I know that conventional wisdom holds buddleia should be pruned back hard every year to encourage bloom. But….some volunteers have grown into an informal hedge–they are 8+ feet now and form a rather nice garden wall. Does anyone have experience with not pruning buddleia back? Will I get only a few blooms? Instead of pruning the entire bush back, I’m thinking of removing the thickest/oldest canes to make way for new growth.
