Java plum young plant

It usually takes between 10 and 15 days for seeds to germinate. During spring or the monsoon season, seedlings are transplanted.

It is not necessary to prune jamun on a regular basis. After a few years, the twigs and branches that have crossed each other are removed. For best results, allow the branches of the plants to grow above 60-100 cm from the ground.

The planting process

Java plum trees are planted in spring between February and March. 

Generally, trees planted in February-March suffer from mortality due to the unfavorable weather conditions in May and June soon after planting, so the latter season is considered better.


Manure is generally not applied to Java plum trees. In spite of the fact that they require manuring and are responsive to it, they can survive quite a bit of neglect. During planting season, apply 19 kg of manure per tree, and 75 kg as the tree bears fruit.

Fruit-bearing trees graft or bud after 6 to 7 years, and seedlings take 8 to 10 years. Trees grow more vegetatively in rich soils, delaying fruit production. Trees with such a tendency shouldn’t be fertilized in September and October.

The training and pruning process

This tree does not require regular pruning. The branches are crossed and the dry twigs are removed in later years. A plant’s framework of branches should develop above 60 to 100 cm from the ground during training.

Yield and harvest

A seedling plant bears fruit in 8 to 10 years, whereas a grafted plant bears fruit in 6 to 7 years. In June and July, the fruit ripens. Deep purple or black color characterizes ripe fruit at full size. It is best to pick the fruit when it is ripe, since it cannot be preserved on the tree. Hand-picked ripe fruits are slung on the shoulders. Fruits should be handled carefully to avoid any damage.

Approximately 80 to 100 kg of fruit are produced per year from a seedling tree and 60 to 70 kg from a grafted one.

Coimbatore is the only place where this caterpillar can be found. Trees may become defoliated after being infested with the insect. 

Water supply

The interval between irrigations can be greatly reduced as Java plum plants grow. During the first few years of a tree’s life, it is necessary to irrigate it eight to ten times. In May and June, mature trees require about half that number of applications. The soil may need to be irrigated only occasionally during the autumn and winter months. As a result, the trees will also be protected from frost damage in the winter.
