Description

Mesquite is a drought-tolerant, thorny, flowering tree native to northern Peru in the bean family. Plants in this genus are nitrogen fixers that often thrive in arid soil and are drought-resistant. Mesquite is often found in the wild on dry coastlines and arid, saline soils. Their fruits are pods that can contain large amounts of sugar and are a balanced staple carbohydrate. At maturity, a Mesquite tree can reach 39 feet in height with a nearly equal spread.

Mesquite tolerates sandy, loamy, or clay soil as long as it is well-drained. It prefers acidic soils and can grow in saline soils. It is best sited in full sun or partial shade and tolerates strong winds and drought, but not maritime exposure.

The tree produces a great deal of seed and it has escaped from cultivation in many areas, becoming invasive and forming dense thickets. It is a federally listed noxious weed in the United States and is not recommended for gardens.This tree can overshadow other vegetation, and its deep root system can tap into ground water and desiccate an area by using all available water. 

Diseases, Insect Pests, and Other Plant Problems:

No known diseases or insect pests.
