1. Planting: Place in an area where it can receive full sunlight (between 6-8 hours per day) in dry soil. Since this tree grows rapidly and widely, space it from other plants and trees accordingly. For an instant privacy screen, plant these trees 5 feet apart. To give the trees a bit more room (which requires less work in terms of pruning), plant them 20 to 30 feet apart. You can plant them in a straight line, or in two staggered rows. 

When you're ready to plant, dig a hole as deep as the root ball but twice as wide. Then, place the tree in the hole to check the depth - if the level of the soil surrounding the hole is higher than the root ball, pick the tree up, put some more soil in the hole, and replace the tree. Then, back fill the soil and water to settle.

2. Watering: Water regularly until established. Since this tree thrives in hot, dry conditions, be careful not to overwater. 

3. Pruning: Desert Willows require pruning primarily to control their size and shape and to remove dead branches. Cut dead branches all the way back to the trunk, stopping at least ½ inch before the trunk. The pruning cut will heal itself.

If you’re growing the Willows as a hedge, trim once a year in the winter, which will encourage the tree to branch out and become denser throughout the summer.

4. Fertilizing: Fertilizing your Desert Willows isn't necessary and excessive fertilizing can damage them.
