How to Care for Your Butterfly Bush
Light Requirements
Butterfly bushes thrive in full sun, so be sure to plant them in a location that receives at least six hours of direct sunlight per day.
Soil Requirements
Butterfly bushes prefer well-draining soil that's slightly acidic (pH 6.0 to 7.0). If your soil is heavy clay, amend it with compost or sand to improve drainage.
Watering
While butterfly bushes are drought-tolerant once established, they still need regular watering during their first year of growth. Water deeply once a week, and be sure to mulch around the base of the plant to help retain moisture.
Pruning
To encourage bushier growth and more blooms, prune your butterfly bush in early spring before new growth appears. Cut back the previous year's growth by half, making cuts just above a set of healthy buds.
