Troubleshooting
Black Gold Goldfish Plant problems — and how to fix them
Black Gold Goldfish Plant (Nematanthus 'Black Gold') 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
The most common problem — caused by overwatering or poorly drained soil. Ensure the pot has drainage holes and the top few centimetres dry out before re-watering. Remove mushy roots and repot into fresh, drier mix if rot is found.
Bud drop
Cold drafts, sudden temperature changes, or moving the plant once buds have formed causes bud drop. Keep in a stable warm position away from air-conditioning vents and cold windows.
Failure to flower
Insufficient light or keeping the plant too warm year-round prevents bloom initiation. A brief cool-down period (to around 15°C) in late autumn followed by increased light in late winter can trigger the next flush of flowers.
