How do you propagate Plectranthus?
Most propagation is done from cuttings during the early part of summer and spring. Although the cuttings will root at any time of the year, they have a long summer ahead to establish if they are propagated at this time. Cuttings may take the form of soft-wood, semi-hardwood, but tip cuttings are usually the best. Softwood cuttings are taken from spring to early summer (Apr-Jun), using material from the soft and flexible young shoot tips from this seasons growth, which root readily. Use for hardy and tender perennials, deciduous shrubs, climbers and some trees.
