Goldfish Plant Pruning: Winter Rest Period Required

Why Prune Now—Even Though It’s Growing

Goldfish plants (Nematanthus) need a cool, dry rest from November to March to set flower buds for summer. Continued winter growth disrupts this cycle.

Action Plan

1. Prune hard now: Cut long stems back to a few inches above soil. Painful but necessary.
2. Rest regime (Nov–Mar): Keep cool (55–65°F), water only to prevent wilting (soil very dry), stop fertilizing.
3. Resume active care in April: Warm spot, moist soil, monthly half-strength fertilizer, south/west window.
4. Expect flowers July–September.

Why This Works

The rest period mimics the natural dry season. Without it, the plant grows vegetatively but won’t bloom well.
