In general, seedlings grow slowly and have low survival rates. This means that special care is needed in the early years. Direct sowing has been tried in Tanzania, but survival of seedlings was low, up to only 26% after 10 years. Once established however, which is usually after 1 - 3 years, the young trees can grow fairly fast[

The heartwood is pale brown, darkening to golden brown upon exposure; distinctly demarcated from the 5 - 15cm thick band of greyish white sapwood. The grain is interlocked; texture moderately coarse to coarse; the wood has some stripe or ribbon figure and is lustrous. The wood is medium-weight; fairly soft to moderately hard; not durable to moderately durable - it shows moderate resistance to termite attacks, but is susceptible to powder-post beetle, pinhole borer and marine borer attacks. However, the wood is reportedly durable in fresh water, and is for that reason much used for making canoes in Lake Victoria. It air dries and kiln dries satisfactorily, with little distortion but with some risk of checking. After drying, the wood is moderately stable in service. It is easy to saw, but with some tendency to split due to growth stresses; it works fairly easily by hand and machine tools, but mortising and boring are somewhat difficult; a cutting angle of 10° and sharp edges are recommended for planing of quarter-sawn stock, but for flat-sawn pieces an angle of 30° is sufficient; the use of a filler is needed to obtain a good finish; it holds screws and nails well, but there is a tendency to splitting; pre-boring is recommended; it glues more or less satisfactorily and peels well. The boles have a tendency to split during felling operations. Freshly harvested logs are liable to insect attacks and should be removed from the forest soon after felling to avoid damage to the wood.
The wood is used for tool handles, implements, carpentry, joinery, cabinet work, doors, door frames, bridges, boat building, vehicle bodies and fencing. It is suitable for light construction, flooring, interior trim, boxes, crates, veneer and plywood. It is used traditionally to make dugout canoes[
