Light: Full sun (6+ hrs/day) to part sun (4-6 hrs/day)
Soil: Any average, well-drained soil will do.
Water: Average water needs; drought tolerant once established.
Fertilizing: Little needed; one application of a granular (not liquid) rose fertilizer in early spring is sufficient, though you may fertilize monthly from early spring through late July if desired.
Pruning: Generally speaking, you should avoid regular pruning of smokebush. You can prune selectively to develop the desired habit and shape in late winter/early spring; however, avoid cutting the plant back each year. This not only encourages a funky, unruly branching, but because smokebush blooms on old wood, it also removes developing flower buds for later that summer.
