Planting and Care Tips for These Best Shrubs for the Desert Southwest

These three exceptional heat-loving shrubs are all relatively low-maintenance, but there are still a few things to keep in mind when planting and caring for them in your desert southwest landscape:


How to Plant Your Shrub:

  • Sun exposure: Choose a location that receives full sun exposure, at least 6-8 hours a day. Most desert plants thrive on sunlight and won't flower as well in shady areas.

  • Soil preparation: Amend your planting hole with well-draining soil. Desert soil can be heavy in clay or caliche, so adding sand, gravel, or compost can improve drainage and prevent root rot.

  • Digging the hole: Dig a hole that is at least two times wider than the root ball of your shrub. This allows the roots to spread out properly and establish themselves.

  • Planting depth: Plant your shrub at the same depth it was growing in the container (see the Tecoma 'Red Hot' container in the image to the right). Avoid burying the root crown, which is the area where the stem meets the roots.

  • Watering after planting: Water your newly planted shrub deeply and thoroughly to soak the root ball.


Watering Shrubs in the Desert Southwest:


  • Frequency: During the first year after planting, water your shrubs deeply and infrequently, allowing the soil to dry out completely between waterings. This encourages the roots to grow deep and search for water.

  • Established shrubs: Once established, these desert southwest shrubs are drought-tolerant and require minimal supplemental watering. However, they will benefit from occasional deep watering during the hottest and driest parts of the summer, especially if they are not receiving any monsoon rain.

  • Signs of thirst: Watch for signs that your shrub needs water, such as wilting leaves or dry, crispy foliage. When this occurs, give the shrub a deep watering to soak the root zone. For helpful watering tips, utilize regional watering guides.


prune shrubs regularly best shrubs for the desert southwest

Pruning Desert Shrubs:


  • Purpose: Light pruning can be done after flowering to maintain the desired shape and size of your shrubs. Pruning can also encourage bushier growth. Do not prune shrubs into unnatural shapes such as small balls and cubes in the Desert Southwest. Heavily shaved shrubs are more likely to fail in extreme heat or frost conditions.

  • Timing: Avoid pruning in the late summer or fall, as this can stimulate new growth that is susceptible to frost damage. The best time to prune these shrubs is in late winter or early spring before new growth begins.

  • Technique: When pruning, use sharp bypass pruners or lopping shears. Make clean cuts just above a bud or outward-facing branch. Avoid making stubs or shearing the entire plant, as this can encourage leggy growth.


Fertilizing:


  • Importance: Desert southwest soils are often nutrient-deficient. While these shrubs are low-maintenance, a light application of fertilizer can help them thrive and produce more flowers.

  • Frequency: Fertilize your shrubs lightly once a year in early spring. Use a balanced fertilizer formulated for desert plants, following the application instructions on the label. Avoid overfertilizing, as this can damage the roots and encourage excessive foliage growth at the expense of flowers.

Additional Desert Shrub Tips:


  • Mulch: Apply a layer of organic mulch or gravel around the base of your shrubs to help retain moisture, suppress weeds, and regulate soil temperature. Aim for a 2–3-inch layer of mulch, keeping it a few inches away from the stem of the shrub to prevent rot.

  • Monitor for pests and diseases: While these shrubs are generally pest and disease-resistant, be on the lookout for common problems like aphids, scales, and fungal diseases. If you notice any issues, treat them promptly with an organic pesticide or fungicide according to the label instructions.
