|WHAT KIND OF FERTILIZER AM I SUPPOSED TO USE ON BUTTERFLY BUSHES?|
I apologize for this delayed reply to your gardening question and hope it is still helpful to you.
There is no particular type of fertilizer for butterfly bushes. I find that regular lawn fertilizer works just fine. Sprinkle a half cup evenly throughout a 6 foot diameter area around each bush and then water it in well.
Thanks for the question. Best wishes for a wonderful gardening season. Please stop in again soon!
