Propagation
The hard coated seeds require scarification by placing them in hot water (90° C) for one minute or submerged in sulphuric acid 30 minutes. Alternatively mechanical scarification can be applied.
Sow the seeds in a well drained media and maintain a temperature between 20 to 30°C (68º-.86º F) Germination occurs within 10 days and when large enough to handle prick-out and pot up.
Note:
General information on pruning Acacia species
Tolerates a light prune after flowering back to a node, remove any dead wood back to the collar. If there is insufficient light towards the base of the tree prune the crown to allow the light in. The plants tend to be easily damaged by wind or borers, and damaged material should be removed.
