+ Ecology

A large tree, native to Burma, India, the Philippines and Sri Lanka, introduced in many other tropical countries and even into the sub- tropics, e. g. southern Australia and Florida. In Uganda it is grown as an avenue, compound or back-yard tree. In some areas it has become naturalized in secondary forests and scrub. It grows best in areas with rainfall over 1,000 mm annually and in well-drained soils, although it can tolerate waterlogging. In Kampala, Jambolan can be found within Uganda Golf course club, Kitante courts, Makerere University, Makerere II Zone C along Buganda road, Kololo hill lane among other places.

The bark contains 13 - 19% tannins. It yields a brown dye that has been used in colouring and preserving fishnets.

The branches are used to whiten the teeth The wood is used for construction, boat building, commercial tea and chest plywood, agricultural implements, tool handles, cart wheels, well curbs and troughs, sleepers, furniture and as props for shafts and galleries in mines. It is also used for building bridges and for making musical instruments, especially guitars.

Seeds, grafting, air layering.

+ Management

Fairly fast growing, pollarding, trimming, coppicing.

+ Remarks

In Uganda, Jambolan has become one of the major cheap fruits and also an important tree for firewood production. Intercropping with banana, coffee and cocoa should be encouraged as well as planting single trees for shade and other uses.
