Q: My butterfly bushes have been blooming wonderfully! Is there anything I can do to make them keep putting out the large flowers?

A: Butterfly bush produces blooms on new stems. This means that unless new growth is constantly being formed, flower production will decrease. Hang an old pair of scissors on a stick near the bush and use them to clip off faded flowers whenever you pass by. Every three weeks from now on, shorten a few branches by two feet so they will put out new growth.
