Ephedra sinica Seed Sowing & Care Quick Overview Ephedra sinica prefers full sun and dry, sandy soils. Proper pre-treatment and a sandy, well-drained sowing medium improve germination and seedling vigor. Seed Pre-treatment Soak: 48 hours in willow-tip tea or plain, pure water kept in the fridge. Substrate & Sowing Medium: Very sandy potting mix—about 50% coarse, sharp sand (builder’s sand), not beach sand. Sowing Depth: Sow soaked seeds on the surface, then cover to a final depth of 1 inch. Planting deeply increases germination rates and provides support against flopping and damping-off. Firming: Tamp the surface securely after covering. Moisture, Temperature & Germination Moisture: Keep evenly moist (not waterlogged) until germination. Temperature: Warm medium; greenhouse or under propagation lights is ideal. Germination Time: 10–30 days under warm, controlled conditions.
