Other Uses

The heartwood is light yellow to reddish-brown; it is not clearly demarcated from the 5 - 10cm wide band of sapwood. The texture is coarse; the grain straight or interlocked. The wood is heavy, hard, elastic, and very durable, being resistant to attacks by fungi, dry wood borers and termites. The wood seasons slowly with a high risk of checking and distortion, once dry it is poorly stable in service. It works well with normal tools; nailing and screwing are good, though pre-boring can be helpful in the hard wood; gluing is correct. It is used in general construction for purposes such as beams, scantlings, laths, door and window jambs; for making furniture, door and window frames, flooring blocks, lathe work, boxes and crates etc[

Like many species within the family Fabaceae, once they have been dried for storage the seeds of this species may benefit from scarification before sowing in order to speed up and improve germination. This can usually be done by pouring a small amount of nearly boiling water on the seeds (being careful not to cook them!) and then soaking them for 12 - 24 hours in warm water. By this time they should have imbibed moisture and swollen - if they have not, then carefully make a nick in the seedcoat (being careful not to damage the embryo) and soak for a further 12 hours before sowing[
