The variegated weigela is a deciduous shrub native to parts of Asia. The shrub is hardy to plant in USDA growing zones 5 through 8. It produces pink, trumpet-shaped flowers in late spring. Variegated weigela is propagated to produce additional plants by taking either softwood stem cuttings in late spring or hardwood stem cuttings once the plant is dormant in late fall. Softwood cuttings have the benefit of producing roots faster than hardwood cuttings.
Disinfect a sharp gardening knife in a solution of one part bleach and nine parts water. Rinse the knife well and let it dry before using on plants.
Take a 6 to 8 inch long softwood or hardwood stem cutting from current-year growth on the variegated weigela plant. Softwood cuttings are tender and snap when bent. Hardwood cuttings are mature stems in the dormant stage.
Prepare a rooting medium by mixing even quantities of sterile peat moss, course sand and perlite. Apply water to moisten the mixture and fill a rooting tray with it.
Remove all leaves from the bottom half of the softwood cutting. Hardwood cuttings will not have leaves. Dip the lower end of the cutting in rooting hormone and gently tap to remove excess.
Stick the variegated weigela in the rooting tray to a depth of 3 inches. Firm the medium around the cutting to hold it in place. Space the weigela cuttings so the leaves are not touching.
Mist the variegated weigela cuttings and planting medium with water. Cover the tray with a clear plastic bag to create a greenhouse environment. Open the plastic covering 2 to 3 times a day to mist the cuttings and refresh the air. Monitor the moisture inside the tray to make sure it does not get too wet.
Gently pull on the softwood variegated weigela stems after three weeks of growth and hardwood stems after eight weeks of growth to see if there is resistance from root growth. Grow the cuttings in a misted environment until the roots are at least 1 inch long.
Transplant the variegated weigela cuttings into individual growing containers filled with high-quality potting soil. Grow the cuttings indoors for the first year. Fertilize the variegated weigela cuttings after transplanting with a water-soluble fertilizer mixed at half strength.
