Cultivation and Uses
USDA hardiness zones: 9-12.

Sun: Full sun.
Water after becoming established: Monthly, deeply, at the drip line and away from the trunk to encourage sideways root growth. In the hottest months of the year, deep water twice a month.
Soil: Well drained, pH 6.1-8.5 (slightly acidic to alkaline), this tree is subject to root rot with excessive moisture. It is very saline tolerant. *Do not use a nitrogen fertilizer.
First Year Care: Water weekly until one month before frost. Use a double-dike system: two concentric dirt dike rings, the first at the drip line, the second two feet outside the first. Move the dikes outward every year for the first five years. Never water at the trunk or the roots will not grow away from it.
Prune: To force an upright tree shape.
Litter: Seedpods and leaves.
Propagation: Seed. This tree reseeds itself in favorable conditions.
Pests: A mistletoe infection is possible when it receives insufficient water during drought.
Uses: Ornamental, filtered shade.

Comments
This tree is a member of the Legume family (Leguminosae). Its roots must be encouraged to grow sideways away from the trunk, through proper watering, to form a wider root system. This makes the tree more drought tolerant and keeps it from being toppled by strong winds.
