Troubleshooting
Costa Rican Goldfish Vine problems — and how to fix them
Costa Rican Goldfish Vine (Columnea consanguinea) 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.
Loss of red leaf markings
The translucent red markings are most vivid when sunlight filters through the leaves. In very low light, the markings become dull. Move to a brighter (indirect) position to restore the stained-glass effect.
Root rot in waterlogged conditions
Despite preferring moderate moisture, roots rot quickly in poorly drained soil. Ensure the potting mix is porous and the pot has effective drainage. Water in the morning so excess can evaporate.
Scale insects
Brown scale can establish along stems, causing sticky honeydew and yellowing leaves. Scrape off with a soft brush, wipe with rubbing alcohol, and treat with a systemic insecticide or horticultural oil for persistent infestations.
