Growing Finger lime, Australian Finger Lime
Cultivation: Plants can be grown from seed. Seed germination is erratic. Seeds do not breed true to type and seed from one plant can give a range of fruit colours. They can be grown from cuttings on a heat bed but rooting is slow and can take 6 months. They can be budded onto citrus rootstocks. Because the buds are small this takes some skill to be successful.
Edible Uses: The fruit can be used fresh or for processing into jams, jellies, marmalade etc.
Production: Plants are slow growing. Seedling trees do not bear true to type. The entire range of fruit colours can develop from seed from a single fruit. Seedling trees can take 5 to 17 years to produce fruit. Flowering and fruiting can occur several times throughout the year. Up to 186 g of fruit per tree have been harvested from wild trees. Fruit from natural populations vary considerably in shape, size, colour, seediness and acidity. A fruit weighs about 7-42 g at maturity.
