And growing a black plum tree in your backyard can be a very satisfying experience, as it produces awesome Jamun fruits which are both tasty and beneficial for health. If you take proper minimal required care, your plum tree will continue to bloom and it will produce plums for years.

The Jamun tree can be easily propagated from its seeds; it can also be propagated with other methods like air layering, grafting, cutting, etc. For growing this java plum tree take some of the fruits and remove the pulp or flesh from the plum and let it dry for one day. In the meantime, you can prepare a good potting mix for growing the tree.

For proper growth of the tree, you must ensure planting the seeds in well-drained soil, because these trees grow best in rich soil that does not remain continuously wet. If the soil retains a lot of water, it might cause the roots of the tree to rot. For preparing the potting mix you can take 60 percent normal garden soil, 20 percent fine sand, and 20% organic compost mix.

Fill this potting mix in some small containers or plastic cups, before that make a hole at the bottom and cover the hole with a small grater and then fill the potting mix. Then make a small hole in this potting mix and gently place the seeds in the hole and cover it with some more potting mix.

Make sure your planting site gets indirect sunlight; the black plum tree will need 6 to 8 hours of indirect sunlight each day to grow. Also, water your new tree at regular intervals; newly planted trees need plenty of water for the first few weeks after planting.

You should fertilize the Jamun tree after its first crop of fruit; spread a mild, slow-releasing fertilizer about one foot away from the trunk of the tree. A fertilizer that has equal parts nitrogen, phosphorus, and potassium is recommended for the proper growth of the plum trees.

Pruning the young Jamun tree for the first time will set it in proper shape and encourage further growth of the tree. You should prune carefully, and remove away any affected fruits, twigs, leaves, or flowers.
