Evergreen perennials are often fast growing and require periodic pruning to renew them and keep them vigorous. With all the warm weather he had in January things have already started growing and it’s important to remove old growth to make room for new blooms and foliage. Perennials such as penstemon and Santa Barbara daisy benefit from a hard shearing this time of year. I often use a special Japanese serrated knife to speed up this chore. This tool is called a root knife, and is available at leevalley.com , which carries many hard to find gardening tools and accessories. With the root knife you can grab all of the foliage of a plant like catmint with your left hand, and slice off all of the old growth with your right. The new shoots that remain quickly produce new blooms and the plant looks 100% better. Once the danger of hard frost has passed, it will be time to cut back frost tender evergreen shrubs such as fuscias and loropetalums (Chinese fringe flower).
