Description
Kumquat trees bear small citrus fruits (about the size of olives) that are sweet with a bit of a tart taste to them. Unlike other citrus, they can be eaten with the skin. They can also be juiced for a refreshing drink.
The trees are self-pollinating, so you only need one to bear fruit.
Kumquats have lots of vitamin C, fibre, antioxidants, and a little vitamin A. They are free of cholesterol and low in sodium. They really are a healthy, tasty snack.
Position
Kumquat trees are easy to grow in full sun. They even do well at the sea and, unlike other citrus fruit, can withstand winter temperatures as low as -8° Celsius. Give each tree about 3 to 4 metres of space around it.
Soil Type
Kumquats can tolerate most soil types with good drainage.
Size
This tree grows to a height of between 2 and 4 metres.
Watering
The soil should be kept moist (but not soggy) once the tree has been transplanted. They are susceptible to root rot. An established tree needs watering weekly if there’s been no rain.
Mulch
Mulch well to keep the soil from drying out too quickly. Use organic material like grass cuttings or straw.
Fertilising
No fertiliser is required for the first 3 months. After that, use a fertiliser specifically for citrus trees.
Pruning
Kumquat trees don’t require pruning unless the tree grows too large and has long, skinny branches growing straight up. You can also cut away any damaged or dead wood to allow the sun and light to enter the centre of the tree. Prune it after fruiting and before it blooms in spring.
Container Growing
Kumquat trees can be grown in large containers if the pot has good drainage. You can even drill extra-large drainage holes and cover the holes with pebbles or a window screen to keep the soil from falling through. Raise the pot off the ground to improve drainage and air circulation. Cover the roots with a thick layer of mulch, grass, leaves, or bark in winter
Harvesting
Kumquats have to ripen on the tree before being picked, which may take weeks. The only way to know if they’re ready is to sample one. If it isn’t yet ripe, wait a week or so before trying another one. They will begin to fall from the tree when they are overripe.
