Cultivation
Prefers a moderately heavy loam with a generous amount of compost and sand added and a very sunny position. This species is not hardy in the colder areas of the country, when dormant it tolerates temperatures down to between -5 and -10°c. The young growth in spring, even on mature plants, is frost-tender and so it is best to grow the plants in a position sheltered from the early morning sun[K]. Kumquats are sometimes cultivated in China for their edible fruit, there are some named varieties.
Propagation
Seed - best sown as soon as it is ripe in a warm airy position in a greenhouse. When they are large enough to handle, prick out the seedlings into individual pots and grow them on in a greenhouse for at least their first two winters. Plant out in late spring or early summer after the last expected frosts and give some winter protection from the cold for a year or two.
