How to Propagate Rattles?
For rattles, the primary propagation method is by seed sowing, as they do not root easily from cuttings or divide well. Key factors for successful seed propagation include well-draining soil, moderate light exposure, and a temperature range of 15-20°C. Pre-chill seeds before sowing to break dormancy. Sow seeds in autumn, allowing winter's cold to stratify them naturally, or stratify artificially for 3-6 weeks at 4-5°C before spring sowing. The general difficulty level is moderate due to the need for cold stratification. Steps: 1) Collect seeds when they're mature in late summer. 2) If artificially stratifying, mix seeds with moist sand and refrigerate for 3-6 weeks. 3) Sow seeds on the soil surface in pots or directly in the garden after last frost. 4) Lightly press seeds into the soil but do not cover as light aids germination. 5) Keep the soil consistently moist until germination occurs, which can take several weeks.
