Pruning Broom and Butterfly Bush: Timing and Technique

Different Approaches for Two Shrubs

Broom (Cytisus): Prune only dead/dying branches back to main stems. Light shaping only—avoid severe cuts.

Butterfly Bush (Buddleia): Can be cut to 5-6 inches above ground anytime before first frost. This hard pruning promotes vigorous spring growth and abundant blooms.

Key Difference

Broom blooms on old wood—minimal pruning. Butterfly bush blooms on new wood—hard pruning beneficial.
