Answer: Smoke bush typically develops leaves only on the new growth so to keep yours full and thick you'll need to prune it back to promote lots of new growth on all of the branches. The center of the plant will eventually become bare but as you prune, you'll encourage lots of new growth at the tips of the stems and this new growth will hide the bare centers of the plants. Prune it back now to promote new growth and remember to prune it every spring, just as new growth begins. Enjoy your garden!
