One method to keep Smokebush (Cotinus coggygria) small is by cutting it back hard to the ground. This technique, known as hard pruning, can help promote new growth and keep the plant compact and manageable in size. By cutting the plant back to the ground, you stimulate the growth of new vertical shoots that often have larger leaves and more vibrant foliage coloration.
I have personally used this technique with Smokebush in my own garden, and it has been quite successful in keeping the plant at a desired size. When the plant starts to become too large or unruly, I prune it back hard in early spring before new growth begins. I use sharp pruning shears or loppers to cut the stems close to the ground, removing all the old woody growth.
After the hard pruning, it’s important to provide the plant with adequate care to support its vigorous regrowth. This includes regular watering, especially during dry periods, and fertilizing with a balanced fertilizer to provide the necessary nutrients for healthy growth. Mulching around the base of the plant can also help retain moisture and suppress weed growth.
One of the advantages of hard pruning Smokebush is that it rejuvenates the plant and encourages the development of fresh, vibrant foliage. The new growth often has larger leaves and can showcase the plant’s characteristic deep purple or burgundy coloration, adding visual interest to the garden.
It’s worth noting that hard pruning should be done with caution, as it may temporarily reduce or eliminate flowering for a season or two. Smokebush is known for its attractive feathery flower clusters, so if you value the blooms, you may want to consider alternative pruning methods, such as selective pruning or light shaping, to maintain a balance between size control and floral display.
Hard pruning can be an effective technique for keeping Smokebush small and compact. By cutting the plant back to the ground, you can encourage new growth with larger leaves and enhanced foliage coloration, adding beauty and interest to your garden.
