• From seed: sow fresh whenever possible.
• Soak in lukewarm water for 12-24 hours before sowing into a well-draining seed mix, and maintain at 25-30°C.
• Germination takes anywhere from 2-8 weeks.
• Other methods: grafting or budding onto disease-resistant rootstock is the standard commercial approach, reducing the juvenile period and controlling tree size.
• Semi-hardwood or hardwood cuttings also work with rooting hormone and high humidity, and air-layering suits species that root poorly from cuttings, wound a branch, apply rooting hormone, and wrap in moist sphagnum moss.
• In containers: it can be grown for years in a large pot (30-50 litres) with excellent drainage, a quality potting mix with added perlite, and repotting every 1-2 years.
• It needs maximum light to fruit, a south-facing window, conservatory, or greenhouse, plus warmth (minimum 15°C) and humidity, misting or a humidity tray helps.
• Regular pruning keeps it compact and productive, and indoor plants may need hand-pollination since natural pollinators won't be present.

• The fruit is eaten fresh or dried, sweet but slightly astringent.
• The seed kernels yield a pale yellow oil (about 25% oil content) known as rayan oil, and the bark is added to palm sugar to slow fermentation.
• Its hard, tough wood is prized for heavy-duty equipment like sugar mills and oil presses.
