Propagate from semi-hardwood cuttings in late summer for best rooting success; seed germination is slow and erratic.
Prune after flowering to maintain compact shape; rosemary does not regenerate well from old, bare wood.
Excellent companion plant for vegetables; its strong aroma deters many common garden pests.
