Acacias can suffer from a number of pests, including borers, scale, galls and leaf miners. Growing plants suitable to your local environment minimises these occurring.
Propagation is easy from scarified seed by covering with boiling water for 24 hours and discarding any seeds still floating on the surface.
Similar to Acacia cheelii and A. blakei.
Most wattles regenerate from seed after fire with some species exhibiting reshooting/suckering from bases of trunks.
