When watering your Black Knight Butterfly Bush, be sure to give it a good soaking, as this plant doesn’t like to be kept too wet. Once every two weeks should be sufficient in most cases. If you live in an area with particularly hot, dry summers, you may need to water more often.

If you notice that your plant is starting to drop its leaves or look wilted, it’s a tell-tale sign that it needs more water. Don’t let your plant go completely dry, as this can cause irreversible damage.

By following these simple watering tips, you can keep your Black Knight Butterfly Bush healthy and looking its best, even during periods of drought.
