• Botanical Classification:
  • Kingdom: Plantae
  • Clade: Tracheophytes
  • Clade: Angiosperms
  • Clade: Eudicots
  • Clade: Rosids
  • Order: Malpighiales
  • Family: Clusiaceae
  • Genus: Garcinia
  • Species: G. humilis
• Origin and History: The Achacha has been cultivated for centuries by indigenous communities in the Amazon. It wasn’t until relatively recently that it gained significant commercial attention, particularly in Australia, where it has become a popular niche crop. A key figure in its Australian introduction is Bruce Hill, who began large-scale cultivation in the early 2000s.
• Tree Characteristics:
  • Size: Typically grows to a height of 5-12 meters (16-40 feet) in its natural habitat, but can be kept smaller through pruning in cultivation.
  • Leaves: Evergreen, glossy, dark green leaves with an elliptical shape.
  • Flowers: Small, white or cream-colored flowers that are typically pollinated by insects and birds.
  • Fruit: The fruit itself is the star of the show. It’s a small, round or oval-shaped drupe, about the size of a large egg (roughly 6cm long and 4cm in diameter). The skin is a vibrant orange-red when ripe, and the flesh is white, juicy, and has a unique sub-acid, refreshing flavor. It typically contains one to four seeds.
• Fruit flavor and texture: The flavor is complex, having sweetness, tartness, and a hint of bitterness. Described as refreshing and sorbet-like.
• Nutritional Value (per 100g serving – approximate values): (Note: Nutritional content can vary based on growing conditions and ripeness.)

Growing Your Own Achacha Fruit Tree: A Step-by-Step Guide

Step 1: Climate and location considerations

• Ideal Climate: The Achacha thrives in tropical and subtropical climates with high humidity and warm temperatures. It requires a minimum temperature of around 5°C (41°F) to survive, and ideally, temperatures should consistently remain above 15°C (59°F) for optimal growth.
• USDA Hardiness Zones: Achacha trees are best suited for USDA hardiness zones 10b-11. In the US, this limits cultivation primarily to South Florida, Hawaii, and potentially some sheltered microclimates in Southern California.
• Sunlight: Achacha trees need full sun for at least 6-8 hours per day for best fruit production.
• Soil: Well-draining soil is crucial. Achacha trees do not tolerate waterlogged conditions. A slightly acidic to neutral pH (6.0-7.5) is preferred. Sandy loam or loamy soil amended with organic matter (compost, aged manure) is ideal.
• Protection from Wind: Strong winds can damage the tree and its fruit. Planting in a sheltered location or providing windbreaks is recommended.

Step 2: Obtaining your Achacha Fruit Tree

• Purchasing a Tree: The most reliable way to start is by purchasing a young tree from a reputable nursery. This ensures you get a healthy, disease-free plant. Gardencenterpoint.com can help you locate nurseries specializing in tropical fruit trees in your region or those that ship nationwide. We provide links to trusted vendors.
• Growing from Seed (Challenging): While it’s possible to grow Achacha from seed, it’s not recommended for beginners. Germination rates can be low and unpredictable, and it can take many years (7-10 years or more) for a seed-grown tree to produce fruit. Seed-grown trees may also not produce fruit that is true to the parent.
• Grafting and propagation: Grafting onto suitable rootstock is best for consistency and early fruiting.

Step 3: Planting your Achacha Tree

• Timing: The best time to plant is during the warm season, typically in spring or early summer, after the risk of frost has passed.
• Spacing: If planting multiple trees, space them at least 6-8 meters (20-26 feet) apart to allow for adequate growth and air circulation.
• Planting Procedure:
  1. Dig a hole twice as wide and as deep as the root ball of the tree.
  2. Gently remove the tree from its container, being careful not to damage the roots.
  3. Place the tree in the hole, ensuring that the top of the root ball is level with the surrounding soil.
  4. Backfill the hole with the amended soil, gently firming it around the roots.
  5. Water thoroughly after planting.

Step 4: Watering and fertilizing

• Watering: Achacha trees require consistent moisture, especially during the growing season and fruit development. Water deeply and regularly, but avoid overwatering, which can lead to root rot. A good rule of thumb is to water when the top inch of soil feels dry to the touch. Mulching around the base of the tree (keeping the mulch away from the trunk) helps retain moisture.
• Fertilizing: Young trees benefit from regular fertilization with a balanced fertilizer (e.g., 10-10-10 or a similar formulation designed for tropical fruit trees). Apply fertilizer according to the manufacturer’s instructions, typically every 2-3 months during the growing season. Mature, fruit-bearing trees may require less frequent fertilization. A soil test can help determine specific nutrient needs.

Step 5: Pruning and training

• Pruning: Pruning is important for maintaining the shape and size of the tree, promoting air circulation, and encouraging fruit production.
  • Young Trees: Prune to establish a strong central leader and well-spaced scaffold branches.
  • Mature Trees: Remove any dead, damaged, or crossing branches. Thin out the canopy to allow for better light penetration. Light pruning can be done after harvest.
• Training: Young trees may benefit from staking to provide support, especially in windy areas.

Step 6: Pest and disease

• Common Pests: Achacha trees are relatively pest-resistant, but they can be susceptible to some common pests, including:
  • Fruit Flies: These can be a significant problem in some areas. Monitor for fruit fly activity and use appropriate control measures, such as traps or organic sprays.
  • Scale Insects: These can be controlled with horticultural oil or insecticidal soap.
  • Mealybugs: Similar to scale insects, these can be treated with horticultural oil or insecticidal soap.
• Common Diseases: Achacha trees are generally disease-resistant, but they can be affected by fungal diseases in humid conditions.
  • Anthracnose: This fungal disease can cause leaf spots and fruit rot. Good air circulation and proper sanitation (removing fallen leaves and fruit) can help prevent anthracnose.
  • Root Rot: This is usually caused by overwatering or poorly draining soil. Ensure proper drainage and avoid overwatering.
• Integrated Pest Management (IPM): We recommend using an IPM approach, which emphasizes prevention, monitoring, and the use of least-toxic control methods.

Step 7: Harvesting your Achacha Fruit

• Maturity Signs: The fruit is ripe when it turns a vibrant orange-red color and yields slightly to gentle pressure. The skin may also develop a slightly wrinkled appearance.
• Harvesting Technique: Gently twist or cut the fruit from the tree, being careful not to damage the branches or the fruit.
• Storage: Achacha fruit has a relatively short shelf life at room temperature (a few days). It can be stored in the refrigerator for up to 2-3 weeks.

Uses and Benefits of Achacha Fruit
