Notes

Fruit - usually cooked and used in jellies, preserves etc[1] or used as a flavouring, but it can also be eaten raw. The whole fruit, including the peel, is eaten[2][3]. The fruit is acid whilst the peel is sweet[2][3]. The peel is golden-yellow, smooth, thinner and somewhat sweeter than the oval kumquat, F. margarita[1]. The fruit is rich in pectin and makes excellent marmalades and jellies[4]. Vitamin C content is up to 0.24 mg/cc[4]. The fruit is about 4cm long[5].

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.

Cultivation

Prefers a moderately heavy loam with a generous amount of compost and sand added and a very sunny position[8]. Prefers a pH of 5 to 6[8]. Plants are intolerant of water logging[8].

This species is not hardy in the colder areas of the country, when dormant it tolerates temperatures down to about -5°c[8]. 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 widely cultivated in China for their edible fruit, there are many named varieties[2]. The plant is less vigorous, somewhat thorny and considerably more cold tolerant[1] (the report gives no details of what this is in comparison to!). Kumquats are hardier than the various Citrus species since they cease growth when temperatures drop below 13°c but, for best results, it is best to grow them in a climate where temperatures do not fall lower than between 4 and 10°c[2]. This is because the fruit is sweeter when it ripens in warm conditions[2].
