1. Butterfly bush-league need full sun. When nosotros say full sun, we mean information technology – butterfly bush crave a minimum of 8 hours of bright sunlight. Even in warm climates, institute them where they become no fewer than half-dozen hours of sun.
2. Butterfly bush need perfect drainage. Their roots are sensitive to rotting, and if they spend any amount of time in wet soil, they can be ready back or fifty-fifty die. Most of the time, if you lose a butterfly bush after wintertime, it wasn't due to low temperatures or snow or ice – it was because the institute sat in cold, wet soil in autumn or bound.
3. Butterfly bush-league can grow in dirt soil, but require a few special accommodations. Because they demand good drainage and dislike cold wet conditions, at that place are a few tips that volition increase your success with butterfly bush if you have dirt soil:

This is truthful for all shrubs, simply is even more of import with butterfly bush, as amending any soil, and specially clay soil, can crusade drainage problems.
   • Establish "high" – instead of positioning the plant even with the basis level like you lot would other plants, dig a slightly shallower pigsty (yep, that means less work!) and position it and so that the base of the institute is a bit higher than the ground. This creates a minor "hill" that encourages water to drain away from the plant rather than settle around it.

The warmer your climate, the more yous should cut dorsum your butterfly bush each spring. Even dwarf varieties like our Lo & Behold^® series still demand pruning – you lot'll just be cutting back less than you would on a variety that reaches 8' tall.

Even if everything else in your mural is turning dark-green, that doesn't mean you've lost your butterfly bush. Many people recommend waiting til as belatedly every bit Father's Twenty-four hours (the third Sunday in June) to be certain their butterfly bush-league perished. It tin can be very surprising to see how quickly a butterfly bush can recover, even if it takes that long to come up dorsum!
