How to take dahlia cuttings

Posted in All Gardening Advice, Bulbs, May, June, Dahlias, on

Both the pinched-out tips and the shoots from the main tuber can be used as cuttings to make more plants. Simply plant up a couple of tubers in a shallow tray and wait for them to shoot. Once they have grown to about 4-5cm, they are ready to be used for cuttings.

Taking your cuttings

  • Either with a sharp knife, or squeezed between your thumb and forefinger, remove the main shoots, including a little bit of tuber.
  • Remove all but the top pair of leaves
  • Insert them into a gritty mix of compost, placing them at the edge of a opot, spaced so that they are not touching - about 3 per 3 litre pot.
  • Water and place in a warm spot, or cover the whole thing with a plastic bag supported on short canes around the edge of the pot and secured with a rubber band.
  • Put the pot in a propagator on capillary matting (to reduce the need for watering) and leave for 3-4 weeks. By that time, they should have rooted and will then need potting up individually.
  • When the frosts are over, these can be planted out in the garden and, by midsummer, you'll hardly know mother from daughter.
