How to Prune Overgrown Garden Shrubs

Shrubs that have been left to their own devices eventually become leggy, woody, and unproductive. When a plant stops putting energy into foliage and instead creates thick, tangled thickets of dead branches, it is time to intervene. A well-pruned shrub looks balanced, allows light to reach the interior leaves, and responds with fresh, vigorous growth in the coming season. Done well, pruning is a systematic process of selective removal rather than a crude haircut. Avoid the temptation to shear the entire plant into a perfect ball, as this creates a dense outer shell that chokes out the center. Instead, focus on opening the plant up and bringing it back to a manageable size, ensuring that the final shape mimics the plant's natural growth habit.

  1. Clear the Base First. Start by removing any weeds, grass, or debris from around the base of the shrub. Clear a clean perimeter to give yourself room to maneuver and access the lowest branches safely.
  2. Remove Dead Wood Now. Identify and cut away all dead, damaged, or diseased wood first. Make your cuts flush against the main branch or trunk without cutting into the branch collar.
  3. Stop Branch Rubbing. Look for branches that rub against each other, as these cause wounds that invite pests and disease. Remove the weaker of the two to stop the friction.
  4. Open Up the Center. Thin out the interior of the shrub by removing stems that grow inward toward the center. This encourages airflow and lets sunlight penetrate the heart of the plant.
  5. Cut Leggy Branches Back. Shorten long, leggy branches by cutting back to a lateral bud or a junction point. Do not remove more than one-third of the total foliage in a single season.
  6. Sanitize Your Tools. Gather all clippings and rake the surrounding soil thoroughly. Wipe your blades with rubbing alcohol to prevent spreading pathogens to other plants in your garden.
