How to Grow

Soil: Butterfly bushes require very well-drained, even dry, soils. Do not amend or add anything to the soil at planting time, as this can cause serious drainage problems. In clay soil, plant butterfly bush so they are slightly above the soil.
Light: Sun (> 6 hours sun).
Water: Low to average watering; soil can even be dry once established. Butterfly bush does not tolerate wet conditions for any period.
Spacing: 3-6 feet
Fertilizing: Little needed; if desired, apply a granular rose or garden fertilizer in early spring.
Winterizing: In fall, plants can be trimmed lightly, but save major pruning for spring. Do not fertilize in fall, and if mulching, do not apply heavily at the base of the plant.
Maintenance & pruning: Butterfly bushes are best pruned in spring, once the new growth has emerged. At that point, cut just above where big, healthy buds appear. Give butterfly bushes plenty of time to emerge in spring, especially in colder climates - this may take several weeks, even if other plants in your yard are already leafing out.

Plant spacing is based on the ultimate width of the plants. This figure is normally given as a range; for example, 3-5’. If you live in a cold climate and/or want plants to fill in more quickly, plan to space at the shorter end of the range. If you live in a warm climate, are on a limited budget, or are willing to wait longer for plants to touch, use the higher end of the range. Using the larger number is recommended when calculating distance from a building or structure. There’s really no such thing as "maximum spacing": if you don’t want your plants to touch, you can space them as far apart as you’d like. All plant spacing is calculated on center, or in other words, the centers of the plants are spaced one half of their eventual width apart:

bush distance

Unless you are planting in a straight line, as you might for hedges or edging, space your plants in a staggered or zig-zag pattern for a more interesting and naturalistic look:

How does it grow in clay or acidic soil??

Great Garden Plants

Hello! If you have clay soil, you'll want to plant butterfly bush so they are slightly above the soil. This will help with proper drainage. If you have acidic soil, it might still be suitable for a butterfly bush as long as the soil is well-drained and not prone to staying wet for long periods. Just remember not to amend or add anything to the soil at planting time to avoid causing serious drainage problems, especially if you have clay soil.
