Pruning stiff goldenrod — FAQ
When should I prune stiff goldenrod?
Late winter for cutback; deadhead post-flowering in autumn to limit reseeding. Cut all old stems to ground level in late winter before new basal growth begins. Remove spent flowerheads in autumn if self-seeding is unwanted. Pinch stem tips by one-third in late May only if the site is very exposed and height control is needed.
How often does stiff goldenrod need pruning?
Annually (late-winter cutback); deadheading optional in autumn. Stiff Goldenrod is a well-behaved, clump-forming native that spreads more slowly than some goldenrods. Deadhead after flowering if you want to limit self-seeding, or leave the seed heads for overwintering birds. Cut stems back to ground level in late winter. A late-spring tip pinch can reduce height in very exposed spots.
