Before you grab your pruners, read on to discover the how-tos and why-fors of pruning. Is now a good time? Are you too early? Are you too late? Well, you need to have a little information before you know the answers to those questions… That’s because some flowering shrubs bloom on old wood, which means last season’s growth. So if you prune one of those shrubs, you’ve lost your bloom for the season. Examples are smooth hydrangeas, lilacs, forsythia, azaleas, and rhododendrons. Others, such as limelight hydrangeas (or Hydrangea paniculata), bloom on new wood and are okay to prune before blooming. Timing is everything.
Hydrangea paniculata blooms on new wood, so pruning in late winter / early spring means you’ll still get blooms in summer.
The First Rule of Pruning? Know Thy Plant.
Late winter to early spring is prime time for pruning, but what does “late winter” even mean? Think of it as that in-between time when winter is loosening its grip, but spring hasn’t entirely sprung. The best pruning happens before new growth begins, so wounds heal more quickly. In Western North Carolina, that’s late February to early March.
Prune before buds swell, but not so early that your plants suffer winter injury. (Yes, plants can get frostbite, too.)

Why do you want to prune out “water sprouts” or suckers? They compete for resources, potentially leading to weaker growth and reduced bloom or fruit production, and they can disrupt your plant’s shape and structure.
Never Prune Without a Reason
Some shrubs need regular pruning; others prefer to be left alone. Ask yourself: Why am I pruning?
- The Jungle Effect: Your plants are swallowing your house, driveway, and possibly the dog. It’s time to regain control.
- Rejuvenation Pruning – Old shrubs like rhododendrons, azaleas, and butterfly bushes need a fresh start. Drastic cuts (down to six inches) can bring them back to life.
- Tidy Up – Remove suckers, wild shoots, and old wood for a polished look.
- Better Blooms, More Fruit – Redirecting energy into flowering and fruiting instead of excess growth.
Most homeowners dread the formal “meatball” look, but are equally terrified of letting plants grow naturally. But, we promise, it’s okay to let plants breathe a little and be a bit more natural-looking.
Every gardener needs a good reference book when it comes to pruning. Here’s a favorite of one of our garden gurus: The Pruning Book: Completely Revised and Updated by Lee Reich
How to Prune Like a Pro
✅ Cut out all diseased, damaged, or dead wood—a year-round chore.
✅ Thin out crowded, dense limbs to improve air circulation.
✅ Remove suckers and water sprouts (those fast-growing, energy-stealing shoots).
✅ Get rid of crossing branches before they start rubbing and causing damage.
✅ For fruiting plants, cut back at least six inches into healthy wood to encourage better harvests.
Types of Pruning (And Why They Matter)
✂️ Rejuvenation – A big reset for old shrubs like red twig dogwood.
✂️ Shearing – Hedges need a careful trim to let light in and stay healthy.
✂️ Heading Back – Encourages bushy growth and more flowers.
✂️ Thinning – Opens up the plant, letting in more air and light.
Most plants benefit from thinning and heading, but the golden rule? Never remove more than one-third of the plant at once. On the other hand, fruit trees and berry bushes need severe pruning for serious harvests. Don’t be shy!
