Prosopis

These deciduous trees grow wild from the southeastern part of the U.S. to Chile. These trees are commonly known as Mesquite, Algarobe and Cashaw. Mesquites are suitable for growing in hot, dry climates because their taproots grow deeply in search of moisture (as much as 50 to 60 feet deep on mature desert trees) enabling them to withstand drought and high temperatures. P. glandulosa (Honey Mesquite) grows from 15 to 30 feet high depending on the amount of moisture available. These trees are often seen growing with multiple trunks, but can be pruned when younger to have only one. The branches of these trees are clothed with compound leaves 3 to 6 inches in length and equipped with 1/2- to 2-inch spines. In the spring and summer, 2- to 4-inch, fragrant, yellow flowers are produced that are very attractive to bees. Mesquite honey is ordinarily sold wherever these trees grow. Bean-like pods that follow the flowers are 2 to 6 inches in length and are used as feed for livestock. They were also used as food by the Native Americans. The wood of this tree is used for firewood and fenceposts and to smoke and charbroil food.

Pot Cultivation

Mesquites grow in hot, arid climates. They will flourish in deep, well-drained soil, in full sun. It can live in alkaline and dry soil. Pruning should be done in the winter.

Propagation

Seeds may be sown after soaking for 24 hours in tepid water. Hardwood cuttings may be used or suckers may be detached and planted.
