Follow these easy steps to plant your Arapaho Crape Myrtle tree
Crape Myrtle trees like full to partial sun and moist, slightly acidic soil. So keep this in mind when choosing the planting site for your Arapaho Crape Myrtle tree. Dig a hole slightly shallower and about twice the diameter of the root system. Use your shovel or other garden tool to scrape the soil on the walls of the planting hole so the roots can easily penetrate as they grow.
Set your Arapaho Crape Myrtle in the planting hole and spread out the roots. The top of the root ball should be about an inch above the surrounding soil. If there is a preferred side to your tree, now is the time to turn it so you can see it. Then make sure the tree is straight up and down in the hole. A level is very helpful for accuracy.
Apply water as you backfill the hole with soil to remove any air pockets. After the transplant is complete, water the tree again well. To keep the soil moist, it is recommended that you mulch around the tree. Mulch also helps make the soil more acidic. Use enough mulch to reach a depth of 2"-3" but keep a small circle around the tree trunk that is not covered with mulch.
