How Far Back Can You Trim Boxwoods Without Harm?
How Far Back Can You Trim Boxwoods?
Boxwoods can be trimmed back as far as one-third of their mass when pruning.
Thinning out the shrubs is a better method for reducing their size compared to shearing them into unnatural shapes.
Thinning allows sunlight to reach the center of the plant and promotes dense, leafy growth.
It is important to use sharp handheld pruning shears to selectively cut back too tall branches to a larger branch or the base of the plant.
Following the one-third rule helps maintain the health of the boxwood.
Additionally, clean pruning tools before and after pruning to prevent the spread of boxwood blight, a deadly fungal disease.

Did You Know?
1. Boxwoods, which are commonly used for hedges and topiaries, have been cultivated for thousands of years, dating back to ancient Egypt and Greece.
2. The practice of trimming boxwoods is known as “shearing” and can be traced back to Renaissance gardens in 16th-century Europe, where elaborate patterns and shapes were created.
3. Boxwoods are one of the few shrubs that can tolerate heavy pruning and can be trimmed back to bare branches if necessary. They have a remarkable ability to regenerate and bounce back from drastic cuts.
4. In Japan, the art of shaping and trimming boxwoods is known as “Karikomi” and is an essential element of traditional Japanese gardens.
5. Boxwoods are slow-growing evergreen shrubs, and their growth rate can vary depending on the variety and environmental conditions. While some may only grow a few inches per year, others can grow up to a foot per year.
The Best Tool For Pruning Boxwood
Pruning boxwood shrubs can be a challenging task due to their slow growth and evergreen foliage. However, with the right tools and techniques, it can be a rewarding and effective practice. Sharp handheld pruning shears are the best tool for this job as they allow for precise and clean cuts, minimizing the risk of damaging the shrub.
When selecting pruning shears, look for a pair with sharp bypass blades that can make clean cuts without crushing the branches. It is important to avoid using anvil-type shears as they can crush the stems, leading to damage and potential disease. Additionally, sanitize the shears before each use to prevent the spread of any pathogens that may be present.
To summarize:
- Pruning boxwood shrubs requires the right tools and techniques.
- Use sharp handheld pruning shears for precise and clean cuts.
- Avoid anvil-type shears to prevent damage and disease.
- Sanitize the shears before each use to prevent the spread of pathogens.

Timing For Pruning Boxwood
The timing for pruning boxwood plays a crucial role in its overall health and growth. Pruning in spring, before new growth emerges, is generally recommended. This encourages vigorous new growth, giving the shrub a fresh and rejuvenated appearance. However, it is important to avoid pruning boxwood in late summer or fall, as this can damage the shrub during the harsh winter months.
Late summer and fall pruning can result in the shrub being more susceptible to winter injury and may cause significant damage to the foliage. It is best to allow the shrub to go into winter with its natural growth intact, providing protection against freezing temperatures and harsh weather conditions. By timing the pruning properly, you can ensure the long-term health and vitality of your boxwood shrubs.
Pruning Dead, Damaged, Or Diseased Branches
When it comes to dead, damaged, or diseased branches on your boxwood shrubs, prompt pruning is essential. Identifying and removing these branches as soon as they are noticed will prevent further damage to the plant and allow it to allocate its resources towards healthy growth.
To prune dead or damaged branches, use your sharp handheld pruning shears to make clean cuts close to the base of the shrub or to a larger branch. This will prevent any stubs that could potentially become entry points for diseases or pests. Regularly inspect your boxwood shrubs for any signs of disease or damage, and take immediate action to maintain the overall health and appearance of the plant.
The Dangers Of Shearing Boxwood
While shearing boxwood may seem like a convenient way to maintain its shape and size, it can actually have detrimental effects on the shrub’s health and appearance.
Shearing involves cutting the outermost layer of growth, resulting in a shell of green foliage with bare branches within the interior. This not only disrupts the natural form and growth pattern of the boxwood but also makes it susceptible to pests and diseases.
Additionally, shearing boxwood into unnatural shapes weakens the shrub’s structure and restricts its ability to grow and thrive.
The dense and tightly packed growth that shearing creates does not allow for proper air circulation and sunlight penetration, making the inner branches more prone to disease and pest infestations.

- Sheared boxwood is more susceptible to pests and diseases.
- Boxwood sheared into unnatural shapes weakens the shrub’s structure.
- It restricts the shrub’s ability to grow and thrive.
- The tightly packed growth from shearing limits air circulation and sunlight penetration.
- Inner branches become more prone to disease and pests.
The Benefits Of Thinning Out Boxwood Shrubs
Thinning out boxwood shrubs is a superior alternative to shearing when it comes to maintaining their size and shape. Thinning involves selectively removing taller branches to allow sunlight to reach the center of the plant and promote dense, leafy growth. This method preserves the natural form and structure of the shrub and ensures better airflow, reducing the risk of diseases and pests.
To thin out a boxwood shrub, use handheld pruning shears to carefully cut back taller branches to a larger branch or even to the base of the plant. This selective pruning approach encourages healthy growth and prevents the formation of dense, unnatural shapes. Remember to follow the one-third rule, which advises against removing more than one-third of the shrub’s mass at a time to prevent stress and maintain its overall health.
For significantly overgrown boxwood shrubs, phased pruning may be necessary. This involves removing one-third of the shrub’s mass each year until the desired size is reached. Gradually reducing the size allows you to avoid harming the shrub and ensure its long-term vitality.
pruning boxwood shrubs can be a careful and deliberate task. Using sharp handheld pruning shears and timing the pruning correctly are vital for overall health and growth. Pruning dead, damaged, or diseased branches promptly is crucial, while avoiding the dangers of shearing and opting for thinning out the shrubs instead ensures their natural beauty and resilience. With these considerations in mind, you can confidently trim boxwoods without harm, maintaining their health and enhancing their aesthetic appeal in your garden.

Frequently Asked Questions
Can boxwoods be cut way back?
Yes, boxwoods can be pruned back significantly and they will regrow beautifully. Unlike other evergreens such as firs, pines, and spruce with “whorled branches,” boxwoods have the unique ability to sprout new growth even from areas that have been cut back to leafless wood. This makes them a versatile and resilient choice for landscaping, as they can be easily shaped and maintained without compromising their overall health and structure.
How do you reduce the size of a boxwood tree?
To successfully reduce the size of a boxwood tree, a careful approach is required. Begin by utilizing loppers or shears to significantly reduce the plant’s overall size, leaving at least half to two-thirds of the foliage intact. By preserving this foliage, the tree can continue to generate the necessary energy for recovery. Over time, new foliage should emerge along the bare stems, although it may take several seasons for the plant to fully regain its former state.
How much can you cut down a boxwood?
Boxwood shrubs should be pruned with caution, as removing more than 1/4 of the shrub in a single season can be detrimental to its health. However, if you have a boxwood hedge that requires grooming, it is advisable to shear them in early June for optimal results. For other pruning needs, it is best to undertake the task in March, during early spring when the shrub is settling into the growing season.
Can you trim boxwoods all the way down?
When it comes to trimming boxwoods, caution is advised to avoid damaging the plant. Due to their sensitivity to hard pruning, it is recommended to take a more gradual approach. Over two years, you can reduce the size of an overgrown boxwood by cutting back its branches by half their length in the first year and then repeating the process the following year until the desired length is achieved. This method allows the boxwood to adjust gradually and ensures a healthier pruning outcome.
