Pruning your artichokes In areas where artichokes are grown as a
perennial plant, they are pruned back several times a year to
stimulate new shoots for year-round cropping. They can be cut
back from mid-April to mid-June for cropping in the fall,
winter, or spring. If they are cut back in late August or
September, they will produce a summer harvest. Annual crops are
not cut back at any time except after harvest.
