What's the best way to keep a new butterfly bush watered? Thanks for your help.
Baltimore County Maryland
If there is no rain, check the plant at least once a week and water it thoroughly for several minutes so that the water soaks in deeply.

Butterfly bushes are very adaptable, so much so that they are now invasive in natural areas of Maryland. We recommend cutting back the spent blooms after it flowers, to help avoid re-seeding.
Thank you very much for your help. It means a lot.
