Propagating Cape Sundews from Seed: Avoiding Common Pitfalls

A grower in Zone 7a sowed Drosera capensis seeds on rinsed long-fiber sphagnum moss in standing water, but the medium stayed too wet. The expert advises lowering the water level to ¼ pot depth and misting the surface 1–2 times daily instead. Seeds should be surface-sown on granulated moss (to prevent seeds from sinking into gaps) and kept moist but not waterlogged.

Optimal Germination Conditions

• Temperature: 65–75°F preferred, but tolerates up to 80°F.
• Light: 8 hours of sun when available; bright indirect light otherwise.
• Humidity: High, stable humidity aids germination.
• Patience: Seeds sprout in 2–6 weeks.

The expert notes that long-fiber sphagnum is acceptable, but granulating the surface improves seed contact. With thousands of seeds per packet, D. capensis is forgiving – even suboptimal setups often yield some seedlings. The key is avoiding waterlogging, which promotes algae and fungal issues.
