Popular Desert Trees and Care Guide

Have you ever thought of planting a desert tree in your garden, or does it sound too wild to you? It's not! Read on to learn about the popular desert trees and get started with your own arid oasis.

Deserts might often be associated with barren landscapes and scorching temperatures, but did you know that there are a variety of trees that can survive and even thrive in these conditions?

These trees are preferred by gardeners and homeowners for their resilience and drought tolerance and can be a great addition to your garden. If you are intrigued by the idea, check out our list of the most popular desert trees, complete with a care guide!

What Kind of Trees Can Grow in a Desert?

A Desert is not usually thought of as a hospitable environment for trees, but several tree species can thrive in these conditions. Before we move on to listing the various trees, let's understand what kind of trees can survive the desert.

  • Trees that are tolerant of both low and high temperatures. This is essential because the temperature in a desert can get very high during the day, and extremely cold during the night.
  • The trees that withstand long periods of drought. This is another essential requirement because water is scarce in a desert.
  • Trees that thrive in full sun as there's not much shade in a desert.
  • Trees capable of growing in rocky, sandy, or infertile soil as the soil in a desert is not very nutrient-rich.
  • Trees with shallow roots. This enables the tree to get as much water as possible from the little moisture available.

It seems hard, but you can find several trees in the desert with lush foliage and bright flowers. To understand desert trees better, let's look at their characteristics.

Characteristics of Desert Trees

Deserts are among the harshest environments on Earth. They are hot and dry with very little water available. The soil is often infertile, rocky, and sandy. Despite all these challenges, there are some trees that have adapted to these conditions and can survive and even thrive in a desert - here's how.

Small or No Leaves: To prevent moisture loss, many desert trees have small leaves or no leaves at all. The leaves are often leathery, which reduces evaporation.

Thorns: Desert plants often grow slowly, and on low nutrients, so most of them have thorns to protect themselves from herbivores.

Long Shallow Roots: The roots of some desert trees can be as long as the tree is tall, which helps them find water deep underground. Plus, the roots are shallow and can absorb moisture quickly.

Water Storage: Some desert trees have the ability to store water in their trunks, leaves, or roots to help them survive long periods of drought.

Thick Waxy Stems: The stems of desert trees are thick and green, which helps in photosynthesis. Plus, they are covered with a waxy substance which assists in retaining water.

Popular Desert Trees

Now that we know what kind of trees can survive in a desert and what their characteristics are, let's look at some of the most popular desert trees.

Choose a location: Select an area of your yard that receives full sun. Desert trees need lots of sunlight to thrive.

Prepare the planting hole: The planting hole should be twice as wide as the tree's root ball.

Set the tree in the hole: Gently set the tree in the hole, ensuring that the roots are spread out evenly.

Fill in the hole: Backfill the hole with soil, tamping it down gently as you go.

Water the tree: Water the tree deeply, making sure to wet the entire root ball.

Planting Tips

Here are a few valuable tips to keep in mind when planting desert trees:

  • It's best to plant desert trees in the spring or fall.
  • Desert trees must be watered deeply and regularly during the first growing season.
  • Make sure the tree is not planted over a sewer line or underground utility because the roots grow deeper and can damage them.
  • Mulch around the tree's base to help conserve moisture.
  • If the specimen shows any signs of disease, pests, or damage, do not plant it.
  • Make sure it is planted upright.' Properly replant if necessary, but do not over-support them.
  • Native species won't need soil amendments, but if you are planting a non-native species, you may need to amend the soil with organic matter.

Caring for Your Desert Tree

Once your desert tree is planted, it's important to care for it properly to ensure it thrives. This care guide will help you keep your desert tree healthy and happy:

Soil Requirement

Desert trees are up to some level adaptive and can put up with different soil types but prefer well-drained, sandy, or gravelly soils. If your soil is heavy or clay-like, you may need to amend it with organic matter before planting. Plus, be sure to check the drainage in your yard before planting. If the drainage is poor, you may need to take steps to improve it before planting your desert tree.

Sunlight Requirement

Desert trees need full sun to thrive. Be sure to choose a location in your yard that receives at least six to eight hours of direct sunlight daily. However, some species of desert trees can tolerate partial shade. So if you're not sure which tree to choose, ask your local nursery or garden center for help.

Watering Needs

Desert trees need to be watered deeply and regularly during the first year. After that, they will need to be watered less frequently. The best way to know how often to water your desert tree is to check the soil before watering. If the soil is dry to the touch, it's time to water. However, once the tree is established, it will be more drought tolerant and need less water.

Fertilizing Needs

Desert trees do not need to be fertilized. In fact, over-fertilizing can be harmful to the tree. If you decide to fertilize your desert tree, do so sparingly and only use a fertilizer specifically designed for desert trees.

Pruning Needs

Essentially, desert trees do not require pruning, and you should only prune them if necessary. If you need to remove dead or damaged branches, do so carefully. And if you need to shape the tree, prune it in the late winter or early spring.

Pest and Disease Control

Desert trees are susceptible to a variety of pests and diseases. Some of the most common include aphids, caterpillars, scale insects, and spider mites. To control pests and diseases, it's essential to choose a healthy tree from the start. However, you should still inspect it regularly for any signs of trouble.

And if you encounter pests or diseases on your desert tree, there are several organic and chemical controls that you can use. However, it's always best to consult a professional before using any pesticide.
