More Information
Botanical PronunciationPROS-oh-pis chil-EN-sis vel-oo-TEE-nuh)
LoreThe genus Prosopis includes the famous native trees of the American Southwest that produce nutritious pods vital to the material culture of many Native American tribes within its range, used for both food fiber and implements. The Pima Indians of southern Arizona referred to the mesquite as the Tree of Life. The Chilean mesquite has been widely planted in the Southwest and readily cross pollinates with the native species. Spontaneous hybrids have appeared naturally which display qualities of both ancestors. Like many members of the legume family, mesquites have the ability to restore nitrogen to the soil.

Thrives in lean to average, fast-draining soils. Water deeply, regularly during the first growing season to establish an extensive root system. Once established, water only occasionally, as needed to encourage vigor; over-watering causes structurally weak wood. Fertilize lightly when new growth begins in spring.
