Propagation methods of Salix elaeagnos Scop.
Salix elaeagnos Scop. can be propagated through both sexual and asexual methods.
Sexual propagation
Salix elaeagnos Scop. can be propagated through seed germination. The seeds should be collected in autumn when they are mature and stored in a cool and dry place until spring when they can be sown. The seeds need to be stratified for several weeks before sowing, which means they need to be exposed to low temperatures to break dormancy. The best time to sow the seeds is in early spring when the weather is mild. The seeds should be sown in a well-draining soil mix, and kept moist until they germinate, which can take several weeks to several months.
Asexual propagation
The most common asexual method of propagation for Salix elaeagnos Scop. is through hardwood cuttings. The best time to take cuttings is in the winter when the plant is dormant. Cuttings should be taken from young and healthy twigs, around 20-25 cm long with a diameter of 0.5-1 cm. The lower part of the cutting should be treated with rooting hormone and planted in a rooting medium, such as sand and peat moss. The cuttings should be kept in a warm and moist environment, but not wet, until they develop roots, which can take several months.
Salix elaeagnos Scop. can also be propagated through softwood cuttings. The best time to take cuttings is in the spring or early summer when the plant is growing actively. Cuttings should be taken from young and healthy twigs, around 10-15 cm long with leaves attached. The lower part of the cutting should be treated with rooting hormone and planted in a rooting medium, such as sand and peat moss. The cuttings should be kept in a warm and moist environment, but not wet, until they develop roots, which can take a few weeks to a few months.
