To trim liatris, wait until the flowering period is over, typically in late summer or early fall. Use clean, sharp pruning shears to cut back the spent flower stalks to the ground, removing any dead or damaged leaves as well. This will help promote healthy growth for the next season and maintain a tidy appearance in your garden. Avoid cutting back the foliage too early, as it can provide winter interest and protection for the plant.
