Answer: You can prune your plant back, but it isn't necessary, unless you want to control its size or reduce the leggyness it can develop with age. How much you prune depends upon how large it is. It takes well to hard pruning in late winter or early spring. Pruning down to a few inches above the soil line will renovate your plant. If it is not overgrown and you simply want to control the shape rather than the size, you can safely prune off about one-third all the way around. This will result in dense, compact growth. Best wishes with your garden!
