Collect fruits in mid-autumn; the best time is while they are still green and before any germination inhibitors develop. Soak them in warm water for several days to clean the flesh off the seeds. Sow into containers and place in a sheltered site or store in a refrigerator and sow in late winter. Germination occurs at 10-15ºC, but is erratic, so keep the seeds until the second spring. It is quicker to graft if only one or two plants are required. It makes a good seed-raised stock at two or three years old. Chip-bud outdoors, 15cm from soil level.
