Pruning methods: Use sharp, clean pruning shears to make cuts at a 45-degree angle, just above a healthy bud or branch junction. Remove dead, diseased, or broken branches, and cut back overgrown branches to encourage branching. Keep pruning to a minimum as this species of Salix does best when left in its natural state.
Propagation of Salix melanopsis Nutt. var. kronkheittii L. Kelso
Salix melanopsis Nutt. var. kronkheittii L. Kelso, commonly known as the dusty desert willow, can be propagated through several methods. Some of the most popular propagation techniques include:
Seed Propagation
Propagation via seeds is one of the easiest and most popular methods for the dusty desert willow. Collect ripe seeds in autumn or early winter when the capsules begin to open. Clean the seeds and soak them in water overnight. Then, put them in moist sand and keep them at a temperature range of 68-77°F (20-25°C). Germination usually takes between 1-3 weeks. Once the seedlings have developed leaves, they can be transplanted into individual containers.
Cuttings Propagation
The dusty desert willow can also be propagated via cuttings. Take cuttings in late summer or early fall. Choose a healthy stem with a diameter of about 0.15-0.5 inches (4-12 mm) and a length of at least 4 inches (10 cm). Remove the leaves and the lower part of the stem. Dip the base of the cutting in rooting hormone and put it in moist soil. Keep it in a warm, bright place and regularly water it. Roots should begin to form after about 4-5 weeks, and after 2-3 months, the cutting should have developed a strong root system and can be transplanted.
Grafting Propagation
Grafting is a technique commonly used to propagate the dusty desert willow. It involves joining a scion from a desirable plant onto a rootstock of another plant. Choose a healthy rootstock and a desirable scion of the same diameter as the rootstock. Make a diagonal cut on the scion and a corresponding cut on the rootstock. Join the two cuts together and wrap them with grafting tape. Keep the graft in a warm, bright place and regularly water it. If successful, the graft should have grown together after about 6-8 weeks.
