Mulch well in spring and water thoroughly during dry periods for the first two or three years. Propagation of cultivars is always from cuttings or by grafting. Prune after flowering to keep plants compact using secateurs to thin and shorten branches, or hedge clippers to promote dense growth. Those with upright habits may be kept slender by training to a single leader and after flowering shortening and thinning lateral branches. Young plants require thorough watering during dry periods over the first two or three years. Mulching helps to conserve moisture and suppress weeds. Plants in very acidic soil will benefit from a light application (50g/m2) of dolomite lime every three years.
