It can be seeded or transplanted.

Place seeds in soak in a bowl with hot water, around 40°C, leave them for about 24 hours until they begin the process of germinating.  Drain them, then leave them to dry, then plant them.  Germination takes about 4 weeks. Water normally.

Harvest by picking off external stems above soil level so as to stimulate further growth.  Picking the leaves from the top part of the plant will reduce the harvest. If it flowers, the plant must be uprooted since it will not produce flavourful leaves.
