Renewal pruning involves removing old, unproductive, or damaged branches from shrubs or trees to stimulate new growth. It is typically used on older plants that have become overgrown or have stopped producing healthy foliage or flowers. This pruning technique rejuvenates the plant by encouraging vigorous new growth from the base or from healthier sections of the plant. Renewal pruning can be done gradually over several years or in one more extensive session, depending on the plant�s condition.
