Propagation
Take hardwood cuttings during winter.
Apical grafting during spring and shield budding during summer.
Take greenwood cuttings during early summer and apply bottom heat.
Culture
Avoid pruning during winter or early spring as the oozing sap may encourage fungal disease and the flowers appear on one year or growth. Prune after flowering period and thin at the centre of the tree for air penetration.
On grafted trees, remove any growth below the graft union. When used as a cut flower cut back stem to the nearest node on the stem.
