What are Desert Willows?

Desert Willows (Chilopsis linearis) are small, multi-trunked trees that can grow up to 30 feet tall with a spread of 15-20 feet. They are native to the southwestern United States, Mexico, and parts of South America. The tree has leaves resembling willows and flowers that are trumpet-shaped.

Why is Pruning Necessary?

Pruning your desert willow promotes healthy growth and enhances its aesthetic appeal. A well-pruned tree will have an open canopy, allowing sunlight to penetrate to the lower branches and encouraging new growth. Additionally, pruning can help prevent proper circulation of air, minimizing the risk of disease and pests infestations.
