Pre-sowing Treatment: Place the seeds in a small container, pour boiling water over them, then leave to soak until the seeds have swelled to double their original size. For any that do not swell after 12 hours, dry them out for 24 hours, then repeat the process.

Sowing Instructions: Sow at any time of the year. Sow in pots or trays on the surface of a moist, good quality seed compost, eg John Innes, mixed 50:50 with vermiculite. Seal in a polythene bag or place in a propagator and maintain an optimum temperature of 18-20C. Germination should take place in 2-8 weeks. Gradually increase ventilation as the seedlings emerge by opening the bag or propagator vents.

Growing Instructions: When the seedlings are large enough to handle, pot up into small pots and grow on in slightly cooler conditions in plenty of light but shaded from direct sunlight. In spring, gradually acclimatise the young trees to outdoor conditions and when large enough plant out in a sunny spot in well drained soil.

Caution: All plant parts toxic if eaten
