Tree Trimming Before And After (Pro Pruning Techniques Revealed)

Understanding Tree Trimming: The Foundation for Success

Before we dive into specific techniques, it’s crucial to understand the “why” behind tree trimming. It’s not just about making trees look pretty; it’s about promoting their long-term health and structural integrity.

Why Prune Trees? The Core Benefits

Health Improvement: Removing dead, diseased, or damaged branches prevents the spread of infection and encourages new, healthy growth.
Structural Integrity: Pruning weak or crossing branches reduces the risk of breakage during storms and creates a stronger overall structure.
Aesthetic Enhancement: Shaping the tree can improve its appearance and maintain a desired form.
Safety: Removing branches that obstruct walkways, power lines, or visibility ensures a safer environment.
Increased Fruit Production: For fruit trees, pruning can significantly increase fruit yield and quality.
Light and Air Penetration: Opening up the canopy allows more sunlight and air to reach the inner branches, promoting healthy growth and reducing the risk of fungal diseases.

Key Terminology: Speaking the Language of Pruning

To effectively communicate about tree trimming, it’s essential to understand the basic terminology:

Leader: The main, dominant stem of the tree.
Lateral Branch: Branches that grow from the main stem.
Terminal Bud: The bud at the end of a branch.
Lateral Bud: Buds along the sides of a branch.
Branch Collar: The swollen area at the base of a branch where it attaches to the trunk. This is crucial to protect during pruning.
Branch Bark Ridge: The raised area of bark on the upper side of the branch union.
Suckers: Shoots that grow from the roots or base of the trunk.
Water Sprouts: Shoots that grow from the branches, often vertically and vigorously.
Deadwood: Dead branches.
Crossing Branches: Branches that rub against each other.
Included Bark: Bark that grows inward at the crotch of a branch union, creating a weak point.
Crotch Angle: The angle formed between a branch and the trunk. Stronger unions have wider crotch angles.

Tools of the Trade: Equipping Yourself for Success

Having the right tools is essential for safe and effective tree trimming. Quality tools not only make the job easier but also reduce the risk of injury and damage to the tree.

Chainsaw Selection:

Size and Power: Choose a chainsaw with a bar length and engine size appropriate for the size of the trees you will be working on. A smaller chainsaw (14-16 inch bar) is sufficient for most pruning tasks, while larger trees may require a larger chainsaw (18-20 inch bar or larger).
Type: Chainsaws are available in gas-powered, electric, and battery-powered models. Gas-powered chainsaws offer the most power and portability, while electric and battery-powered chainsaws are quieter and require less maintenance.
Features: Look for features such as a chain brake, anti-vibration system, and automatic chain oiler. These features will improve safety and comfort.
Brand: Choose a reputable brand known for quality and reliability. Stihl, Husqvarna, and Echo are popular choices.

Chainsaw Maintenance:

Chain Sharpening: A sharp chain is essential for safe and efficient cutting. Sharpen the chain regularly using a chainsaw file or a chain grinder. I personally prefer using a chainsaw file for field sharpening, as it allows me to maintain the chain’s edge without removing it from the saw.
Chain Lubrication: Keep the chain properly lubricated with chainsaw bar oil. Check the oil level regularly and refill as needed.
Air Filter Cleaning: Clean the air filter regularly to ensure proper engine performance.
Spark Plug Replacement: Replace the spark plug annually or as needed.
Fuel Mixture: Use the correct fuel mixture for your chainsaw. Consult the owner’s manual for the proper ratio of gasoline to oil.
Chain Tension: Check the chain tension regularly and adjust as needed. A loose chain can derail and cause injury.
Bar Maintenance: Clean the bar regularly and remove any burrs or damage.
Storage: Store the chainsaw properly when not in use. Drain the fuel tank and clean the saw.

Pruning Techniques: Mastering the Art of the Cut

Now that we have the tools and terminology covered, let’s move on to the actual pruning techniques. Different pruning techniques are used for different purposes.

The Three-Cut Method: Safely Removing Large Branches

When removing large branches, the three-cut method is essential to prevent bark stripping and damage to the trunk.

Undercut: Make an undercut about 12-18 inches from the branch collar, cutting about one-third of the way through the branch. This prevents the bark from tearing when the branch falls.
Top Cut: Make a top cut a few inches further out from the undercut, cutting all the way through the branch. The branch will fall away, leaving a stub.
Final Cut: Make the final cut just outside the branch collar, cutting at a slight angle to avoid damaging the collar. This cut promotes proper wound healing.

Branch Collar Pruning: The Key to Wound Healing

The branch collar is the swollen area at the base of a branch where it attaches to the trunk. It contains specialized cells that are essential for wound closure. When pruning, it’s crucial to avoid damaging the branch collar.

Avoid Flush Cuts: Flush cuts, which remove the branch collar entirely, prevent proper wound healing and can lead to decay.
Cut Just Outside the Branch Collar: Make the final cut just outside the branch collar, leaving a small stub. The stub should be no more than 1/2 inch long.
Angle the Cut: Angle the cut slightly to match the angle of the branch collar.

Thinning Cuts: Opening Up the Canopy

Thinning cuts remove entire branches back to their point of origin. This technique is used to open up the canopy, improve air circulation, and reduce the overall density of the tree.

Remove Crossing Branches: Crossing branches rub against each other, causing damage and creating entry points for disease.
Remove Weak Branches: Weak branches are prone to breakage and can pose a safety hazard.
Remove Water Sprouts and Suckers: Water sprouts and suckers are unproductive and can detract from the tree’s appearance.
Maintain a Natural Shape: When thinning, try to maintain the tree’s natural shape. Avoid removing too many branches from one area.

Heading Cuts: Stimulating New Growth

Heading cuts shorten branches back to a bud or lateral branch. This technique stimulates new growth and can be used to control the size and shape of the tree. However, heading cuts can also create dense, unnatural growth if overused.

Cut Back to a Lateral Bud: When making a heading cut, cut back to a lateral bud that is pointing in the direction you want the new growth to go.
Angle the Cut: Angle the cut slightly away from the bud.
Avoid Stub Cuts: Stub cuts, which leave a long stub above the bud, can lead to dieback.

Reduction Cuts: Reducing the Size of a Branch or Stem

Reduction cuts reduce the size of a branch or stem by cutting it back to a lateral branch that is at least one-third the diameter of the cut stem. This technique is used to reduce the overall size of the tree or to redirect growth.

Cut Back to a Lateral Branch: When making a reduction cut, cut back to a lateral branch that is at least one-third the diameter of the cut stem.
Angle the Cut: Angle the cut slightly away from the lateral branch.
Maintain a Natural Shape: When making reduction cuts, try to maintain the tree’s natural shape.

Pruning for Different Tree Types: Tailoring Your Approach

Different tree types require different pruning techniques.

Pruning Fruit Trees: Maximizing Fruit Production

Fruit trees are pruned to maximize fruit production.

Dormant Pruning: Fruit trees are typically pruned during the dormant season (late winter or early spring).
Remove Dead, Diseased, and Damaged Wood: Remove any dead, diseased, or damaged wood.
Open Up the Canopy: Open up the canopy to allow more sunlight to reach the inner branches.
Thin Out Fruit-Bearing Branches: Thin out fruit-bearing branches to prevent overcrowding and improve fruit size and quality.
Train the Tree: Train the tree to a desired shape, such as a central leader or open center.

Pruning Shade Trees: Maintaining Health and Structure

Shade trees are pruned to maintain their health and structure.

Remove Dead, Diseased, and Damaged Wood: Remove any dead, diseased, or damaged wood.
Remove Crossing Branches: Remove crossing branches to prevent damage and improve air circulation.
Raise the Canopy: Raise the canopy by removing lower branches to provide clearance for walkways and buildings.
Thin Out the Canopy: Thin out the canopy to allow more sunlight to reach the ground below.
Maintain a Natural Shape: Maintain the tree’s natural shape.

Pruning Ornamental Trees: Enhancing Aesthetics

Ornamental trees are pruned to enhance their aesthetics.

Remove Dead, Diseased, and Damaged Wood: Remove any dead, diseased, or damaged wood.

Pruning Conifers: A Gentle Touch

Conifers generally require less pruning than deciduous trees.

Remove Dead, Diseased, and Damaged Wood: Remove any dead, diseased, or damaged wood.
Shape the Tree: Shape the tree to a desired form.
Avoid Severe Pruning: Avoid severe pruning, as conifers do not readily produce new growth from old wood.

When to Prune: Timing is Everything

The timing of pruning can significantly impact the tree’s health and growth.

Dormant Pruning: The Ideal Time for Most Trees

Dormant pruning, which is done in late winter or early spring before new growth begins, is the ideal time for most trees.

Easier to See the Structure: The absence of leaves makes it easier to see the tree’s structure and identify problem branches.
Stimulates New Growth: Dormant pruning stimulates new growth in the spring.
Reduced Risk of Disease: The risk of disease transmission is lower during the dormant season.

Summer Pruning: For Specific Needs

Summer pruning, which is done after the tree has leafed out, can be used to slow down growth or to remove water sprouts and suckers.

Slows Down Growth: Summer pruning can slow down growth by removing leaves that are needed for photosynthesis.
Removes Water Sprouts and Suckers: Summer pruning is a good time to remove water sprouts and suckers.
Can Stress the Tree: Summer pruning can stress the tree, so it should be done sparingly.

Pruning After Flowering: For Spring-Flowering Trees

Spring-flowering trees, such as azaleas and rhododendrons, should be pruned immediately after they finish flowering.

Avoids Removing Flower Buds: Pruning after flowering avoids removing the flower buds that will produce flowers the following spring.
Stimulates New Growth: Pruning after flowering stimulates new growth that will produce flower buds for the following year.

Safety First: Protecting Yourself and Others

Tree trimming can be dangerous, so it’s essential to prioritize safety.

Essential Safety Precautions: A Must-Follow List

Never Work Alone: Never work alone when using a chainsaw.

Case Studies: Real-World Applications

To illustrate the principles discussed, let’s examine a few case studies.

Case Study 1: Restoring an Overgrown Apple Tree

An apple tree in a neglected orchard was severely overgrown, with dense foliage and numerous crossing branches. Fruit production was minimal.

Problem: Overgrowth, poor air circulation, low fruit yield.
Solution: Dormant pruning using thinning cuts to open up the canopy, removing crossing branches and water sprouts. Heading cuts were used to shorten overly long branches and encourage fruit bud formation.
Results: Improved air circulation and sunlight penetration, increased fruit production in subsequent years, and a healthier, more aesthetically pleasing tree.
Key Takeaway: Consistent pruning, even after years of neglect, can revitalize fruit trees.

Case Study 2: Removing a Hazardous Branch Overhanging a House

A large oak tree had a dead branch that was overhanging a house, posing a significant safety hazard.

Problem: Hazardous dead branch.
Solution: Removal of the branch using the three-cut method, employing a pole saw for initial cuts and a chainsaw for the final cut. A rope was used to control the fall of the branch and prevent damage to the house.
Results: Removal of the hazardous branch, eliminating the risk of damage to the house.
Key Takeaway: Professional assistance is often necessary for removing large, hazardous branches, especially near structures.

Case Study 3: Shaping a Young Maple Tree

A young maple tree was growing unevenly, with one side significantly more developed than the other.

Problem: Uneven growth, asymmetrical shape.
Solution: Selective pruning using thinning cuts to remove some of the excess growth on the more developed side, and heading cuts to encourage growth on the less developed side.
Results: More balanced growth and a more symmetrical shape.
Key Takeaway: Early pruning can shape young trees and prevent future structural problems.

Disposal of Pruned Material: Sustainable Options

After pruning, you’ll need to dispose of the pruned material.

Sustainable Disposal Methods: Minimizing Environmental Impact

Chipping: Chipping branches and using the chips as mulch is a great way to recycle the material and improve soil health. I often use wood chips from pruning projects to mulch my vegetable garden, which helps retain moisture and suppress weeds.
Composting: Smaller branches and leaves can be composted.
Firewood: Larger branches can be cut into firewood. Remember to season the wood properly before burning it.
Woodworking: Some branches can be used for woodworking projects.
Professional Removal: If you have a large amount of material, you can hire a professional tree service to remove it.

Troubleshooting Common Pruning Problems: Addressing Challenges

Even with careful planning, problems can arise during pruning.

Common Pruning Mistakes and Solutions: Learning from Errors

Over-Pruning: Over-pruning can stress the tree and make it more susceptible to disease. I once witnessed a homeowner remove almost all the branches from a mature oak tree, resulting in severe decline. Avoid removing more than 25% of the tree’s foliage in a single year.
Flush Cuts: Flush cuts prevent proper wound healing and can lead to decay. Always cut just outside the branch collar.
Stub Cuts: Stub cuts can lead to dieback. Always cut back to a lateral bud or branch.
Improper Tool Use: Using the wrong tools or using tools improperly can damage the tree and increase the risk of injury. Use the right tools for the job and make sure they are in good working condition.
Ignoring Safety Precautions: Ignoring safety precautions can lead to serious injury. Always wear appropriate personal protective equipment (PPE) and follow safe work practices.
