Star Fruit Trees

Star Fruit Tree

The Carambola is a small to medium sized tree with bushy, evergreen foliage. The fruit has a delicious tangy flavor that resembles an apple, grape and citrus combination and is crisp in texture. The fruit can be eaten fresh and is often used in salads or tropical drinks as a garnish due to its unique star shape. 

Star fruit trees are native to Malaysia, Indonesia and Southern China. They mature to a height of 20-35 feet tall and about 20-25 feet wide. Some of the common varieties of Carambola include: King, Bell, Sri Kembangan, Arkin and Fwang Tung. For mature trees, they are capable of producing up to 200 pounds of fruit a year. Commercial production occurs in Hawaii, Florida, and other tropical regions of the world.

Growing Conditions

These trees grow in Zones 10 to 11, but can also grow in Zone 9 if protected from frost. They thrive in subtropical and tropical climates. If they are exposed to temperatures below freezing, it could kill the tree or prevent future growth. The trees should be planted in full sun and do better in areas that are protected or sheltered from the wind. 

Fertilize

It is recommended that Star Fruit are fed fertilizer four to five times a year using a balanced liquid fertilizer or during the growing season use a slow release granular fertilizer.

Water

Star Fruit does well with regular watering. During the rainy season, additional watering is not needed. 

Soil

Carambola grow faster and produce more fruit in a soil with more organic matter. They require good drainage and the ground around them should not be kept wet for long periods. 

The best type of backyard variety is the Arkin Star Fruit tree because of it’s sweeter flavor.
