Water moderately, waiting for the substrate to dry; greatly reduce watering in winter.

Fertilize with compost in autumn and with mineral fertilizer every 30 days in summer.

Prune intensively in autumn to strengthen the plant and control its lateral expansion.

They are shrubs resistant to the usual pests and diseases.

They are propagated by cuttings in summer, by division in fall and from seed sown in spring.
