Propagation of Salix fragilis L. var. fragilis
Salix fragilis L. var. fragilis, commonly known as crack willow, is a deciduous tree that is native to Europe and Western Asia. It is a hardy tree that can grow in a wide range of soil types, including wet soils. Propagation of Salix fragilis L. var. fragilis can be done through several methods, as described below:
Propagation by Seeds
Propagation by seeds is the easiest method of propagating Salix fragilis L. var. fragilis. The seeds should be collected from mature trees in late summer or early fall. The collected seeds should be stored in a cool and dry place until they are ready to be sown. In late winter or early spring, the seeds should be sown in a seed tray or pot containing a moistened mixture of peat moss and sand. The seeds should be covered lightly with soil and placed in a warm, bright location. The seeds should germinate in 2-3 weeks and then can be transplanted to individual pots or directly to the ground.
Propagation by Cuttings
Propagation by cuttings is another viable method of propagating Salix fragilis L. var. fragilis. Hardwood cuttings should be taken from mature trees in late fall or early winter. The cuttings should be about 30 cm long and should be taken from the previous year's growth. The lower leaves should be removed, and the cuttings should be dipped in rooting hormone powder. The cuttings should be planted in a pot filled with a mixture of sand and peat moss and placed in a bright location. The cuttings should be kept moist and should root in 2-3 months. The rooted cuttings can be transplanted to individual pots or directly to the ground.
Propagation by Layering
Propagation by layering is an effective method of propagating Salix fragilis L. var. fragilis. In early spring, a low branch of a mature tree can be bent and partially buried in soil. The branch should be attached to the ground with a wire or stake. The branch should be kept moist and should root in 2-3 months. Once rooted, the branch can be cut from the mother plant and transplanted to an individual pot or directly to the ground.
By following these propagation methods, one can produce healthy and vigorous Salix fragilis L. var. fragilis trees, which will make an attractive addition to any garden or landscape.
