Clematis can be propagated by taking cuttings or layering

Cuttings

Select a stem: In April or May, choose a healthy, flexible stem from the current season’s growth. 

    Cut the stem: Using sharp secateurs, cut the stem above a leaf joint, about 7 cm long. Avoid cutting the very tip of the stem. 

    Remove leaves: Remove some leaves from the cutting to reduce moisture loss. 

    Prepare the pot: Fill a pot with a mix of compost and grit. 

    Dip in rooting powder: Dip the base of the cutting in rooting powder and shake off excess. 

    Plant the cutting: Push the cutting into the pot so the leaf joint is level with the surface. 

    Cover the pot: Cover the pot with a clear plastic bag or place it in a propagator. 

    Water and place in a warm spot: Water the pot well and place it in a warm spot out of direct sunlight.

     Check the cuttings: Check the cuttings every few days. 

    Pot up the cuttings: Once the cuttings have rooted, pot them up separately. 

    Plant in the ground: After about a year, the cuttings should be established enough to plant in the ground. 

    Layering 

    Select stems: In spring, identify flexible stems and lower them into the soil.

    Make a cut: Use a sharp knife to make a small cut into the stem where it will touch the soil.

    Sprout roots: The stem should sprout roots directly from the cut.
