At its best:
Choose sideshoots as cuttings, pulling these away from the main stem with a thin strip of bark, or heel, still attached.
This heel is important as it is where the roots of the new plant will develop. Trim off the small flap of excess bark with a knife.
Remove the lower pairs of leaves so that the cutting has a length of bare stem that can be cleanly inserted into the compost.
If you're new to plant propagation, taking lavender cuttings in summer is a good way to start.
Dip the cut end of each cutting into rooting hormone. Insert several cuttings around the edge of small pots of gritty compost.
Water the compost well then cover the whole pot with a clear polythene bag to maintain a humid atmosphere around the cuttings.
Put the pots in a warm, shaded place. Once rooting has started (usually after four to six weeks), cut the corner of the bag to increase ventilation. Remove the bag completely after a few weeks. Leave cuttings in place until they are well rooted, then pot up individually.
