How to Grow Desert Willow
Chilopsis linearis
Desert willow is a graceful deciduous small tree native to the US Southwest, producing orchid-like tubular flowers in shades of pink, purple, burgundy, and white from late spring through autumn. It attracts hummingbirds and tolerates extreme heat and drought once established. Plant in full sun with well-drained soil. It is one of the last trees to leaf out in spring and among the first to drop leaves in autumn. Minimal water needed once established; overwatering shortens its lifespan.
Yearly Lifecycle
Care Essentials
Desert willow rarely needs fertiliser. In very poor soils, a light application of balanced fertiliser in spring during the first two years is sufficient. Established trees need no feeding.
Watch For
- Root rot from overwatering
- Aphids on new growth in spring
- Catalpa sphinx moth caterpillars
Care Requirements
Light
Full sun, hot position
Requires maximum sunlight for best flowering. Tolerates extreme heat. One of the last trees to leaf out in spring, needing warmth to break dormancy.
Watering
Minimal once established
Deep water every two weeks during the first year. After establishment, reduce to monthly or stop entirely where rain occurs. Overwatering shortens lifespan.
Fertilizing
Rarely needed
Desert willow thrives in poor soils without feeding. In very depleted soils, a light balanced fertiliser in spring during the first two years is sufficient.
Pruning
Shape while dormant in late winter
Prune in late winter to remove crossing branches and shape the canopy. Can be trained as single-trunk or multi-trunk. Responds well to pruning.
