Propagation of Salsola pestifer A. Nels.
Salsola pestifer A. Nels. can be propagated through seeds and cuttings. However, it is mainly propagated through seeds.
Propagation through Seeds
Seeds of Salsola pestifer A. Nels. can be collected from the plant after maturity. The seeds should be sown in well-drained soil. Before sowing, the seeds should be scarified to break their hard seed coat and to aid in germination. Scarification can be done by rubbing the seeds with sandpaper or by soaking them in hot water for a few minutes. The seeds should be then sown at a depth of 1-2cm and kept moist until they germinate, which usually takes around 1-2 weeks.
Propagation through Cuttings
Cuttings can be taken from Salsola pestifer A. Nels. during the active growing season. The cuttings should be taken from young, healthy plants and should be about 10-15cm long. The leaves on the lower half of the cutting should be removed, and the cutting should be allowed to dry for a few hours. Once the cutting has callused, it can be planted in well-drained soil. The soil should be kept moist until the cutting establishes roots, which usually takes around 2-3 weeks.
