Harvesting Artichoke
The Globe artichoke is actually an edible bud. It is harvested at an immature stage and selected for size and compactness. Overdeveloped Globe artichoke buds begin to open or spread; the bracts may have a brownish cast and are tough and stringy; the artichoke hearts have a fuzzy, pink to purple appearance.
As a perennial: For artichokes planted in the fall, harvest can begin as early as spring. Maturation and harvest will continue through the following spring unless interrupted by frost. Peak production occurs in spring.
As an annual: For artichokes planted in the spring, harvest in the fall.
Handle buds carefully during harvest to avoid bruising bud leaves. To harvest artichokes, cut the bud from the stem about 1" - 1½" inches below the bud base. Buds allowed to become over mature will be loose, fibrous and inedible. Artichoke blossoms, however, are attractive as fresh or dried flowers.
After harvest, cut back old bearing stalks to ground level and mulch with rotted manure, or feed with a balanced fertilizer. New shoots, which grow from the base of the old stump, will develop their own stalks. Monthly applications of nitrogen fertilizer are beneficial for healthy growth.
