Edible Uses

Edible Parts: Fruit
Edible Uses: Pectin

Fruit - raw or cooked[183]. They can also be used in jellies, preserves etc or as a flavouring[183]. The whole fruit, rind as well, is eaten raw. It is best to first squeeze and massage the fruit in order to combine the flavours of the flesh and the rind[183]. After ripening the fruit gradually loses water content, becomes richer in flavour and is then at its best for making preserves[183]. The fruit is up to 4cm in diameter[200]. The fruit is rich in pectin, the inner peel containing about 10%[218].

Now available: PLANTS FOR YOUR FOOD FOREST: 500 Plants for Temperate Food Forests and Permaculture Gardens.

An important new book from PFAF. It focuses on the attributes of plants suitable for food forests, what each can contribute to a food forest ecosystem, including carbon sequestration, and the kinds of foods they yield. The book suggests that community and small-scale food forests can provide a real alternative to intensive industrialised agriculture, and help to combat the many inter-related environmental crises that threaten the very future of life on Earth.

Cultivation details

Prefers a moderately heavy loam with a generous amount of compost and sand added and a very sunny position[200]. Prefers a pH of 5 to 6[200]. Plants are intolerant of water logging[200]. This species is not hardy in the colder areas of the country, when dormant it tolerates temperatures down to between -5 and -10°c[200]. 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[200]. They are hardier than the various Citrus species since they cease growth when temperatures drop below 13°c but, for best results, they are best grown in a climate where temperatures do not fall lower than between 4 and 10°c[3]. This is because the fruit is sweeter when it ripens in warm conditions[3].

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.
