Black wattle is a hardy, fast-growing tree that thrives in full sun to part shade and tolerates a wide range of soil types. Water regularly during establishment but reduce frequency once the tree is mature, as it becomes moderately drought tolerant. Prune lightly after flowering to maintain shape and prevent it from spreading beyond your desired area.
