Propagation of Mesembryanthemum horridum Koutnik & Lavis
Mesembryanthemum horridum Koutnik & Lavis can be propagated from both seeds and cuttings.
Propagation from Seeds
Seeds of Mesembryanthemum horridum Koutnik & Lavis can be sown in well-draining soil during the spring season. The seeds need to be surface sown and covered with a thin layer of soil. The soil should be kept moist, but not too wet, until the seeds germinate. Germination usually occurs within 2-3 weeks. Once the seedlings are large enough, they can be transplanted into individual pots. The young plants should be kept in a bright spot, but protected from direct sunlight until they are well established.
Propagation from Cuttings
Cuttings of Mesembryanthemum horridum Koutnik & Lavis can be taken during the spring season. The cuttings should be about 10 cm long and taken from the stem tips. The leaves on the lower half of the stem should be removed, and the cutting should be dipped into a rooting hormone powder. The cutting can then be inserted into a well-draining soil mix. The soil should be kept moist, and the cutting should be kept in a bright spot, but protected from direct sunlight. The cutting should root within 2-3 weeks. Once the cutting is well established, it can be transplanted into an individual pot.
Both propagation methods can result in strong and healthy plants that can be enjoyed for many years.
