Drought tolerant: Yes.
Sun: Full sun.
Water after becoming established: Deep water every two months
Always water past the drip line of the tree and away from
the trunk to encourage lateral root development. Water encourages
crown growth and mesquites without sufficiently wide roots can be
blown over by strong winds.
Soil: Well drained, dry, low in organic content,
pH 6.6-8.5 (neutral to alkaline). *Do not use a nitrogen fertilizer.
Prune: In winter, remove lowest branches to train into a tree.
Also thin crown by removing any inward- or downward-pointing branches.
Do not prune more than 20% of crown or root growth will be slowed.
Without periodic thinning, heavy wind damage may occur.
This is a high maintenance tree.
Litter: Moderate to high, depending on cultivar. Seedpods may
Uses: Ornamental, shade.
This tree is sometimes sold as South American Hybrid Mesquite.
Several cultivars are bred by nurseries and vary in
appearance and behaviour.
