Trees that are native to the Southwest are fairly resilient to drought conditions. However, even native desert trees can benefit from supplemental watering during certain times. And if you happen to have non-native trees on your property that cannot handle drought conditions, you can expect to water these much more frequently than the native species. If you’re unsure of when to water or how much water to provide, you can always consult a landscaping company for guidance.
Checking the Soil
You could use a moisture meter to check the dampness of the soil around your trees. If you don’t have one, all you need is a screwdriver. Insert it into the ground. It should pass easily through moist soil, but encounter resistance at dry soil. If it becomes difficult to press the screwdriver more than six inches into the soil, then you’ll need to water.
Using the Right Watering Technique
In this desert region, it’s important to conserve water as much as possible. That’s why it’s best to avoid overhead sprinklers, as these tend to waste water. Instead, opt for a soaker hose. Spiral the soaker hose around the base of the tree in loose, widely spaced coils. Allow it to run for as long as it takes to penetrate the soil at least six inches deep—usually at least an hour. It’s best to water during the early morning or evening hours to reduce evaporation.
Watering New Trees
A recently planted tree requires a great deal more water than an established tree, especially in the desert. For the first few months, the root ball should be kept moist. This may necessitate watering three or more times per week. After this initial period, you’ll need to water less often, yet still provide more water than you would for an established tree.
