Choose healthy stems and remove a 7cm-long section from each with a sharp knife. Choose non-flowering shoots or pinch off the flower buds.
Remove the lower leaves and sideshoots, then cut cleanly below the leaf joint. Cuttings should have one or two pairs of leaves.
Dip the cut ends in hormone powder to improve rooting. Tap off any excess powder.
Fill a terracotta pot with seed and cuttings compost. Insert the cuttings around the edge of the pot. Water and place in a warm propagator. Move each cutting into its own pot when fully rooted.
