Hi Sunshine! I got my Butterfly bush last summer and had to wait until it cooled down to
plant it in the ground. The lady at the nursery told me to snip off the spent blooms to insure more growth through the
growing season and just as the other reply said leave it alone until the next
spring.As the new growth comes on just trim off the brown dead branches but if you see even a bit of green leave it alone.There might be life coming off of the brown dead looking spots. Trim down to that point but no further. I LOVE
my Butterfly
plant and so have the butterflies this year. Good Luck and Happy Gardening!
