Pruning and caring for red valerian
Red valerian is definitely an extremely easy plant that requires no care at all. You can cut off wilted flowers when they die off if you wish, but this is only aimed at making it look nicer and won't influence plant behavior. Cut back short in fall, once the leaves have wilted.
Should I cut back valerian after flowering?
Plant valerian in an informal setting in moisture-retentive soil. After flowering in summer, cut back faded flower stems to avoid self seeding, then cut back all growth after it has died back in autumn. Propagate by seed, division, or cuttings.
