Weigela blooms from early spring to the middle of summer with colourful blooms that attract hummingbirds and butterflies. Weigela is a native of Asia and grows well in U.S. Hardiness zones 4 to 8. You can propagate the beautiful foliage of this plant from stem cuttings taken before flowering or after the blooms are done for the season.

Cut 6- to 8-inch stem sections of the weigela while the plant is still dormant in the early spring or after blooming in the late summer. Remove the bottom leaves of the stem cuttings to expose 3 to 4 inches of the cutting. Set the cuttings in water until you are ready to plant.

Fill a growing tray or pot with quality potting soil and water the soil thoroughly. Mix the water into the soil so there are no dry spots in the middle of the pot. Stick your forefinger into the soil to create holes for the weigela cuttings.

Pour 1 to 2 tbsp of rooting hormone onto a paper plate and dip the cuttings into the powder, coating the bare stem well. Shake off any excess powder and stick the stem cuttings 3 to 4 inches into the growing tray. Secure the cuttings in the tray by tamping down the soil around the stems.

Cover the growing tray with clear cling film or place the entire pot into a clear plastic bag. Seal the plastic around the growing tray to create a miniature greenhouse for the cuttings. Place the tray into a bright location but out of direct sunlight.

Monitor the weigela stem cuttings during the propagation period by removing dead or dying cuttings and maintaining the greenhouse effect. Remove the plastic for an hour each day to allow air to circulate among the cuttings.

Check for root development after four to six weeks. The developing root system will show resistance when giving the stem cuttings a gentle tug. Remove the plastic and continue growing until the root system is fully developed. Transplant the new weigela plants into separate containers and grow the plants to the desired size before planting in the garden.


Direct sunlight on a stem cutting causes the cutting to burn and die.
