The desert willow is a deciduous, hardwood tree found in warm areas of the United States. The tree can grow between 15 and 30 feet in height with the same width. The desert willow branches do not hang like the weeping willow, instead pointing straight into the air. Desert willows produce a trumpet-shaped flower that is usually pink or dark burgundy in color. To prevent disease and aid in flower production, the desert willow requires pruning after the flowers have passed around Christmas time.
Remove dead or broken branches and limbs from the desert willow to improve appearance.
Cut away shooting branches that grow vertically from the main branch to encourage horizontal growth in the tree.
Prune small branches that are strong 1/4 inch above buds to encourage new bud growth.
Remove crossing branches, and prune excessive foliage from the canopy of the tree to allow sunlight into the trunk. Do not remove more than 30 percent of the canopy during the summer months if pruning is necessary, as this will burn the tree.
