Establishment
Planting through canopy formationRoots, structure, organic matter
Give young Duku a broad, aerated root zone before pushing rapid canopy growth. Use mature organic inputs in modest split applications.
Crop growing guide
Duku
Lansium parasiticum
A humid-tropical fruit tree that rewards deep organic soil, gentle establishment, and balanced feeding before flowering and fruit fill.
Duku (Lansium parasiticum) develops into a long-lived orchard tree with a relatively slow juvenile phase. Young plants benefit from temporary shade and an evenly moist root zone, while mature trees need better canopy light and dependable water as flowers and clustered fruit develop. Organic mulch helps protect its feeder roots, but must not touch the trunk.
For practical cultivation, Duku needs its light, water, root-zone aeration, and nutrition managed as one system. The guidance below organizes those needs by growth stage; final field or container rates should follow the product label, plant size, local conditions, and soil or media analysis.
Ideal growing conditions
- Light
- Full sun, with temporary protection from severe afternoon heat while young.
- Climate
- Warm, humid tropical conditions with stable temperatures and shelter from strong wind.
- Water
- Deep, regular watering during establishment; even moisture during flowering and fruit fill without waterlogging.
- Soil
- Deep, organic-rich loam with strong drainage and a broad, uncompacted root zone.
- Soil pH
- 5.5–6.5
Nutrition by growth stage
Vegetative growth
Active shoot and canopy flushesBalanced nutrition, leaf area, resilient shoots
Support each Duku flush steadily, then allow shoots to harden. Excess nitrogen can create soft growth and delay reproductive balance.
Flower initiation and bloom
Before buds form through full bloomPhosphorus, potassium, micronutrient balance
Duku needs steady rather than abrupt nutrition as it shifts from shoots to flowers. Avoid a fresh surge of nitrogen at this stage.
Fruit set and fill
From successful set until harvestPotassium, water stability, fruit retention
Maintain even root moisture and potassium availability while Duku carries fruit. Large moisture or salt swings increase stress and fruit loss.
Post-harvest recovery
Immediately after harvest and pruningCanopy renewal, roots, stored reserves
Return organic matter and balanced nutrition after harvest so Duku can rebuild leaves, roots, and reserves for the next cycle.

Match each product to the crop stage and root zone. Final rates should follow the product label, soil condition, and local agronomic advice.
Durian Special Mix
Special organic blend formulated for fruit plant growth and crop quality.
From IDR 28.000 / Kg(Packaging 20Kg)
Recommended for
Fruit set and fill · Post-harvest recovery
Durian Special Mix organic nutrition can support Duku when its use follows crop stage, soil condition, and the product label.
Best timing
Introduce during active growth and the higher-demand stages listed above; avoid a large corrective dose close to harvest or dormancy.
How to apply for this crop
Apply to moist soil around the active Duku root zone, keep material away from stems or crowns, water in, and adjust the amount to plant size and field or container conditions.
General product guidance
Apply around the active root zone or mix into the planting media according to the package label, then water lightly. Adjust the amount to plant size, soil condition, and crop stage.
NPK 5-5-5
Alitura's Reserve
Most Balanced NPK 5-5-5 Organic Nutritional Fertilizer
From IDR 28.000 / Kg(Packaging 20Kg)
Recommended for
Establishment · Vegetative growth
balanced soil-building organic nutrition provides a defensible foundation for Duku without replacing soil or leaf analysis.
Best timing
Use during soil preparation, establishment, or recovery, then reassess before the next growth stage.
How to apply for this crop
Spread evenly through the cultivated root zone or media, mix lightly where appropriate, and never pile fertilizer against Duku.
General product guidance
Use Alitura's Reserve as a base feed at planting and as a top-up through the growing season. As a general guide, work a small handful into the soil around each plant or mix it into potting media before planting, then reapply every 4 to 6 weeks during active growth. For garden beds, broadcast evenly over the soil surface and lightly incorporate, then water in well. Powder works best mixed into soil or media. Always water after applying and adjust the amount to plant size and soil condition.
Mistakes to avoid
- Piling fertilizer against the trunk instead of distributing it through the active root zone.
- Pushing nitrogen during flowering and creating leaf growth that competes with fruit set.
- Ignoring post-harvest recovery and expecting the next crop without rebuilding reserves.
- Do not force young duku trees with concentrated fertilizer or leave their root zone waterlogged.
