Durian (Seedling) Fruit Plant

The Durian (Durio zibethinus) is the fruit of several tree species belonging to the genus Durio. Often called the "King of Fruits," durian is one of the most famous tropical fruits, prized for its rich, creamy flesh and unique flavour. The name "durian" is derived from the Malay-Indonesian word "duri", meaning "spike," referring to the fruit's distinctive thorn-covered husk.

Durian fruits are large, ovoid to ellipsoid in shape, and can weigh up to 5 kg. They have a thick, spiny outer shell that is usually olive green in colour. Durian is well known for its strong aroma, which people either love or dislike. Many enjoy its sweet, rich, creamy, and filling taste, while others find its pungent smell similar to rotten onions. However, once the aroma is accepted, the unique flavour makes for an unforgettable eating experience.

Durian seeds are small, round to oval-shaped and resemble jackfruit seeds. When boiled, the seeds are edible and have a mild flavour similar to boiled jackfruit seeds, although they are often discarded.

MAINTENANCE OF THE PLANTATION

Once a plantation has been established, regular maintenance is essential for healthy tree growth and maximum fruit production. Protect the trees from extreme weather, insects, fungal diseases, and animals. Proper orchard management, including regular watering, fertilizing, pruning, and weed control, helps maintain healthy and productive trees.

FERTILIZING

Newly planted durian trees should be fertilized lightly once or twice during the first year, and thereafter 3–4 times annually. A balanced fertilizer such as 6-6-6-2 or 8-3-9-2 is commonly recommended for healthy vegetative growth and fruit production.

WATERING AND WEED CONTROL

Young durian trees require regular watering until they become fully established. During dry weather, water mature trees deeply every 1–2 weeks, or more frequently in hot climates if necessary.

Apply mulch around the base of the tree to conserve soil moisture and suppress weeds. Keep an area of at least 1.5 metres around the tree free from weeds to reduce competition for water and nutrients.

PRUNING AND SHAPE OF THE TREE

Proper pruning is an important part of successful durian cultivation. Formative pruning should be carried out during the first few years after planting by removing excess trunks, upright branches, water shoots, and overcrowded branches.

Allow only a single main trunk to develop. Proper pruning improves sunlight penetration, air circulation, and overall tree health while encouraging better fruit production.

PEST & DISEASE MANAGEMENT

Like all fruit trees, durian has the potential to be affected by insects and diseases depending on climate and growing conditions. Proper maintenance, including watering, fertilizing, pruning, weeding, spraying when necessary, and orchard sanitation, helps minimize most pest and disease problems.

HARVESTING YOUR DURIAN FRUIT

Durian fruits generally mature 125–135 days after flowering, while some varieties mature within 110–116 days after anthesis. The best eating quality is usually achieved about 4 months after flowering.

Signs of maturity include dark brown spine tips, clearly visible grooves between the spines, soft and flexible fruit stalks, swollen stalk joints, and the characteristic strong aroma. Harvest fruits by cutting the stalk with a sharp knife while the fruit is still attached to the tree. Avoid allowing fruits to fall naturally, as this may reduce fruit quality.

PLANTING INSTRUCTIONS

1. Plant your durian tree where it receives full sunlight for healthy growth and maximum fruit production.

2. Durian grows well in moist, well-drained, fertile soils rich in organic matter with an ideal soil pH of 5.0–6.5. Deep loamy or silty soils are best suited for cultivation.

3. For commercial orchards, a spacing of 10–12 metres between trees is generally recommended.

4. For boundary planting or hedges, maintain a spacing of 1–1.5 metres. For exclusive plantations, a spacing of 2 m × 2 m may be adopted where appropriate.

5. In home gardens, maintain a minimum distance of 3 metres between the durian tree and other fruit plants.

6. 100% sunlight is ideal, although young plants can tolerate up to 50% partial shade.

7. During dry weather, water every 2 days immediately after planting. After one month, water every 7–10 days during the first year.

8. Avoid applying chemical fertilizers immediately after planting. If required, apply small quantities (below 100 g) only after 2–3 months, along with adequate irrigation.

9. Do not overwater or allow standing water around the root zone, as this can damage the roots and cause poor plant growth.

Ideal for: Home Gardens, Tropical Orchards, Exotic Fruit Collections, Agroforestry Systems, and Commercial Durian Cultivation.
