How to Plant a Joshua Tree

Joshua trees (Yucca brevifolia) are iconic plants of the Mojave Desert in the southwestern United States. If you live in a desert climate or have a dry, sunny garden, you may want to add a Joshua tree to your landscape. Follow these steps to successfully plant and care for a Joshua tree.

Choose a Site

Joshua trees thrive in full sun and well-drained soil. The soil should be slightly acidic to neutral, with a pH of 6.1 to 7.8. Look for a site with plenty of space for mature trees, as they can grow up to 50 feet tall and 20 feet wide. Avoid planting near buildings or other structures that could be damaged by the tree's roots or branches.

Prepare the Soil

If your soil is alkaline, you may need to add sulfur to lower the pH. Mix sulfur into the soil at a rate of 1 pound per 100 square feet. If your soil is heavy or poorly drained, add sand or gravel to improve drainage. Dig a hole that is slightly wider than the root ball of your Joshua tree, and break up any clumps of soil to help the roots spread out.

Plant the Tree

Lower the Joshua tree into the hole, making sure the top of the root ball is level with the soil surface. Fill in the hole with soil and tamp down gently to remove air pockets. Water thoroughly, and add a layer of mulch around the base of the tree to help retain moisture and suppress weeds.

Water and Fertilize

Joshua trees require very little water once established, but they should be watered deeply and infrequently during the first year after planting. Water once a week during the first month, then reduce to once a month for the rest of the year. Once the tree is established, it can survive on natural rainfall alone. Do not fertilize Joshua trees, as they require low-nutrient soil to grow properly.

Prune and Maintain

Joshua trees generally require very little maintenance, but you may want to prune dead or damaged branches during the tree's dormant season in late fall or early winter. Avoid pruning healthy branches, as the tree's unique shape should be preserved. Also, be sure to check for any pests or diseases that may affect the tree's health.

Conclusion

Planting and caring for a Joshua tree requires some preparation and attention to detail, but the rewards are worth it. With proper care, your Joshua tree can thrive and bring the unique beauty of the Mojave Desert to your landscape.
