How to prune lovage

Late autumn (cut to ground); cut flower stalks before they open to prolong leafy growth. In autumn, cut all stems to near ground level once foliage has died back. During the growing season, cut flower stalks down to a low leaf node before they fully open to redirect energy to leaves.

Full cut-back annually in autumn; flower removal as needed in summer. Lovage is a large, vigorous herbaceous perennial that dies back to the ground each winter — so 'pruning' is mostly seasonal management. Cut the whole plant down to ground level in late autumn after it dies back. Harvest stems freely through the growing season; cut back flower stalks early if you want to prolong leaf production.
