The new plants must be grown in pots for at least two years before being planted, allowing them to grow and develop a root system strong enough to be transplanted without being subjected to stress that could compromise the rooting. In autumn, cuttings can also be made, using the young branches and then burying them in pots to obtain new shoots.
