How to take cuttings of catmint
1 Choose a length of this year’s healthy, ideally non-flowering, growth and cut 4in (10cm) away.
2 Strip away the lower sets of leaves and pinch out any flower buds as they will divert energy from root growth.
3 Dip the cut ends in hormone rooting powder or gel to promote good root development.
4 Insert the cuttings around the edge of a clay pot filled with dampened seed and cutting compost.
5 Seal the cuttings in a clear plastic bag, making sure it isn’t touching any plant material.
