Abundant Sweet Large Crispy Fruit

Common Names: Arkin Star Fruit, Carambola
Family: Oxalidaceae
Origin: Southeast Asia (cultivated in Florida and tropical regions)

Arkin Star Fruit (Averrhoa carambola) is the most popular star fruit variety in Florida, prized for its sweet flavor, crisp texture, and high productivity. This variety was developed to thrive in Florida’s subtropical climate, producing abundant crops of golden-yellow, star-shaped fruits. The fruit has a perfect balance of sweetness and mild acidity, making it ideal for fresh eating, juicing, and adding to salads and desserts. The grafted Arkin trees are capable of fruiting now, making it an excellent choice for gardeners seeking fast results. In addition to its delicious fruit, the tree’s attractive foliage and manageable size make it a standout in home gardens.

This Carambola variety was hybridized by Morris Arkin, a Washington, D.C. native stockbroker who retired into the fruitful world of horticulture. In reaping the benefits of homegrown life, the Arkin Star Fruit was born.

General Growing Guide for Star Fruit Trees (Averrhoa carambola)

Star fruit trees, also known as carambola, are tropical to subtropical fruit trees prized for their distinctive star-shaped fruit, which is crisp, juicy, and sweet-tart in flavor. Native to Southeast Asia, star fruit trees thrive in warm climates and produce abundant golden-yellow fruits that are rich in vitamin C, antioxidants, and fiber. This guide will help you grow healthy, productive star fruit trees that will bring tropical flavor to your garden.

Climate and Zone Requirements

  • Climate: Star fruit trees grow best in tropical and subtropical climates. They thrive in warm, humid environments with temperatures consistently above 60°F (16°C). Star fruit trees are frost-sensitive and cannot tolerate freezing temperatures. They are best suited for USDA hardiness zones 10-11.
  • Container Growing: In cooler regions, star fruit trees can be grown in large containers and moved indoors during the colder months. Ensure the tree gets plenty of sunlight and warmth while indoors.

Soil Requirements

  • Soil Type: Star fruit trees prefer well-draining, slightly acidic soil with a pH of 5.5-6.5. While they can tolerate a range of soil types, loamy or sandy soils enriched with organic matter, such as compost, are ideal for optimal growth.
  • Drainage: Proper drainage is essential to prevent root rot. Avoid waterlogged soil and ensure the planting area has good drainage. If planting in a container, use a well-draining potting mix.

Planting Star Fruit Trees

  1. Location: Choose a sunny spot that receives at least 6-8 hours of direct sunlight daily. Full sun is crucial for star fruit trees to grow and produce abundant fruit.
  2. Soil Preparation: Loosen the soil in the planting area and mix in organic compost to improve fertility and moisture retention. If planting in a container, ensure the pot has drainage holes and use a well-draining potting mix.
  3. Planting Time: Plant star fruit trees in spring or early summer when the soil has warmed and the risk of frost has passed.
  4. Spacing: If planting multiple trees, space them 10-15 feet apart to allow for their spreading canopy.

Watering

  • Consistent Moisture: Star fruit trees require regular watering to keep the soil consistently moist but not waterlogged. Water deeply and regularly, especially during the growing season and fruiting period.
  • Drought Sensitivity: While star fruit trees are somewhat drought-tolerant once established, they perform best with consistent moisture. Avoid letting the soil dry out completely, especially when the tree is young.

Fertilizing

  • Balanced Fertilizer: Apply a balanced, slow-release fertilizer every 2-3 months during the growing season to promote healthy growth and fruit production. Fertilizers high in nitrogen, phosphorus, and potassium are ideal.
  • Organic Matter: Adding organic compost or well-rotted manure to the soil can help improve soil fertility and provide essential nutrients.
  • Trace Elements: Star fruit trees also benefit from micronutrients like magnesium and iron, which can be supplied through a well-balanced fertilizer or by applying Epsom salts if deficiencies are noted.

Pruning and Maintenance

  • Light Pruning: Regularly prune star fruit trees to remove dead or damaged branches and shape the tree. This helps maintain a manageable size and promotes air circulation, reducing the risk of pests and diseases.
  • Growth Management: Star fruit trees can grow up to 20-30 feet tall, but they can be pruned to a smaller size for easier harvesting, especially in home gardens or containers.
  • Container Growing: For container-grown star fruit trees, ensure the container is large enough to accommodate the root system. Prune roots when necessary and repot the tree into a larger container as it grows.

Sunlight Requirements

  • Full Sun: Star fruit trees need full sun for optimal growth and fruit production. Ensure the tree receives at least 6-8 hours of sunlight daily.
  • Partial Shade: While the tree can tolerate partial shade, too much shade can result in reduced fruiting and slower growth.

Pest and Disease Management

  • Common Pests: Star fruit trees can attract aphids, scale insects, fruit flies, and mealybugs. Regularly inspect the tree for pests and use neem oil or insecticidal soap to manage infestations.
  • Diseases: Star fruit trees are generally disease-resistant but can be susceptible to fungal diseases like root rot and leaf spot if grown in poorly draining soil. Ensure proper drainage and avoid overwatering to prevent fungal issues.

Harvesting Star Fruit

  • Harvest Time: Star fruits are typically ready for harvest when they turn from green to bright golden-yellow. The fruit should be slightly soft to the touch and easily come off the tree when ripe.
  • Harvesting Method: Harvest the fruit by hand or use pruning shears to cut the fruit from the tree. Regular harvesting encourages continuous fruit production throughout the season.
  • Post-Harvest Storage: Star fruits can be stored in the refrigerator for up to two weeks or left to ripen at room temperature for a few days.

    Star Fruit ‘Arkin’

    My newest purchase from Sow Exotic arrived today and I was thrilled. I am always happy with their packaging and the health of the plants when I open the box, and this was no exception.

    The first picture is the tree right out of the box….the second is it after potting up sitting next to some of my previous purchases. (From left to right…Longan, Lychee, mango, and star fruit. The red circles are their second year, and blue are purchased this year. Beautiful!
