How it is grown
Plants can be grown from seed. The seed has a coat which prevents water entering so this needs to be cut with a small nick. Another method is to soak the seed to water at 60°C 3 times over 3 days. Seed then planted and placed in the sun will germinate in 1 to 4 weeks. Soft wood cuttings can also be used.
Trees grow slowly about 0.5 m a year. Trees grown from seed bear fruit in 7-10 years. The fruit stalks ripen late in the season and can be used similarly to raisins. They can be stored in a cool dark place for 2 months.
