Seed Propagation
Seeds of Rafnia angulata Thunb. subsp. montana G.J.Campbell & B.-E.van Wyk are small and light, and a single plant can produce several hundred seeds. Seed propagation can be done by:
- Sowing seeds directly outdoors in fall or spring. The soil should be well-drained and fertile with a pH of 6.0 to 7.0.
- Seeds can be started indoors in pots or trays during spring. The seeds should be sown in a well-drained potting mix and kept moist until germination.
- Transplant the seedlings to the garden once the danger of frost has passed. They should be planted 6 to 12 inches apart in a sunny to partly shaded location.
Cutting Propagation
Rafnia angulata Thunb. subsp. montana G.J.Campbell & B.-E.van Wyk can be easily propagated by stem cuttings. The steps to follow are:
- Take cuttings of 5 to 8 inches long from the parent plant during the growing season.
- Remove the lower leaves and dip the cut end in rooting hormone powder.
- Place the cutting in a well-drained rooting medium such as coarse sand or a peat and perlite mix.
- Water the cuttings and cover them with a plastic bag to maintain humidity.
- Place the cuttings in a bright but indirect light and keep the rooting medium moist by misting regularly.
- The cuttings should root in 4 to 6 weeks and can be transplanted in the garden after the danger of frost has passed.
Propagation of Rafnia angulata Thunb. subsp. montana G.J.Campbell & B.-E.van Wyk through cuttings is faster and easier than seed propagation and results in more uniform plants.
