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, all the way round the edge of a pot, spaced so that they are not touching – about 3 per 3 litre pot.

Water and place in a warm place, or cover the whole thing with a plastic bag supported on short canes round 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. They should then have rooted and will then need potting up individually.

When the frosts are over, these can also be planted out in the garden and, by mid-summer, you’ll hardly know mother from daughter.
