slight temperature drop of 3–5 °C at night in autumn also helps trigger bud set.
Spider mites
Low humidity encourages spider mite infestations, which appear as fine webbing on stems and yellowing, stippled leaves. Increase humidity and treat with insecticidal soap or neem oil spray.
