Seed Propagation
Seeds are the most common method of propagating Salix arctica R. Br. ex Richards. The seeds can be harvested in late summer or early fall when the capsules are dried and released. The seeds should be sown immediately after collection or kept in a cool and dry place until sowing. The best time to sow the seeds is in early spring, and they should be sown in a well-draining soil mix at a depth of 1-2 cm. The seedlings should be kept in a warm and moist place until they germinate, which usually takes 1-2 months.
Cuttings Propagation
Another propagation method for Salix arctica R. Br. ex Richards. is cuttings. Hardwood cuttings are taken in the fall or winter from mature plants. The cuttings should be approximately 20-30 cm in length, and the leaves should be removed from the lower half of the stem. The cuttings should be planted in a well-draining soil mix, and the top of the cuttings should be covered with a plastic bag to maintain moisture levels. The cuttings usually take 1-2 months to root.
Division Propagation
Division propagation is a method of propagating Salix arctica R. Br. ex Richards. by dividing the root ball of mature plants. This method should be done in the fall or spring when the plant is dormant. The plant should be dug up, and the root ball should be carefully divided into several sections, each containing a portion of the stem and several roots. The divided sections should be immediately planted in a well-draining soil mix and kept moist.
In conclusion, Salix arctica R. Br. ex Richards. can be propagated through seeds, cuttings, or division. Each method has its own advantages and disadvantages, and the choice of method depends on the availability of resources and the desired outcome.
