Terms of the Trade: What Is Rejuvenation Pruning?
Also known as renovation pruning, rejuvenation pruning is an extreme measure of cutting a shrub down to the ground—or a bit higher—in an effort to restart its growth process. This is commonly done when a shrub is overgrown. The remaining stems should grow back thinner and with more blooms or leaves. Rejuvenation pruning should only be done to multi-stemmed shrubs like dogwood or spirea and can take place every three to five years in the spring.
