Goodding's willow is a fast-growing native tree of the desert Southwest, forming the backbone of riparian corridors along rivers, streams, and irrigation channels from California to western Texas and into northwestern Mexico. It is one of the most ecologically significant trees in arid western landscapes, providing dense canopy and wildlife cover in areas where shade is scarce.
It establishes readily from hardwood cuttings pushed directly into saturated streambank soil and roots aggressively wherever it can reach the water table. Well suited to pond margins, bioswales, and stream restoration projects, it tolerates periodic flooding and brief surface drought once established. Basal suckering is vigorous; in open ground without management it forms multi-stemmed thickets. Prefers a permanent or seasonal high water table and neutral to slightly alkaline soil.
Like other willows, the bark contains salicin, the glycoside that led to aspirin's development. Indigenous peoples of the Sonoran Desert region used willow bark preparations for pain and fever. The dense canopy provides essential nesting habitat for the federally endangered southwestern willow flycatcher (Empidonax traillii extimus), making it a priority species in stream restoration work.

Willow Scab
Olive-brown to black lesions appear on young leaves within days of bud break, causing rapid curling and leaf drop. Shoot tips blacken and die back. Dark, sunken lesions develop on current-season stems, and salmon-colored spore masses may be visible on infected tissue during humid weather.
Rake and destroy all fallen leaves and infected shoot tips each autumn. Apply a copper-based fungicide or myclobutanil at bud swell, then again at bud break. In persistently wet springs, repeat every 10–14 days until new shoot growth hardens off. Improve canopy airflow through selective pruning and avoid overhead irrigation.
Cytospora Canker
White or blue-white pitch masses ooze from bark on lower branches and the trunk. Affected branches die back progressively from the tip inward; bark beneath the resin is discolored brown and may have a resinous, sunken appearance.
Prune infected branches well below the canker margin into healthy wood and destroy all cuttings. Sterilize pruning tools with 70% isopropyl alcohol between each cut. No effective fungicide is available; prevent recurrence by avoiding drought stress, soil compaction, and mechanical bark injury.
Rust
Orange to brown raised pustules on the undersides of leaves, with yellow spotting on the upper surface. Heavy infections cause leaves to yellow and drop.
Remove and destroy infected leaves. Avoid overhead watering and improve air circulation. Apply a sulfur or copper-based fungicide if it spreads. Clear plant debris in fall.
Armillaria Root Rot
Thinning, yellowing canopy with progressive dieback; white, fan-shaped mycelial mats visible beneath bark at or just below the soil line; honey-colored mushroom clusters appearing at the trunk base or on surface roots in autumn.
No chemical cure exists. Improve drainage and avoid any injury to roots or trunk. Remove severely infected trees along with as much root material as possible. Do not replant susceptible species in the same spot.
