Enhancing the Appearance of Your Landscape

Ornamental shrubs play a vital role in creating a visually appealing landscape. Pruning and shaping these shrubs can help you achieve the desired aesthetic effect. By removing overgrown branches or stems, you can bring out the natural shape and beauty of the shrubs. Additionally, strategic pruning can create attractive focal points, define borders, or enhance the overall symmetry of your garden.

Promoting Health and Growth

Pruning also promotes the overall health and growth of the shrubs. By removing dead, damaged, or diseased branches, you prevent the spread of diseases and pests. Pruning stimulates new growth and allows more sunlight and air circulation to reach the inner parts of the shrub, promoting better health. It also helps in removing weak or crossing branches, allowing stronger ones to thrive and reducing the risk of breakage.

Controlling Size and Shape

One of the primary reasons for pruning ornamental shrubs is to control their size and shape. Regular pruning prevents shrubs from becoming too tall or wide, maintaining them at a desirable size that fits your landscape. By selectively pruning certain branches, you can shape the shrubs into a specific form or encourage branching in a desired direction. Controlling the size and shape of shrubs helps in preventing overcrowding and allows other plants in your landscape to receive adequate light and nutrients.

Improving Flowering and Fruiting

Pruning at the right time and in the correct manner can significantly improve the flowering and fruiting of your ornamental shrubs. By selectively removing spent flowers, you encourage the shrubs to produce more flowers, enhancing their overall beauty. Pruning can also help in removing excess branches or stems that may hinder the growth or development of fruit. It allows the shrub to focus its energy on producing larger and healthier fruits, boosting not only their visual appeal but also their taste.

Best Time to Prune Ornamental Shrubs

To ensure the best results when pruning your ornamental shrubs, it is crucial to know the best time to prune. The timing varies depending on the type of shrub and its flowering season.

Deciduous Shrubs

Deciduous shrubs, which shed their leaves in the fall or winter, are typically pruned during dormancy. Late winter or early spring, before new growth begins, is an ideal time to prune deciduous shrubs. This allows the shrub to allocate maximum energy to new growth and minimizes the risk of damage from extreme cold temperatures.

Evergreen Shrubs

Evergreen shrubs, which retain their leaves year-round, can be pruned throughout the year. However, it is generally recommended to avoid pruning during extreme heat or cold. Pruning in early spring or late winter, just before new growth emerges, is a good option for most evergreen shrubs.

Flowering Shrubs

Flowering shrubs can be divided into two categories based on their blooming season: spring-flowering shrubs and summer-flowering shrubs. The timing of pruning these shrubs differs, as it directly affects the formation of flower buds.

Spring-Flowering Shrubs

Spring-flowering shrubs, such as lilacs and forsythia, produce blooms on old wood. Therefore, they should be pruned immediately after flowering. Pruning them in late summer or fall may result in the removal of the buds for the following year’s blooms.

Summer-Flowering Shrubs

Summer-flowering shrubs, like hydrangeas and butterfly bushes, bloom on new wood. They can be pruned during late winter or early spring before new growth emerges. Pruning them at this time helps promote new growth and encourages abundant flowering during the summer.

Pruning Newly Planted Shrubs

If you have recently planted shrubs, it is essential to allow them to establish their root systems before pruning. Generally, it is recommended to wait at least one full growing season before pruning newly planted shrubs. This allows the shrubs to develop a strong foundation and encourages healthy growth for the years to come.

Tools Required for Pruning

To effectively prune and shape your ornamental shrubs, you will need a set of appropriate tools. Having the right tools not only ensures clean and precise cuts but also makes the pruning process easier and safer. Here are some essential tools for pruning:

Pruning Shears

Pruning shears, also known as hand pruners or secateurs, are essential for cutting small branches and stems. They are ideal for precision pruning and can handle branches up to ¾ inch thick. Look for pruning shears with a bypass cutting mechanism, as they provide a cleaner cut and reduce the risk of damage to the plant.


Loppers are similar to pruning shears but have long handles, allowing you to reach and cut thicker branches. They are suitable for branches up to 2 inches in diameter. Choose loppers with sharp blades and ergonomic handles for comfortable and efficient pruning.

Hedge Shears

Hedge shears are designed specifically for shaping and trimming hedges and dense shrubs. They have longer blades and handle larger amounts of foliage. Select hedge shears with sturdy blades and cushioned grips to reduce hand fatigue during pruning.

Pruning Saw

Pruning saws are useful for cutting thicker branches that cannot be handled by pruning shears or loppers. They have sharp, serrated blades that make cutting through wood easier. Look for pruning saws with ergonomic handles and safety features to ensure comfortable and safe pruning.

Pole Pruner

Pole pruners are essential for reaching high branches without the need for a ladder. They consist of a pruning saw or pruning shears attached to a long pole. When selecting a pole pruner, consider the reach, weight, and cutting mechanism to ensure efficient and safe pruning.

Protective Gear

Pruning can be a physically demanding task, so it is essential to wear appropriate protective gear. This includes gloves to protect your hands from cuts and scratches, safety glasses to shield your eyes from flying debris, and sturdy shoes to protect your feet.

How Do I Prune And Shape Ornamental Shrubs?

Basic Pruning Techniques

Before diving into the step-by-step process of pruning and shaping your ornamental shrubs, it is important to familiarize yourself with some basic pruning techniques. These techniques can be applied to different shrubs and play a crucial role in achieving the desired results. Here are some common pruning techniques:


Thinning involves selectively removing branches or stems to improve the shrub’s overall structure, light penetration, and air circulation. It helps in reducing overcrowding and promotes healthy growth. When thinning, remove branches at the base, or cut them back to a lateral branch.

Heading Back

Heading back is the process of cutting back branches to a certain point to encourage new growth and branching. It is commonly used to shape shrubs or rejuvenate overgrown or leggy plants. When heading back, make clean cuts just above a bud or lateral branch.


Pinching is a technique used to control the size and shape of shrubs. It involves removing the tips of new growth to encourage branching and denser foliage. Pinching is effective for shrubs that tend to become leggy or have long, unbranched stems.

Renewal Pruning

Renewal pruning is a technique used for rejuvenating older or overgrown shrubs with woody stems. It involves removing a significant portion of the old growth to stimulate the growth of new, vigorous shoots. Renewal pruning is typically done in early spring before new growth begins.

Rejuvenation Pruning

Similar to renewal pruning, rejuvenation pruning aims to revitalize older or neglected shrubs. It involves cutting back the entire shrub to a height of 6-12 inches from the ground. This drastic pruning stimulates vigorous new growth and rejuvenates the shrub.

Topiary Pruning

Topiary pruning involves shaping shrubs into intricate and artistic forms, such as animals or geometric shapes. It requires precise and careful pruning techniques to maintain the desired shape. Topiary pruning is often done with the help of frames or guides.

Step-by-Step Guide to Pruning and Shaping Ornamental Shrubs

Now that you have a good understanding of the techniques and tools involved in pruning, let’s go through a step-by-step guide to help you prune and shape your ornamental shrubs successfully:

Assessing the Shrubs

Before you start pruning, take a close look at your shrubs and determine their current condition. Identify any dead, damaged, or diseased branches that need to be removed. Observe the overall shape and size of the shrub and visualize the desired shape you want to achieve.

Preparing the Tools

Make sure all your pruning tools are clean, sharp, and in good working condition. Dull or dirty tools may cause unnecessary damage to the shrub and make the pruning process more challenging. Clean the blades with a disinfectant to prevent the spread of diseases.

Removing Dead, Damaged, or Diseased Branches

Start by removing any dead, damaged, or diseased branches. Make clean cuts just above a healthy bud or lateral branch. If the branch is too large, use a pruning saw or loppers to remove it. Be cautious not to damage the surrounding healthy branches while cutting.

Pruning for Size and Shape

Once you have removed the dead or damaged branches, begin shaping the shrub according to your desired size and shape. Use thinning cuts to remove overcrowded branches and improve light penetration and air circulation. Step back frequently to assess the shape and make adjustments as needed.

Pruning for Flowering and Fruiting

If your shrub is known for its flowers or fruits, consider the specific requirements for optimal blooming or fruiting. Remove any spent flowers or fruits to encourage the production of new ones. Refer to the recommended timing for pruning flowering shrubs to avoid removing potential buds.

Pruning Young Shrubs

Young shrubs require lighter pruning compared to established ones. Focus on removing any damaged or crossing branches to encourage a strong and balanced structure. Avoid heavy pruning that could hinder their growth and establishment.

Pruning Established Shrubs

For established shrubs, focus on maintaining their size, shape, and health. Remove any dead, damaged, or diseased branches. Thin out crowded areas and shape the shrub as desired. Be cautious not to remove more than one-third of the shrub’s growth in a single season.

Pruning Multiple-Stemmed Shrubs

Multiple-stemmed shrubs, such as certain hydrangea varieties, require special attention during pruning. Selectively remove the oldest or weakest stems at the base to encourage new growth and maintain a healthier shrub. Avoid cutting back all the stems at once to prevent stressing the plant.

Pruning Evergreen Shrubs

When pruning evergreen shrubs, focus on removing any dead or damaged branches. Shape the shrub to maintain its natural form or create a desired shape, depending on your preference. Avoid aggressive pruning as it may take longer for the shrub to recover.

Maintaining Pruned Shrubs

After pruning, remember to provide proper care and maintenance to your shrubs. Water them regularly, especially during dry periods, and apply mulch around the base to conserve moisture and control weed growth. Fertilize the shrubs as needed, following the specific requirements for each type of shrub.

Special Considerations for Specific Types of Shrubs

Different types of shrubs have specific needs and considerations when it comes to pruning. Here are some special considerations for popular types of ornamental shrubs:

Rose Shrubs

Prune roses during late winter or early spring before new growth begins. Remove any dead, damaged, or diseased canes. Thin out crowded areas and shape the shrub using heading back cuts. Hybrid tea roses benefit from more severe pruning, while shrub roses require lighter pruning.

Boxwood Shrubs

Prune boxwood shrubs in early spring or late winter before new growth emerges. Trim lightly to maintain their shape and promote dense foliage. Avoid cutting into the woody stems as they may take longer to regenerate. Keep an eye out for any signs of boxwood blight, a fungal disease, and remove affected branches promptly.

Azalea and Rhododendron Shrubs

Prune azaleas and rhododendrons immediately after flowering. Remove any spent flowers to encourage new growth. Lightly shape the shrubs using thinning cuts, avoiding heavy pruning that may affect the next year’s blooms. Avoid pruning late in the summer to allow the shrubs to set flower buds for the following year.

Juniper Shrubs

Juniper shrubs require minimal pruning. Remove any dead, damaged, or diseased branches as needed. Lightly shape the shrub to maintain its natural form or desired shape using thinning cuts. Avoid extensive pruning, as it may result in bare patches that are slow to regenerate.

Holly Shrubs

Prune holly shrubs during late winter or early spring before new growth begins. Remove any dead or diseased branches. Shape the shrub using thinning cuts, focusing on maintaining its natural form or desired shape. Be cautious while handling holly plants, as their leaves have sharp spines.

Hydrangea Shrubs

Different hydrangea varieties have different pruning requirements. For mophead and lacecap hydrangeas, prune them immediately after flowering by removing spent flowers and thinning out crowded stems. For panicle and smooth hydrangeas, prune them in late winter or early spring before new growth begins. Cut the entire shrub back to 6-12 inches from the ground to rejuvenate it.

Common Pruning Mistakes to Avoid

While pruning and shaping your ornamental shrubs, it is essential to avoid common mistakes that can hinder their growth and health. Here are some mistakes to avoid:

Heavy Pruning

Avoid heavy pruning, especially on established shrubs. Removing too much foliage can stress the plant and result in slower growth or even death. Stick to a maximum one-third rule, where you remove no more than one-third of the shrub’s growth in a single season.

Pruning at the Wrong Time

Pruning at the wrong time can result in the removal of potential flower buds or delay the blooming process. Be aware of the specific timing for pruning your shrubs and avoid pruning excessively during their blooming or bud formation period.

Improper Cutting Technique

Using improper cutting techniques can lead to damage or disease transmission. Make clean, angled cuts just above a bud or lateral branch. Avoid leaving stubs or tearing the bark, as it can create entry points for pests and diseases.

Overlooking Safety Precautions

Pruning can be hazardous if proper safety precautions are not taken. Always wear protective gear, including gloves, safety glasses, and sturdy shoes. Be cautious while using sharp tools, especially at heights, and never prune near power lines.

Ignoring Plant Specifics
