: ...also if you haven't already fertilized the butterfly bush, use an all purpose fertilizer, or in particular a "bloom booster" that promotes budding and new growth even more. But again, the butterfly bush usually doesn't have problems with blooming if the plant is in full sun.
If you have added organic matter in the form of compost and have mulched, you shouldn't have to fertilize. If you do feel the need, you could use something organic that doesn't leave behind residual salts such as sea kelp or fish emulsion.
