3. Keep Pruning to a Minimum
Avoid pruning during the summer months, as it can place undue stress on the plant. Pruning may encourage plants to generate more foliage, while their roots could be experiencing water stress. Furthermore, excessive pruning can expose plant tissue, increasing the likelihood of sunburn.
4. Water Deeply, Wide and Infrequently
For desert plants to develop a strong root system, it is crucial to water deeply and thoroughly, allowing the soil to dry out between watering intervals. This is particularly important for desert trees and shrubs. Avoid keeping the soil consistently moist or shallow watering as these are not advised for optimal root growth.
5. Add Mulch
Mulch is a protective layer applied to the soil’s surface. Opt for an organic mulch, such as compost, to retain moisture effectively. It is particularly beneficial for “thirsty” plants like citrus, but you can also use it for desert trees, shrubs and other perennials. Apply a layer of about one to two inches around the plant, ensuring it does not touch the base of the plant stem or trunk. Additionally, mulch provides the extra advantage of keeping the soil cooler.
