Planting and Care Tips for Desert Shrubs

The successful performance of desert shrubs depends on proper planting and early care:

• Full Sun: Locate shrubs where they receive at least six hours of direct sun daily.

• Soil Preparation: Ensure soil is well-drained. In heavy clay or caliche soils, incorporate coarse sand or gravel to improve drainage before planting.

• Planting Depth: Plant so the root crown sits at or slightly above finished grade to promote healthy root growth.

• Mulch: Use a light layer of organic mulch to conserve moisture, keeping it a few inches away from the shrub stems.

• Watering: Water deeply after planting to settle the soil. Once established, reduce frequency to encourage drought tolerance.

These practices help shrubs transition from nursery stock to resilient landscape performers.
