Texas Honey Mesquite
Prosopis glandulosa
A spreading native mesquite that provides generous shade and critical habitat for bees, birds, and wildlife.
Cold hardy to near 0°F, a very heat- and frost-tolerant native from low to high desert.
AMWUA Notes
Deep infrequent watering builds wind-firm roots; overwatering causes hazardous fast growth prone to storm breakage.
Care Guide
Deep-soak every two weeks in summer to drive growth, but favor deep infrequent watering to anchor roots and prevent blow-over.
Prune in late winter to build a strong scaffold and thin the canopy to reduce wind-throw; wear gloves for the variable thorns and avoid over-thinning.
No fertilizer needed; overwatering and feeding produce weak, storm-prone growth on this nitrogen-fixer.
Giant mesquite bug (cosmetic) and mistletoe.
Yellow-green catkins in spring with heavy allergen pollen; deciduous in winter with messy leaf and pod drop.
Soil, Feeding & Propagation
Adaptable, well-draining native soil; tolerates caliche, clay, rocky ground, and alkaline pH 7.5–8.5
Needs moderate soil.
None — thrives in lean desert soil without fertilizer.
Grown easily from scarified seed; self-sows readily
25–30 ft
Deep taproot plus aggressive water-seeking laterals; keep 20+ ft from pools, foundations, sewer, and paving
Placement Tips
- •Broad 30 ft canopy for shade; give it 20+ ft from structures and pools because of pods, variable thorns, and heavy pollen.
- •Deep taproot; stake and thin young trees so they resist monsoon winds.
- •Not pool friendly due to messy litter and pollen; best in native or large-lot landscapes.
- •Full sun; a keystone wildlife tree.
