Should I cut back this butterfly bush?
I bought this little plant last fall at a local Kroger and it bloomed for a while and eventually dropped a lot of its leaves and then there was new growth. Almost everything you see on this plant at this point was growth from last fall.
I have read that it is best to cut them back in the spring to promote new growth. I have read some sites that say you can cut it back to the ground and other that say to about 10"
I am not sure if you can tell from the bad photo but the longest branches on this plant are only about 12-15" long at this point. Should I still cut it back and if so, how should I go about it?
Any advise on how to care it would be appreciated. I did give it a general purpose fertilizer today.
