A Detailed Guide to Jackfruit Planting Methods and Management Techniques

SummarySite selection and planting: Jackfruit should be planted on flat land or hills, and the soil should be well-drained, deep, and fertile. Planting time: spring from March to April, and autumn from September to November are better for planting. Fertilization: the fertilizer requirement is not large; apply sufficient base fertilizer at the seedling stage, apply quick-acting fertilizer when new shoots grow, and apply organic fertilizer during the fruiting stage. Watering: the water requirement is high during the flowering stage and fruit development stage, and drainage should be noted in the rainy season. Shaping and pruning: pruning is carried out in winter. Fruit thinning and fruit retention: remove inferior fruits every year from March to April.

I. Selection and Planting

Jackfruit is suitable for growing in a warm environment, and the growing temperature should not be lower than 21°C. Jackfruit should preferably be planted on flat land or hills at an altitude below 600 m. It has low requirements for soil and is suitable for planting in fertile, well-drained, deep, slightly alkaline or acidic soil.

II. Planting Time

1. Jackfruit can be planted all year round, and it is generally better to plant in spring from March to April and in autumn from September to November.

2. Before planting, dig the planting holes, place the seedlings so that the root system can spread out, cover with fine soil and press firm, keep them parallel to the ground, and finally water thoroughly and cover with a layer of plastic film.

III. Reasonable Fertilization

Jackfruit has a low demand for fertilizer. At the seedling stage, sufficient base fertilizer should be applied. When new shoots grow, a quick-acting fertilizer can be applied once. During the fruiting stage, to promote the rapid growth of new shoots, an appropriate amount of organic fertilizer or quick-acting fertilizer can be applied, which helps promote flowering and fruiting.

IV. Timely Watering

Jackfruit has a relatively high water requirement during the flowering stage and fruit development stage, so water must be supplemented in time. In other growth stages, moderate watering is sufficient. In addition, in the rainy season, drainage must be carried out in time to prevent water accumulation at the roots, which can cause root rot and affect normal growth.

V. Shaping and Pruning

When the main trunk of jackfruit grows to 1 m, to prevent nutrients from being consumed, all the short branches, overlapping branches, dense branches, and crossing branches that grow out can be cut off. Pruning in winter is generally better. When pruning, 3-4 primary branches can be retained, which helps form a good tree structure.

VI. Fruit Thinning and Fruit Retention

1. During the fruiting stage of jackfruit, in order to ensure the normal growth of good fruit, every year from March to April, all deformed fruits, dense fruits, and other inferior fruits that grow out should be removed. When thinning fruit, it is advisable to retain 3-5 fruits per sq m of tree canopy.

2. To prevent pests and diseases and promote fruit enlargement, at the young fruit stage, foliar fertilizer, insecticide, and fungicide can be mixed evenly and sprayed, about once every half a month. At the fruit-setting stage, a fungicide mixed with an insecticide can be selected and sprayed once a month.

VII. Pest and Disease Control

The main pests and diseases of jackfruit include beetles, longhorn beetles, soft rot, leaf spot, and so on. Therefore, preventive work must be done in advance. If pests are found, chlorpyrifos at 600 times dilution can be smeared on the trunk, or they can be directly caught and killed. For disease control, 1500 times chlorothalonil or 1000 times carbendazim can be used.

VIII. Timely Harvesting

Jackfruit generally basically matures from September to October, and it can be harvested in time according to the specific region and climate.
