Mesquite

Prosopis

A genus of trees that are closely related to the Acacias. The seed pods are a food source that can be ground to flour. The pods can also be used to feed livestock. The flowers are used in the production of honey. The timber is aromatic and the smoke is used to BBQ meats.
They prefer full sun on deep well drained soil. Most Mesquite are extremely drought tolerant. Mesquites are very deep rooted and hate root disturbance. The wide spreading Mesquite roots have also been found as deep as 200 feet in their search of water. It is important to either plant from seed on permanent site or transplant while very small. Mesquite is very easy to grow in hot dry climates and have multi-use potential in many climates for reforestation as well as food and timber.
The massive network of roots on these trees can be used to prevent erosion, especially on stream banks. The roots of the Mesquite can also fix nitrogen thus improving the soil. Also never throw away old Mesquite pods, they can be used as a nitrogen rich fertilizer.
Young trees should be trained to a single trunk, thin out overcrowded thicket-like branches.
Propagation from seed is easily done if soaked in boiling water for 15 minutes then left in cooler water for 12 hours before sowing. It is also possible to speed up germination by nicking the seedcoat or scarifying it with acid before soaking it in water. The seed will not germinate until water penetrates through the hard seedcoat. In the wild, the seeds will often soften as they travel through the digestive systems of animals especially cows that eat the pods, explaining the increase of Mesquite in much of the southwestern U.S. Propagation can also be done from half hardened cuttings.
Pharmacology: Most species contain Tryptamine. Prosopis juliflora contains
5-HTP.

MESQUITE HAS MASSIVE POTENTIAL AS A FOOD CROP FOR DRY CLIMATES!!! ILL BE POSTING MY OWN VIDEO ON TOPIC SOON.

Prosopis affinis ( Algarobilla )
An attractive, massive trunked, broad-spreading, medium-size tree, reaching up to 65 feet, that is native to South America in southern Bolivia, Paraguay, southwest Brazil, Uruguay and northwest Argentina. It is threatened by habitat loss in the wild. A well grown tree resembles the Honey Locust in appearance. Some records include: 2 years - 7 x 10 feet; 4 years - 9.5 feet; 5 years - 11 feet; 6 years - 13 feet; 9 years - 16 feet.
The leaves are deciduous but persist very late in autumn or often until mid winter.
It is found in the wild on both upland sites and flood plains usually in open woodlands. Hardy zones 9 to 10, it thrives best where average annual rainfall is 24 to 48 inches per year, though it will tolerate the occasional drought. It is native to moisture climates than the other South American Mesquites.

Prosopis africana

Prosopis cinerea
A fast growing, medium size tree native to the driest parts of Arabia, Iran, Afghanistan, Pakistan and India. It can Spread vigorously by root suckers. Root suckers have spread as much as 50 feet from original tree.
Hardy north to zone 8b ( tolerating 16 F with no damage ), it tolerates as little as 4 inches of rainfall per year. It thrives in parts of the U.S. southwest including Tucson, Arizona.

Prosopis flexuosa
A spiny, small tree, reaching a maximum size of 40 feet, that is native to Chile, Argentina and dry valleys of the Bolivian Andes. It is considered a weed in parts of Argentina where it forms thickets on land used for livestock grazing. However a well grown tree also contributes valuable timber.
The lacy pinnate leaves are composed of linear leaflets. The foliage is mid-green.
The pods are up to 11.5 x 0.4 inches.
Hardy zones 8b to 10 ( tolerating 10 F ).

Prosopis glandulosa ( Honey Mesquite )
A spiny, crooked branched medium size tree native to the western and central U.S. from southern California to southwest Utah to central Nebraska; south into Mexico. Some records include: 4 years - 20 feet; 20 years - 30 x 40 feet; largest on record - 70 x 90 feet with a trunk diameter of 5 feet; longest lived - 250 years.
An excellent shade tree in dry climates, especially in the central and western U.S. if trained and limbed up at a young age. It has invasive potential in Chile & Argentina ( use native South American Mesquites there ), South Africa and Australia and its use should be avoided there. Honey Mesquite is very deeply rooted, up to 60 feet in depth.
The bipinnate leaves are divided in to 2 or rarely 4 pinnae, up to 10 inches in length, are composed of up to 34 narrow elliptical leaflets, up to 1 x 0.25 inches.
The fragrant, fluffy, white to orange-yellow flowers are borne in slender spikes, up to 6 inches in length, during spring.
The nectar rich flowers attract honey bees.
They are followed by narrow, linear pods, up to 9 x 1 inches, that constrict between the seeds. The pods ripen during summer and can be harvested from mid summer to as late as September. They are sometimes produced so abundantly that they cover the ground beneath mature Mesquite trees. The pods are best immediately after they naturally fall off the tree and the quality varies from tree to tree. The pods are similar in flavor to that of a distant relative - the Carob tree ( Ceratonia siliqua ).
Mesquite pods can also be gathered before they ripened and be eaten raw or cooked as a vegetable. The entire pods ( incl. the seeds ) can also be dried and ground to a meal to make excellent flour. By throwing some pods on a barbecue you can add great flavor to cooked meats. Mesquite bread is very good and the flour can also be mixed with wheat flour to make other recipes including muffins. After grounding he pods to a meal, when you sift out the fibrous parts, do not throw them away. If you soak them in water to leach out the sugars - you can make a very good drink. Simply by boiling the pods for 20 minutes, you can make a good drink. Another drink can be made by mixing Mesquite flour with water.
Syrup every bit as good as Maple syrup can be made from boiling the pods.
The stems are armed with spines up to 2 inches in length. The bark is rich brown.
Old trees have very coarse bark with ragged ridges.
Mesquite wood is very hard but trees are often of too poor of form to make them commercially viable for lumber though they can be used for log cabin homes and rot resistant fence posts. Mesquite trees can be coppiced for fenceposts, poles and firewood which burns very hot.
Hardy zones 5 to 11. This tree is drought tolerant due to its deep roots.
It is also very heat tolerant as well as alkaline soil tolerant but shrubby on shallow soil. Mature Mesquite should be irrigated during extended severe drought only.
Honey Mesquite is not known to grow in the humid eastern U.S.
