Pruning Young Trees: Importance and How to

Pruning young trees is the selective removal of branches and stems to promote proper growth, structural integrity, and overall health.

It is important to prune young trees to eliminate broken, dead, or diseased branches, promoting proper growth. Structural pruning during a tree’s formative years aids in correcting undesirable growth patterns, and fostering proactive growth and overall health.

Ways to prune young trees involves early removal of broken or cracked branches, trimming those rubbing against adjacent branches, and identifying and eliminating codominant branches with poor attachments. Additionally, thinning and spacing branches, protecting the leader from competition, and avoiding excessive pruning height are vital practices. Regular structural pruning every 2-3 years within the first two decades of a tree’s life establishes a robust structure.

Best practices suggest managing lower branches on young trees to prevent them from becoming overly large, as leaving them aids in trunk taper development, protects the trunk from direct sunlight, and augments the tree’s strength and flexibility.

What Is Pruning Young Trees?

Pruning young trees is the horticultural practice of trimming and shaping the branches and foliage of recently planted or immature trees to encourage proper growth, structural development, and overall health.

When pruning young trees, remove broken, dead, dying, or diseased branches and conduct structural pruning to eliminate bad habits in form and promote a beneficial branch structure. 

Pruning should begin at the time of planting, and lower lateral branches should be extracted over several years to ensure good growth and prolonged structural integrity. 

What Are the Benefits of Pruning Young Trees?

Discover the advantages of pruning young trees for robust growth, improved structure, and enhanced tree health. 

1. Pruning young trees develops a strong and healthy branch structure, 
2. Stimulates new and healthy growth and promotes the overall health and appearance of the tree. 
3. By unclicking dead, dying, or damaged branches, pruning reduces the risk of disease and insect infestation, encouraging the tree to focus its energy on productive growth. 
4. Pruning young trees prevents future branch structure issues and the need for significant pruning as the tree matures.
5. Pruning controls the size and shape of young trees, preventing them from outgrowing their allotted space in the landscape or encroaching on nearby structures or utilities. This is especially important for urban or suburban environments where space is limited.
6. Pruning young trees bolsters their overall appearance by promoting a well-balanced canopy, reducing overcrowding, and correcting any irregular or misshapen growth patterns. This helps create a more attractive and visually pleasing landscape.

What Are the Common Mistakes of Pruning Young Trees?

Different species require different types of pruning, and all pruning should be minimal, eradicating what is needed. The common mistakes of pruning young trees include:

1. Over-pruning: Removing too many branches or pruning too aggressively stunts the tree’s growth and weakens its structure.
2. Improper timing: Pruning at the wrong time of year, such as during periods of active growth or extreme weather conditions, stresses the tree and makes it more susceptible to disease and damage.
3. Topping: Cutting off the tops of young trees to reduce their height leads to weak, unsightly growth and accelerates the risk of disease and pest infestations.
4. Poor technique: Using improper pruning techniques, such as leaving behind jagged cuts or pruning too close to the trunk, damages the tree and inhibits proper healing.
5. Neglecting training: Failing to train young trees to develop a strong central leader and well-spaced scaffold branches results in structural weaknesses and aesthetic issues as the tree matures.
6. Removing too many lower branches: Detaching all lower branches too early hinders trunk development and compromises the tree’s stability.
7. Ignoring the tree’s natural growth habit: Pruning young trees in a way that goes against their natural growth habit has ramifications of misshapen or unbalanced growth and detracts from their overall appearance and health.

How to Tell If a Young Tree Needs Pruning

Determining if a young tree needs pruning involves assessing its overall health, growth patterns, and structural integrity. Here are some signs that indicate a young tree requires pruning:

1. Crossing or rubbing branches: Look for branches that are crossing or rubbing against each other, as this causes damage and inhibits proper growth.
2. Dead or diseased branches: Dead or diseased branches need to be promptly removed to prevent the spread of disease and boost the tree’s overall health.
3. Overcrowded canopy: If the tree’s canopy is dense and overcrowded, pruning is necessary to ameliorate air circulation and light penetration, promoting better growth and reducing the risk of disease.
4. Weak or narrow crotches: Weak or narrow crotches, where branches attach to the trunk, are prone to splitting and breaking. Pruning helps strengthen these attachments and reduce the risk of branch failure.
5. Multiple leaders: Young trees ideally have a single, dominant leader or central trunk. If the tree has multiple leaders competing for dominance, pruning is requisite to extricate competing stems and encourage a strong central leader.
6. Low-hanging branches: Branches that hang low to the ground obstruct pathways, interfere with structures, or impede visibility. Pruning these branches is good for access and safety.
7. Deformed growth: If the tree has irregular or misshapen growth, pruning supports correcting its form and promoting a more balanced and aesthetically pleasing appearance.

What Are Some of the Common Pruning Techniques for Young Trees?

The following are some standard pruning techniques critical for young trees to grow well and live long:

1. Removing damaged branches: Trim away broken, defective, or damaged branches to prevent future issues. 
2. Structural or subordination pruning: Encourage the tree’s leader to grow by trimming competing branches, preventing future structural defects.
3. Training for proper growth: Prune to provide a stable structure and prevent the tree from branching out in the wrong direction. 
4. Selective branch removal: Expel lower lateral branches for several years to promote good growth and long-term structural integrity. 
5. Identifying and removing problematic branches: Remove branches with poor attachments, including bark or those that rub against each other or the main stem. It’s crucial to start pruning at the time of planting and to avoid over-thinning the tree’s crown excessively.

What Are Some Common Tools Needed for Pruning Young Trees?

Having the right tools for the job ensures that you can prune young trees safely and effectively. Common tools for lopping young trees include:

1. Hand pruners: These are essential for making precise cuts on small branches and twigs. Choose bypass pruners for clean cuts and reduced risk of crushing delicate stems.
2. Loppers: Loppers have longer handles than hand pruners, making them suitable for cutting thicker branches up to about 1.5 inches in diameter.
3. Pruning saw: A pruning saw with a curved blade is ideal for cutting larger branches. Look for a saw with sharp teeth and a comfortable handle for efficient and safe cutting.
4. Pole pruner: A pole pruner with a telescoping handle allows you to reach higher branches without the need for a ladder. It typically has a saw blade or bypass pruner attached to the end of a long pole.
5. Hedge shears: Hedge shears are useful for fashioning and maintaining the density of dense foliage, particularly for formal hedges or topiary shapes.
6. Pruning knife: A pruning knife with a sharp, curved blade is handy for making detailed cuts and removing small branches or shoots.
7. Safety gear: Don’t forget to wear safety gear such as gloves, eye protection, and sturdy footwear to protect yourself from cuts, scratches, and falling debris while pruning.

How Do You Prune Young Trees?

• Pruning shears are hand-held and cut branches and twigs up to ¾ of an inch thick, while loppers are great for branches up to 2 ½ inches wide. 
• Pruning saws three to five inches in diameter are perfect for cutting limbs, and hedge shears are great for hedges, small shrubs, evergreens, or deadheading perennials. 
• Use pole pruners to reach dead wood in trees or for light pruning and cut through branches up to 1 ¼ inch in diameter. 
• Keep the tools sharp, oiled, and free from rust, and sanitize them between trees with at least 70% denatured alcohol to prevent the spread of diseases.

What Are Safety Precautions Used When Pruning Young Trees?

When pruning young trees, it’s important to prioritize safety to prevent accidents and injuries. Here are some safety precautions to follow:

1. Wear appropriate safety gear: Always wear gloves, safety glasses or goggles, and sturdy footwear to protect your hands, eyes, and feet from cuts, scratches, and falling debris.
2. Use the right tools: Ensure that your pruning tools are in good condition and appropriate for the task at hand. Use sharp, well-maintained tools to make clean cuts and reduce the risk of accidents.
3. Be mindful of overhead hazards: Be aware of overhead power lines, branches, or other obstacles that pose a hazard while pruning. Avoid working near power lines and exercise caution when pruning branches overhead.
4. Use proper ladder safety: If using a ladder to reach higher branches, choose a sturdy, well-maintained ladder and set it up on level ground. Use caution when climbing and always maintain three points of contact with the ladder (two hands and one foot or two feet and one hand).
5. Work with a partner: If possible, have someone assist you while pruning, especially when using ladders or working with larger branches. A partner stabilizes the ladder, holds branches out of the way, or provides assistance in case of an emergency.
6. Plan your cuts: Before making any cuts, carefully assess the branch and plan your cuts to avoid accidentally removing more than intended or causing damage to the tree.
7. Follow proper pruning techniques: Use proper pruning techniques, such as making clean cuts just outside the branch collar or bark ridge, to promote proper healing and minimize the risk of disease or decay.
8. Take breaks as needed: Pruning is physically demanding work, especially when working on larger trees or for extended periods. Take frequent breaks to rest and hydrate to prevent fatigue and maintain focus.

What Injuries Occur When Pruning Young Trees?

The following are some potential injuries, and take the necessary precautions to ensure safe and effective tree pruning.

1. Improper pruning damage: This causes stunted growth, reduced foliage, visible decay, and large wounds, affecting the tree’s health and structural integrity.
2. Personal injuries: These result from being struck by falling objects, falls, cuts, amputations, eye injuries, and scrapes.
3. Safety hazards: Pruning-related safety hazards include branches obstructing the line of sight, crossed branches causing injuries, and trees growing too close to power lines, which are hazardous and cause damage in storms.
4. Tree wounds: Pollarding results in intentional wounds, and improper pruning attracts pests and diseases, affecting the tree’s health and longevity.

Homeowners perform clipping young trees. Start pruning at the time of planting and follow proper practices to ensure the abiding health and vitality of the tree. However, a certified arborist always comes in handy to understand the best pruning practices to ensure the tree’s health and longevity.

How do I promote healthy growth after pruning a young tree?

After pruning a young tree, monitor the tree for signs of stress and provide proper care, such as watering and fertilizing. Applying a layer of mulch around the tree’s base supports retaining moisture and protects the roots. Regular inspections and maintenance pruning as the tree grows help ensure its long-term health and vitality.
