Carambola origins and characteristics

Star fruit (averrhoa carambola) or carambolier is a fruit tree of the oxalidaceae family. Native to the tropical regions of Asia, Malaysia and Indonesia, it is now cultivated in most tropical regions of the globe.

This tropical species produces fruits throughout the year, in its natural environment. This Asian tree which can reach 9m in height is one of the only ones to produce as many fruits per tree: from 50 to 300kg!

Carambolas are tropical fruits of green to orange-yellow color. Edible, they are very fresh and appreciated for their more or less tangy taste (depending on the variety). In France, they are often used as a decorative element, thanks to their star shape.

Carambola plantation

Despite its exotic origins, the carambol tree adapts to most climates and soils as long as it is well drained. Install it in a heated and bright greenhouse, because it fears the cold and appreciates the heat.

Sow the carambola seeds in the spring, in a greenhouse with a temperature varying between 20 and 22 degrees. The day before sowing, water the soil in the place provided.

Planting can take place from the beginning of spring, until at least June. Choose a pot suited to its size, so that the carambola tree is not cramped. Do not forget to have a drilled pot to ensure good drainage of the soil.

To ensure a good yield, it is advisable to plant at least two and different varieties so that pollination is perfect.

Carambola tree maintenance

Very easy to maintain, star fruit does not require a draconian interview. It requires just a little more water in the first year of planting. However, make sure that the carambola tree never runs out of water, especially during the flowering period or during the summer season. The potting soil must remain cool, moist but must be well drained.

The carambola tree likes rich substrates. Do not hesitate to bring it fertilizer to promote its development.

Finally, just prune your carambol tree correctly to give it an ideal shape.

Carambola harvest

Star fruit does not give its first fruits of the same name at least 3 years after planting. It is then necessary to wait about fifty days between the flower and the fruit which turns golden yellow when ripe.

In our latitudes, the star fruit harvest generally takes place at the end of the year, in December. Let them finish maturing indoors, at room temperature. These can be kept for around 1 month under these conditions.

Carambola diseases, pests and parasites

The main parasites that can attack your carambolier are mealybugs, aphids or even red spiders.

Carambola cooking

The different star fruit recipes can be sweet or savory. This star shaped fruit when cut has a sweet and tangy taste. It is most often known for its use in pastry or dessert decoration.

Eating star fruit is also a guarantee of replenishing vitamin A and C as well as trace elements.

Other use of star fruit

Thanks to its acidity, star fruit is also practical because, by rubbing its pulp on a metallic object, it becomes clean again. It can also be used on persistent blood stains.
