It also contains dietary fiber and antioxidants, making it a healthy addition to the diet.

Growing Conditions

Climate: Thrives in tropical regions with high humidity and consistent rainfall.

Soil: Prefers well-drained, slightly acidic soils rich in organic matter.

Sunlight: Requires partial to full sunlight.

Watering: Needs regular watering but avoid waterlogging.

Uses

Culinary: Often eaten fresh, but can also be used in jams, desserts, and syrups.

Traditional Medicine: In some cultures, the fruit and its seeds are used for treating digestive issues and fever.

Wood: The tree's wood is valued for making furniture and tools.

Here are some tips for cultivating langsat (Lansium domesticum):

1. Selecting a Variety

Langsat: Smaller, more sour fruit, thinner skin.

Duku: Larger, sweeter fruit, thicker skin, more resistant to pests.

Choose a variety based on your taste preference and local growing conditions.
2. Site Selection

Climate: Needs a tropical climate (temperature range: 25–35°C or 77–95°F).

Sunlight: Prefers partial to full sunlight but benefits from some shade during extreme heat.

Protection: Avoid areas prone to strong winds, as the tree is delicate.
3. Soil Preparation

Type: Use well-draining, slightly acidic soil (pH 5.5–6.5).

Amendments: Enrich soil with organic matter like compost or aged manure.
4. Planting

Spacing: Plant trees 8–10 meters (26–33 feet) apart to allow room for growth.

Depth: Dig a hole twice the size of the root ball, ensuring the graft union (if any) is above soil level.
5. Watering

Frequency: Water regularly, especially during dry spells, but avoid waterlogging.

Mulching: Apply mulch around the base to retain moisture and regulate soil temperature.
6. Fertilization

Timing: Fertilize 2–3 times a year.

Type: Use balanced fertilizers (NPK 10-10-10) during early growth and switch to higher potassium (K) during fruiting.

Organic Options: Compost or fish emulsion works well.
7. Pruning and Maintenance

Pruning: Remove dead, diseased, or overcrowded branches to improve air circulation and light penetration.

Weeding: Keep the base of the tree weed-free to reduce competition for nutrients.
8. Pest and Disease Management

Common Pests: Scale insects, mealybugs, and fruit borers.

Diseases: Watch for anthracnose and root rot.

Prevention: Use neem oil or insecticidal soap, and ensure proper drainage to prevent fungal issues.
9. Harvesting

Time to Fruit: Trees typically start bearing fruit after 10–12 years if grown from seed, or 5–7 years if grafted.

Ripeness: Harvest when the skin turns yellowish-brown and the fruit detaches easily.
