In the early year of planting there were large space between plants, the intercropping was easy with legumes and vegetables. Common culture practice like training and pruning generally not require to jamun tree, but dry branches should be removed. The insect which cause damage to jamun tree is white fly, leaf eating cater pillar. Jamun fruit mainly damaged by pest like squirrels and bird like parrots and crows. In jamun tree anthracnose is common disease, use of spray with Bordeaux moisture and Dithane. Jamun tree pollinated by honey bees, houseflies and wind, but maximum fruit set can be obtaining by hand pollination. Heavy flowers and fruit drop within 3 -4 weeks after blooming. Fruit drop can be reducing by the spray of GA3.

Jamun is harvested in monsoon season. Jamun tree start fruit bearing after 8–10 years of planting and continues till the plant is 50-60 years old. Fruit ripen in June-July, the harvesting time is short and limits for 30-40 days. Jamun color is dark purple and oval. Fruit is fleshy and having a hard seed inside.

Jamun fruits are enjoyable raw and maybe into tarts sauces and jam. Jamun juice is often comparable to grapes juice. Jamun fruits big losses during cultivation, harvesting and in processing because untrained and unorganized processing. At normal temperature jamun fruit stored for 2 days. Jamun fruit can be stored at 85-95 % precooled and packed into polythene bags up to 3 weeks.  If we follow the above instruction we can get a good profit from our orchard.
