Techniques of planting and caring for Thai jackfruit

Thai jackfruit tree is an easy-to-grow, low-care variety, without the use of pesticides, but with high yield. The jackfruit is yellow in color and has a sweet, crunchy texture. Learn how to plant and care for this Thai jackfruit tree with Agri!

Technique of planting jackfruit trees

1. Land for planting

In Vietnam, jackfruit can be grown in almost any place, even in nutrient-poor soils. Choose soil for planting in a dry, well-drained place, without prolonged waterlogging. The place where jackfruit is planted must have enough water to irrigate for the tree to grow and develop.

In the delta and lowland areas, jackfruit is only grown in the ground with a solid embankment and must be raised in beds 30 – 80cm high, depending on the height and 1.3 – 1.5m wide. At the same time, create a trench 30-40cm wide to prevent waterlogging in the rainy season.

Dry the pit for 5-7 days before applying fertilizer and backfilling. When filling the hole, bring the topsoil to the bottom, the bottom soil layer is mixed with the fertilizer to fill the top. Note when planting, do not let the roots come into direct contact with the fertilizer. Depending on the slope, dig planting holes as follows:

– Flat land must be cut into ditches at least 30-40cm deep (depending on water level in each place) to prevent waterlogging in the rainy season. Dig a hole 40 x 40 x 40 cm deep and cover 40 – 70 cm high.

– The soil has a slope of about 5%, no need to fill with tissue, just dig a hole with dimensions of 40 x 40 x 40cm.

– The slope is higher than 7%, dig a hole 40 x 40cm in size and 60cm deep.

Each cavity can be mixed: 0.5kg of lime powder, 0.3kg of superphosphate fertilizer, 10kg of manure or coir, bean pods, rotting rice husks…

2. Prepare seedlings

Select grafted seedlings in 11 x 25cm PE bags. Plant height should be at least 35-40cm. Rootstock diameter 0.5cm. Plants grow well. No pests. No broken tops, no yellowing of leaves.

3. Planting density

Planting thick: Distance: 5m from the tree; rows 6m apart.

Planting sparsely: The tree is 6m away from the tree; rows 7m apart.

Barren soil should be planted thickly, good soil should be planted thinly. Currently, people tend to plant thickly to increase production, thereby shortening the payback period. Then apply the method of pruning or pruning.

4. How to grow Thai jackfruit tree:

Tear off the shell of the plastic bag. Cut off the twisted roots in the pot (if any). Use a hoe to open the hole enough to place the potted plant, fill it with soil, lightly compress it, and stick the stake to keep the seedling straight. Irrigation, root cabinets with straw, straw, rice husk, sawdust. Note, when planting, it is necessary to rotate the grafted eye towards the main wind direction to avoid splitting the graft.

Taking care of Thai jackfruit tree

In order for the tree to quickly bear fruit, high yield, and good quality, the care is especially important. Caring for jackfruit trees is not only applying simple techniques but also applying experience.

How to take care of Jackfruit is divided into two periods: the basic construction period of about 3 years – the time when the tree is finished planting until the fruit is stable and the period of economic exploitation from the fourth year onwards.

The second period is a period that requires a lot of experience to handle fruit and market fluctuations. This process is concerned with yield, quality and consumption of fresh and processed products.

Cover the roots to keep moisture

When planting is finished, use available materials such as straw to cover the base to cover weeds. At the same time prevent erosion in the rainy season and keep moisture in the dry season.

Irrigation water

The first month after planting, hot and dry climate needs regular watering every 2-3 days. After that, it can be watered every 4-5 days. From the second year onwards, water the plants in the new period of fertilizing and the months when they are too dry.

Note: Jackfruit is very afraid of waterlogging, so it is in the rainy season. People need to check the canals and sewers and have a plan to prevent waterlogging for the garden.

Grass treatment

Periodically weed around the base. Plow and care 3 times a year. The first year plow 0.4m from the root, the second year 0.6m.

In the highlands, at the beginning and middle of the rainy season, plowing is horizontal compared to the slope, to limit rainwater washing away the soil. At the end of the rainy season, you should plow down the slope to return to the land.

From the 3rd year, weeding around the base only or plowing in rows when necessary. Grass should be retained to help create a stable microclimate and cover the soil surface.

Pruning to create canopy

– Helps the tree to grow in balance, the level I branches (horizontal branches) are evenly distributed. It is necessary to remove diseased branches, old branches, toothpicks, branches that grow in the wrong direction, harmful branches. Pruning should be done when the tree is about 1m tall or more. When the tree is young, pruning branches to create canopy 2-3 times/year. The tree grows once a year when the fruit is harvested. This helps the plant concentrate nutrients and regain strength after a bountiful season.

– How to prune: Cut off branches close to the ground, branches grow parallel to the main trunk axis. Only keep level 1 branches about 40cm or more from the base. Keep branches growing in different directions to create an even canopy. The upper branch is about 40-50cm away from the lower branch, forming a layer, each layer is not more than 5 branches of level 1. Prune away branches of level 2, level 3… for the tree to be both beautiful and airy.

Pruning is one of the measures to help the Thai jackfruit tree concentrate nutrients to develop the necessary branches. As a result, it helps Thai jackfruit trees increase productivity, prevent pests effectively and bring beauty.


Organic fertilizers: Including all kinds of manure, green manure, garbage, coir or rotted rice husk … used for plants to help loosen soil, is a good environment for beneficial microorganisms to decompose organic matter. to form humus for plants.

Dosage: More or less depending on the age of the plant.

How to fertilize: Must dig deep around or a part of the canopy to fertilize.

Indicators Time of application The amount of fertilizer The distance from the base Fertilization trench (depth x width)

First year: Fertilize before planting 0.3 – 0.5kg of lime + 3kg of poultry manure or 5kg of biogas waste. Fertilize 2 times (1 month after planting and 3 months after planting). Each time apply 0.3kg of super Particle + 0.3kg of NPK Buffalo head 20-10-15+TE. Create a trench 30cm deep, 20cmx20cm wide.

2nd year: Fertilize 2 times in May and November. The amount of fertilizer 1 time / 1 root: 3kg microorganic fertilizer + 0.5kg NPK Buffalo head 20-10-15-TE. Make a trench 80cm deep, 25cm x 20cm . wide

From the 3rd year: Fertilize according to the needs of the tree, healthy plants fertilize less, and weak plants fertilize more. On average, each root fertilizes 5-9kg of poultry manure + 0.5kg of lime powder + 0.5-0.7kg of Potassium chloride or 5kg of microbial organic fertilizer + 1.5kg of NPK Buffalo head 16-16-8. Fertilize when the tree is about to bear fruit and after harvesting the first fruit. Fertilize according to the trench dug under the tree canopy and cover with soil.

Pest control on Thai jackfruit tree

* Stem borer: The caterpillar lays eggs on the young leaves, the young fruit then burrows into the stem. Trees with stem borers will appear deep wood humus extruding from the trunk hole, the root.

Use Regent 800 EG or Furadan 3H to mix with garden soil to seal the extrusion hole. Periodically every 10 days / 1 spray of insecticide chlorophyll (use the drug without worrying about overdose and do not need isolation period).

* Fruit borer: Causes young jackfruit to fall. Pests often damage the junction between fruit and fruit and fruit and stem. Pesticides should not be used for control spraying. It is best to cover the fruit early with a plastic bag right after the tree ends physiological fruit drop.

* Fruit flies: Flies often lay eggs on old fruits, causing fruit rot. The optimal way: use a white plastic bag (with perforated holes for venting) to cover the fruit. Combined periodic spraying of chlorophyll insecticides.

Harvest stage

Thai jackfruit tree

After 3 years of planting, the jackfruit tree will begin to bear fruit. From flowering to mature fruit about 5 months. Old jackfruit fruit spines will stretch, the rind turns from young green to yellow green. There is liquid and clear latex, clapping your hands on the face of the fruit has a popping sound. If transporting far away, old fruit will be collected. If you collect the fruit and eat it right away, wait for the fruit to smell good. Harvest fruit too early, young fruit will be of poor quality. Autumn too late is easy to rot.
