Pomegranate is #1 in our TOP 10 Heat Resistant Plants!

The bountiful pomegranate tree is native to the Mediterranean region which has similar growing conditions as the Arizona Sonoran Desert.  Pomegranates thrive in the drier climates of California and Arizona.  As a matter of fact, in 2009 the first commercial pomegranate farm started in Arizona. This fruit tree seems satisfied with our alkaline soil and experiences no deficiencies!

Although the pomegranate originated in Iran, ancient records show it is one of the oldest known cultivated fruits.  Biblical Archaeologists discovered fruit such as the pomegranate,  was much more than a food; it had symbolic significance for the Ancient Israelites.  The antiquated Greeks believed pomegranate juice was the “symbol of love”.  The botanical name for pomegranate is Punica granatum belonging to the family Lythraceae. P. granatum has more than 500 cultivars.  In 1769, the pomegranate was introduced into California by Spanish Settlers.

In the sizzling, sunniest area of our yard we now have five pomegranate trees, shrubs ranging from six months to six years old.  “Wonderful” is our cultivar and is also the most common cultivar for Arizona.  Recently,  we had record temperatures of 113 degrees F; with higher temps forecasted for next week.  There was some vexing over the younger plants, but it proved to be unnecessary.  We are delighted to report our Punica granatum flourished in the extreme desert heat!

The adamant pomegranate is drought tolerant and does best with well-drained soil, semi-arid climates and plant hardiness zones 8 to 10.  The fruit is adversely affected in wetter climates along with the plant becoming prone to root decay.  Tolerant to frost down to 20 degrees F.  Easy to grow, this deciduous tree can mature to 30 feet; but it is more common to see pomegranates at 12 – 15 feet.

The leaves of Punica granatum are glossy, narrow, lance-shaped and deer resistant.  The lavish flowers are bright orange-red with a fleshy tubular calyx.  Some cultivars are grown for their flowers alone and used as ornamental trees.

HARVEST:

The fruit is ripe when it reaches its distinctive color and it makes a metallic sound when tapped.  Overripe fruit will begin to crack and the seeds will become harder.

EATING:

The easiest way to eat a p. granatum is to use a bowl of water to separate the seeds.  The seeds sink and the white membrane floats.

Native Arizona Mesquite Trees – growing tips – Velvet mesquite trees, The Tree of Life

Honey and Velvet Mesquite Trees can take the extreme heat and the cold! This tree grows fast.  What is the most common tree of the Desert Southwest?  It is the Mesquite! Like many members of the Legume Family, mesquite trees restore nitrogen to the soil.

Mesquite Tree Arizona
Honey Mesquite Tree

There are 3 common species of NATIVE mesquite trees:  Screwbean Mesquite (Prosopis pubescens ),  Honey Mesquite (Prosopis glandulosa), and Velvet Mesquite (Prosopis velutina).

Native Desert Tree – Honey Mesquite

These native trees are extremely drought tolerant. Honey Mesquites are more rounded with big, floppy, drooping branches.  The foliage is feathery and straight – paired with sharp spines on twigs.

This tree normally reaches 20–30 ft, but can reach as tall as 50 ft (15 m). The growth rate is medium.  Honey mesquite coppices  (it will make new growth from a root or stump if it is cut down), making permanent removal extremely hard.  If a single trunk is cut down the Honey Mesquite will replace it with a multiple trunk version.

The Honey Mesquite has pale, yellow, elongated spikes and bears straight, yellow seed bean pods. In this picture you can see how long and strong this mesquite’s spikes are. I’ve learned NOT to wear flip-flops when walking around our Honey Mesquite!

Caring for mesquite trees is a simple process after the tree has fully matured. Mesquite trees need a full day’s worth of direct sun light to grow. Make sure to plant your mesquite tree in a place where it will always have a lot of quality sun.

Good staking is crucial to the mesquite tree, especially in areas with severe summer storms, monsoon season, or high winds.

The shortcoming of a Chilean or Honey Mesquite tree is wind damage. Proper staking and proper watering can help you avoid wind damage with your mesquite trees.

Make your Mesquite trees “seek out” water and nutrients by careful arrangement of your irrigation emitters and scheduled DEEP irrigation. This will develop a more dispersed root system and reduces the risk of wind throw.

Pruning will keep your tree from becoming messy, while stimulating new growth on those branches that you pruned. The dead, diseased, broken or weak branches, drain the Mesquite tree’s energy.

Mesquite bean pods are rich in carbohydrates and have very low moisture content, making them an excellent source for harvesting, processing, and storage.  A variety of animals eat the seeds such as quail, dear, javelina, coyotes, squirrels and rats.

Historic records have indicated that almost every part of the mesquite tree has a use. The Pima Indians of southern Arizona referred to the mesquite as the TREE OF LIFE.

During the inevitable droughts and deprivations of desert frontier days, the mesquite trees served up the primary food source for caravans and settlers.  Mesquite beans became manna from heaven.

Medical studies of mesquite trees and other desert foods, said that despite its sweetness, mesquite flour (made by grinding whole pods) is extremely effective in controlling blood sugar levels in people with diabetes.

Mesquite trees have lateral roots that extend far beyond the canopies of the plants and tap-roots that penetrate well below the surface of the soil.  Some mesquites may live for more than two centuries;  according to U. S. Department of Agriculture, Forest Service.

(Prosopis Velutina) Velvet Mesquite is the most common of the North American varieties, it ranges from southern Arizona, southwestern New Mexico, and most common to the Chihuahua and Sonoran deserts of Mexico.

Native Desert Trees, Velvet Mesquite Tree

Velvet Mesquite Trees are a deciduous plant that benefits by being able to retain moisture during the winter or exceptionally dry seasons better because water does not escape through the leaves.  These Mesquite trees have elongated bean pods that are sweet to taste when ripe ( reddish-yellow color).   This native tree has thorns with varying lengths even on the same branch.

For the first year,  deeply water your mesquite tree every week or so until it has properly matured. Once your velvet mesquite tree has matured, it can survive with a little supplemental water in addition to natural rain. In case of droughts, do water your mesquite trees more often.

Velvet Mesquites hold the record for deepest root (160′); these tap-roots can tap into deep, underground water supplies that aren’t available to the average plant.

The seeds of mesquite trees need to be scarified (abraded in flash flood or digestive tract) to germinate. Coyotes, and other desert animals eat the bean pods regularly.

The Thornless Chilean Mesquite is the best tree for Shade

The Shade from this Thornless Chilean MesquiteProsopis chilensis, creates a 10-15 degree cooler temperature in our yard. The dogs use the shade from the Mesquites to stay cool.

Below in the photo is a Hybrid Mesquite that is Thornless, called the Chilean Mesquite. By providing abundant shade, a lush green leaf canopy and graceful fissured brown trunks, Thornless Mesquites are another of the wonderful trees that dispelled the myth that desert landscapes were hot, barren, spiny and uninviting. Chilean or Thornless Mesquite trees are beautiful and one of the best shade trees for your yard.

Our Chilean Mesquite Tree makes the best shade tree

The Thornless (Chilean) Mesquite Tree pictured here is approximately 15 years old.

Shade is a welcome addition to all desert landscapes, xeriscaping, especially in the extreme heat of The Sonoran Desert.  The shade produced by Thornless Hybrid Mesquites, (Chileans) can range from filtered to quite dense which can inhibit the growth and flowering of some under-story plantings.

When deciding where to grow your Mesquite Tree, consider the ultimate shade that can be produced by these trees and how it will affect the growth and flowering of under-story plants. Also note from my experience that any plant, vine, or flower placed too close to the Mesquite will not do well.

At maturity, Chilean Mesquites can be up to 30 feet tall and as wide…with dome-shaped, spreading canopies, this Hybrid in the photo below is much taller.  They are cold resistant to 10 to 15 degrees F.  Thornless Mesquites are semi-deciduous, losing  a portion of their leaves in warmer winters in the Phoenix, Arizona and Palm Desert, California areas.

Las Vegas and Tucson, Arizona will have a little more leaf shed due to the lower winter temperatures. Leaves remaining through the winter are shed rapidly in spring just prior to bud break. Mesquite trees are often easily damaged or completely uprooted by the high winds associated with the summer rainy season.  Proper tree staking is essential!!

Below is a picture of our 15 year old Chilean Mesquite Tree, majestic, healthy and strong. This Tree is one of,  if not the tallest Mesquite Tree, or any tree in our area.
