Stellite-tipped sawteeth and tungsten- carbide-tipped cutting tools are recommended. The wood planes fairly easily with a smooth finish. It holds nails and screws well, but pre-boring is needed. The gluing properties are poor to satisfactory. The presence of saponins has been reported for the wood, which contributes to the resistance to fungi[

Propagation

Seed - it has a thick and hard seed coat and shows a dormancy of 2.5 - 12 months before germinating. Germination rate may be up to 40%, but is often lower; the germination rate of depulped seeds is lowest, up to 9%. Under experimental nursery conditions, the survival rate of seedlings was 100% after 18 months. Seedlings grow slowly. After germination, growth of aerial parts stops for about 2 months, after which seedlings grow at a rate of 1cm per month, reaching an average height of 25cm after 18 months and 36cm after 29 months[
