How Often Should You Prune Shrubs?

Resources: Tree Trimming

Our arborists recommend pruning shrubs every year in order to keep them healthy and aesthetically appealing.

Why Should You Prune Shrubs?

The short term effects of not trimming your shrubs are that they will be bushy, larger, and look messy. However; the cause for concern comes with the long term effects of not pruning shrubs. In the long term, the interior branches of you plant will become so dense that they stop getting sunlight or nutrients. Essentially, the bush becomes too big to support itself. In response the shrub begins to decay and the wood becomes unproductive which means less flower production thus lowering the overall appeal of your landscape.

 On the other hand pruning shrubs:

  • creates fresh growth
  • promotes flowers production
  • creates an overall stronger more resilient shrub     

When Should You Prune?

The best time for pruning shrubs varies by species. When deciding when to prune your shrubs take into account if they are flowering plants, and when they flower. As a rule of thumb if you are doing major pruning, it’s best to cut back the shrub during the dormant season (winter).

Bushes That Don’t Flower

Plants that do not flower can be pruned at any time except late autumn. Bushes trimmed in late fall may not have enough time to harden off the pruning cuts before the first frost. This could cause damage to the bush. Popular bushes without blooms include burning bush, boxwoods, and barberry.

Summer Flowering Plants – Prune In Late Winter to Early Spring

Plants that flower in the summer grow their flowers on the new growth developed in spring. To promote flower growth it is best to prune these plants in late winter or early spring. Pruning at this time will also allow you to easily see the plant’s structure because of the bare branches and the upcoming spring growth will quickly heal wounds. See the list of common summer flowering shrubs below.

  • Beautyberry (Callicarpa species)
  • Bumald spiraea (Spiraea bumalda)
  • Butterfly bush (Buddleia davidii)
  • Gardenia (Gardenia jasminoides)
  • Japanese barberry (Berberis thunbergii)
  • Japanese spiraea (Spiraea japonica)
  • Nandina (Nandina domestica)
  • Privet (Ligistrum species)
  • Repeat-flowering roses (Rosa species)
  • Rose-of-Sharon (Hibiscus syriacus)
  • Summersweet (Clethra species)
  • Sweetshrub (Calycanthus floridus)
  • Hydrangeas

Spring Flowering Plants – Prune In Late Spring to Early Summer

Plants that flower in spring grow their flowers on the growth from the previous year. Pruning in late spring to early summer, immediately after their blossoms fade, will increase flower production for the following year. If you wait to prune these types of bushes during summer or winter you will see lower amounts of spring bloom. See the list of common spring flowering shrubs below.

  • Azalea (Rhododendron species)
  • Beautybush (Kolkwitzia amabilis)
  • Bigleaf hydrangea (Hydrangea macrophylla)
  • Bridal wreath spiraea (Spiraea prunifolia)
  • Common lilac (Syringa vulgaris)
  • Deutzia (Deutzia species)
  • Flowering quince (Chaenomeles species)
  • Forsythia (Forsythia species)
  • Japanese kerria (Kerria japonica)
  • Japanese pieris (Pieris japonica)
  • Mock orange (Philadelphus species)
  • Rhododendron (Rhododendron species)
  • Weigela (Weigela florida)

Can I Prune My Shrubs Myself?

We do not recommend trying to prune your shrubs yourself. Pruning shrubs is a skill that takes training. First you need to determine what type of pruning needs to be done; then you must have the knowledge of proper pruning cuts to successfully prune your shrubs in a non-harmful manner. Like trees, improper pruning cuts on bushes can lead to disease and decay. Even worse, if you choose to shear your bushes you are risking shearing injuries that can cause your shrubs to die prematurely. (See more about shearing below) Because the cost of removing and replacing shrubs that die from improper pruning can be costly, it’s much easier and more cost effective to trust a qualified company to do the pruning for you.

Types of Shrub Pruning:

Renewal Pruning: This type of shrub pruning involves removing ¼ to 1/3 of the oldest stems at the base of the shrub. This keeps the interior branches from overcrowding and allows sunlight to reach the base of the plant, which stimulates growth.

Selective pruning: This pruning maintains a shrubs natural form through selective thinning and reduction.

Shearing (BAD TECHNIQUE): Shearing is a detrimental practice that is unfortunately very common. When homeowners or landscapers shear plants they are making cuts indiscriminately without regard to the location of the plant’s natural protection zones. These improper cuts cause the death of healthy shoots and become an entry point for diseases. Shearing is also not very effective. Shearing removes only the upper and exterior portions of a shrub. This leaves the dead, dying, and over-mature branches that are most commonly located in the interior of the shrub.

We have been using RTEC for years and were very pleased with the recent tree maintenance work they did for us. As always, we got good advice from their arborist Ben,. The crew that did the work is highly skilled, and they did a great job trimming our trees. They worked safely and efficiently, in addition to leaving the yard clean after they finished the work.

RTEC was at my house today to removed a large Magnolia that was badly damaged by the recent snow. They did a fantastic job at a very reasonable price. They arrived right on time, worked efficiently and quickly and cleaned up so well it was hard to tell anything have been disturbed. Over the past several years, I have used RTEC for all the services I checked above, and have always been very pleased with their service and professionalism. I also appreciate that they are not eager to take down trees that don't need to come down. In this case, the damage was too extensive for the tree to recover.

Once again, RTEC has done a great job. The team showed up right on time and performed all the work that we agreed to. They kept us informed as to progress, coordinated with us concerning our maple, and made recommendations concerning ongoing support for our trees. At the end of the day, they thoroughly cleaned up the debris and left our yard in pristine condition. WELL DONE.

Not our first time but this time was tricky removal of a large dead tree leaning on a healthy tree. Quick response for estimate, good timing to removal, all clear and healthy tree still fine.

We’ve used RTEC for many years for tree maintenance and can’t say enough good things about their service. We use them for tree trimming and for regular treatments to maintain our trees’ health and deal with pests and prevent disease. Their arborist Ben has been especially helpful with advice. RTEC also been especially helpful in emergency situations, once coming to cable a massive, heritage oak in our yard right before a hurricane was about to hit. Highly recommend.

RTEC did an excellent job onsite of removing dead branches from our 80+ year old trees, and trimming other growth too close to our home.
