When to take Root Cuttings:
Root cuttings are best taken in late winter, when the plant is dormant.
How to take Root Cuttings:
Lift the plant that you want to propagate and wash its roots. Select some healthy looking roots of pencil thickness and cut them off close to the crown with a sharp knife. Trim off thin side roots and cut each root into lengths of about 2 to 4 in (5 to 10 cm). Make a straight cut at the top and a angled cut at the bottom, which will be a guide as to know which way around to put the cutting into the compost. Fill a pot with cutting compost and make some holes with a dibber or pencil. Moisten the compost. Insert the cuttings vertically into the holes leaving the top end of the cutting flush with the compost surface. Roots that are very thin should be put horizontally onto the surface of the compost and covered with more compost. Cover the pots with some sand or grit and place them into a propagator or cold frame. The cuttings don’t need watering until they have started to root. As soon as the young shoots have appeared it will be time to pot the new plants up into there own pots. They can stay in their pots until they are established enough for planting out into the garden.
