What is the harvest period for rosemary?

The harvest period for rosemary typically occurs in late spring to early summer when the plant is in full bloom and the leaves are at their most aromatic. You can also harvest rosemary throughout the growing season, as needed, but it is best to avoid cutting too much during the winter months when the plant is dormant. For optimal flavor, it's recommended to harvest in the morning after the dew has dried but before the heat of the day sets in.
