Prune: Remove excess and crossing branches to reduce wind resistance. Remove small trees that
sucker from the roots. This tree responds well to pruning.
Litter: Seed pods.
Propagation: Scarified seed. This plant depends on animals, including cattle, to disperse its seeds.
Acacia salicina is a member of the Legume family (Fabaceae). It is very hardy and adaptable when
the soil is well-drained. Its disadvantages are branch breakage in strong winds and frequent suckering.
