Troubleshooting
Carnival goldfish plant problems — and how to fix them
Carnival goldfish plant (Columnea 'Carnival') 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.
Bud drop
Buds fall prematurely when the plant is moved, subjected to cold draughts, or exposed to low humidity. Once flower buds appear, keep the plant in place and maintain humidity above 55%.
Leaf yellowing
Yellow lower leaves usually indicate overwatering or cold root temperatures. Ensure the potting mix drains freely and the plant is kept above 15 °C. If roots are brown and mushy, repot into fresh medium after trimming rotten roots.
Mealybugs
Mealybugs cluster in leaf axils and along stems, leaving white waxy deposits. Remove with a cotton swab dipped in rubbing alcohol and follow with repeated neem oil sprays at weekly intervals until absent.
