How to take dahlia 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.
