Whether you have new rose of sharon plants from starting seeds or growing cuttings, there will come a time when you need to transplant the young plants to their permanent location. Whether it is spring, fall, or the middle of summer, it's easy to transplant a rose of sharon and enjoy bright, colorful blooms as soon as the following year. With a plant like rose of sharon, which can live for decades, the hardest thing about transplanting it may be finding an appropriate planting site.
Select a site for your rose of sharon that is in full sun with well-draining soil, neither swampy nor dry. Loosen the soil and create a hole as deep as the pot your plant is in and three times as wide.
Add garden soil or compost to the removed soil if you find it to be sandy. Your rose of sharon needs a moist soil that doesn’t drain immediately, so adding looser, more absorbent soil can help improve the success of your transplant.
Take the plant out of the pot and untangle larger roots around the base of the plant with your fingers. Spread out the roots from the bottom and set the plant into the empty hole.
Fill in the hole with your broken-up soil. Work the soil around to all sides of the plant and press it to firm up the soil and stabilize the plant so it cannot move if a rough wind blows.
Water the plant and disturbed soil to moisten it thoroughly without soaking it. Keep the soil well-watered for the first month.
Spread 2 to 4 inches of mulch around the plant to prevent weeds and maintain the moisture in the soil.
