Answer: Buddleia can be trimmed or even cut back heavily to promote new growth and rebloom. To trim it, simply cut bloom stalks back about 6" to 12" below the base of the bloom. For heavier trimming cut the bush back by 1/3 to 1/2. This will help maintain this vigorous shrub at a smaller size and will result in lots of vigorous new shoots and blooms.
