Propagating Viburnum carlesii
Softwood cuttings will give you the best success rate when trying to propagate Viburnum carlesii and cuttings are taken in spring from the new growth. Cuttings will root quickly and be ready for potting on into larger pots in mid-summer, if not over-winter until the following season.
Take a cutting from the newest fresh growth around 4 inch (10cm) long, remove the lower leaves and take a fresh cut just below the node (where the leaves are). This is where the new roots should shoot, pinch the top out and dip in rooting powder to help promote root growth. Make a hole in the compost which should be 50% seed compost and 50% grit sand and insert the cutting. Tap the sides to settle the compost and water well. Ideally you want to place in a propagator with bottom heat. Softwood cuttings root quickly so it should not be too long before they are ready to pot on.
