The rose of sharon is an exquisite plant that can be easily transplanted as long as you follow the appropriate steps. It is easy to grow in hardiness zones 4 through 9, so if you live in one of those regions and have to transplant your tree, you shouldn't have too much trouble. However, make sure you know exactly how best to do so in order to maintain the rose of sharon's good health.
Before you do anything to remove your rose of sharon, you should first clear away the area directly surrounding it. Rake leaves, remove mulch and twigs, and throw them away or store them elsewhere, like in your garage, for the time being. You may also have to trim away a few of the branches closer to the base of your tree for its own protection.
Next, gently dig up the tree. Be especially careful while working on freeing its root ball, as any accidental damage to this area can cause the rose of sharon to go into shock. Gently remove the soil from the area until the tree's roots are freed from the ground. Pull the tree up and move it to its new spot. Make sure that the hole you dig is twice as wide as the root ball, which is exactly the same activity you performed when you originally planted your rose of sharon.
Move the soil gently over the root ball, but keep it slightly over the ground. Apply a good layer of thick mulch around the base of the tree and water the area sufficiently so that the roots can more easily grasp the earth around it. Make sure to continue to water your tree regularly over the next month. If all goes successfully, you should begin to notice more growth after that time. You will then be able to stop watering the roots, as they will have reestablished themselves in the soil.
