Propagation of Salix bebbiana Sarg.
Salix bebbiana Sarg., commonly known as Bebb Willow or long-beaked willow, is a tree species that is native to North America. It is a deciduous plant that can grow up to 30 feet tall. Bebb Willow is usually propagated by cuttings or by seeds.
Propagation by Cuttings
Propagation by cuttings is the most common method of propagating Bebb Willow. The best time to take cuttings is during the dormant season, from late fall to early spring when the plant is not actively growing. The cuttings should be taken from healthy and disease-free branches. Cuttings should be about 6-8 inches long and about ¼ inch in diameter. The basal cut should be made just below a node, while the upper cut should be made about ½ inch above the last bud. Remove the leaves from the bottom 1-2 inches of the cutting to expose the cambium layer. Dip the cut end in rooting hormone and plant it in moist soil. Water the cutting well and keep it in a shaded location until roots form, usually within six to eight weeks.
Propagation by Seeds
Propagation by seeds is another way to propagate Bebb Willow. Seeds should be collected from mature, healthy, and well-established trees. The best time to collect the seeds is in late summer to early fall when the capsules are mature and releasing the seeds. To facilitate germination, the seeds should be subjected to cold stratification for about 60 days prior to sowing. Sow the seeds about ¼ inch deep in a well-draining soil mixture in pots or in a nursery bed. Keep the soil moist and the temperature at around 70°F. Germination usually occurs within three weeks. Seedlings should be transplanted to their permanent location after they reach a height of 6-8 inches.
