Overview of Pruning

Importance of Pruning Fruit Trees

Pruning fruit trees is essential for maintaining healthy growth and maximizing fruit production. By learning how to prune fruit trees, including an apple tree, cherry trees, and nut trees, you can encourage the development of strong scaffold branches and improve the overall tree structure.

Whether working with newly planted trees, mature trees, or neglected fruit trees, pruning and training helps to remove diseased branches, make thinning cuts for better light penetration, and promote the growth of new shoots.

Techniques like central leader training, modified central leader form, and summer pruning are crucial for managing lateral branches, vertical branches, and the entire tree for optimal fruit and nut production.

The Benefits of Proper Pruning

Proper pruning of fruit trees offers numerous benefits, enhancing both tree health and fruit production. By understanding how to prune fruit trees, such as an apple tree, cherry trees, and stone fruit trees, you can encourage strong scaffold branches and improve the overall tree structure.

Regular pruning and training of young trees, mature trees, and even neglected fruit trees helps to remove dead or diseased branches, make thinning cuts, and allow better light penetration, promoting vigorous shoot growth. Focus on the center of the tree to ensure optimal air circulation and sunlight exposure.

Techniques like central leader training, summer pruning, and detailed pruning of lateral branches and upright branches ensure that fruit and nut trees, including the apple tree, bear fruit more effectively throughout their growing season.

You're ready to plant a fruit tree -- but how do you decide on the best pruning and training system? We've got easy answers for you. The University of California says pruning and training your fruit tree will improve it five ways:

• Keep it a manageable size
• Grow larger fruit
• Ensure a yearly crop
• Let light and air into the lower branches
• Renew the vigor of the tree

The three most popular shapes for fruit trees are Central Leader, Vase (or Open Center), and Modified Central Leader. Certain kinds of fruit trees are most productive with certain shapes. Some kinds of fruit trees can be trained in almost any way. We'll show you the three shapes and list the trees that work best in that shape. In our video series, Tricia prunes in each of these shapes -- just follow the links below to watch the pertinent video.

Understanding the Basics of Fruit Tree Pruning

What is Pruning?

Pruning is essential for maintaining the health and productivity of fruit trees, whether they are newly planted trees or mature apple trees. Understanding how to prune fruit trees involves recognizing the purpose of various pruning cuts and techniques, such as thinning cuts and summer pruning, to encourage optimal fruit production.

For example, learning how to prune apple trees or stone fruit trees involves creating a balanced structure by managing scaffold branches and promoting lateral branches, while also removing dead limbs and diseased branches. When pruning, focus on the center of the tree to improve air circulation and light penetration. Additionally, pruning encourages the growth of leaf buds for a more productive growing season. Effective pruning and training not only enhances tree structure but also helps fruit trees bear fruit more efficiently.

How Pruning Affects Fruit Tree Growth

Understanding how to prune fruit trees is crucial for optimizing their growth and fruit production. Pruning apple trees, as well as other fruit trees like cherry trees, involves techniques like summer pruning and thinning cuts to manage tree structure and improve light penetration.

Proper pruning helps to develop a strong central leader or modified central leader form, which supports vigorous shoot growth and balanced fruiting. When pruning apple trees, it’s important to focus on developing scaffold branches that will form the tree’s framework for healthy fruiting.

By strategically removing large branches, dead branches, and crowded limbs, gardeners can improve the overall health of a mature apple tree, encouraging it to bear fruit more effectively and efficiently.

Central Leader training system

This diagram from the University of Missouri Extension shows how to prune in the Central Leader system from planting on through the third year. Watch our video to see Tricia prune and train a fruit tree with a Central Leader. A Central Leader shape is a conical, "Christmas tree" that is tall and tapered. The shape give the highest production, due to the light and air circulation, but it grows too tall to be practical for most home orchards. A home gardener can use this training system, though, when working with a dwarf tree. A successful shape for: Apple, pear, persimmon & pecan trees.

Vase or Open Center training system

The University of Missouri Extension illustrates pruning in the Vase (or Open Center) system from planting on through the third year. Tricia prunes and trains a Vase shaped fruit tree in our first video. The Vase is the simplest shape for beginning orchardists to prune, and allows plentiful sunlight in its open center. The drawbacks are weak branches that need props when bearing fruit, and heavy shade that can develop from leaves on the upper branches of the tree. A traditional shape for: Almond, apricot, cherry, fig, nectarine, olive, peach, pear, persimmon, plum & pomegranate trees.

Modified Central Leader training system

Modified Central Leader is the compromise shape. Here is a diagram of how to prune a tree according to this training system during its first four years from the Virginia Cooperative Extension. Watch our video to see how Tricia prunes and trains a fruit tree in this popular, all-purpose style. Combining the best features of both the Central Leader and Vase systems (sturdy trunk and central light) the Modified Central Leader is the default choice. Easier to harvest than a tall Central Leader tree, and with stronger branches than an Open tree, this is also the best choice for all fruit trees in the sunny Southwest. A good choice for: Almond, apple, apricot, cherry, fig, nectarine, olive, peach, pear, pecan, persimmon, plum, pluot, pomegranate & walnut trees.

What do these three training systems have in common? They all require sharp pruning tools!

Do you need to replace any of your pruning tools? We test pruning tools in our own orchards and recommend this select group for you, in a variety of price ranges. In the Modified Central Leader video Tricia uses the new Corona ComfortGEL handled 3/4" Bypass Pruners and 30" Bypass Loppers.

Types of Fruit Trees and Their Specific Pruning Needs

Deciduous vs. Evergreen Fruit Trees

Pruning fruit trees effectively depends on whether they are deciduous or evergreen. Deciduous fruit trees, such as apple trees and pear trees, often require distinct pruning techniques like summer pruning and winter pruning to manage their growth and enhance fruit production.

For these trees, understanding how to prune fruit trees involves focusing on removing large branches, training young trees, and managing scaffold branches to develop a strong central leader or modified central leader form.

In contrast, evergreen fruit trees, including some nut trees and citrus, have different needs, with pruning typically aimed at maintaining tree structure and encouraging healthy new shoots without removing as many branches.

Pruning Techniques for Popular Fruit Trees

Different types of fruit trees have specific pruning needs to optimize their growth and fruit production. For apple trees, central leader training and thinning cuts are essential to encourage a strong tree structure and the development of scaffold branches.

Stone fruit trees like peach, plum, and cherry trees benefit from summer pruning to manage lateral branches and promote light penetration, while pear trees often require a modified central leader form to support their upright branches.

Citrus and fig trees, being vigorous trees, need detailed pruning and maintenance pruning to remove dead limbs and encourage the growth of new shoots throughout the growing season.

When to Prune: Timing Is Everything

Best Time of Year to Prune Different Fruit Trees

The best time to prune fruit trees varies based on the season and the type of tree. Winter pruning, performed during the tree's dormant period, is ideal for apple trees, pear trees, and other deciduous fruit trees, as it helps to shape the tree and remove large branches without disrupting new shoots.

Summer pruning, on the other hand, is beneficial for stone fruit trees like peach and cherry, as it encourages lateral branches and manages vigorous growth to improve fruit production.

Spring and fall pruning considerations include focusing on newly planted trees and addressing any neglected fruit trees to ensure healthy growth and optimal fruit yield throughout the growing season.

Understanding Tree Dormancy

Understanding tree dormancy is crucial for effective pruning and overall tree health. Dormancy occurs when a fruit tree, such as apple trees or cherry trees, has ceased active growth and entered a resting phase, typically in winter.

During this period, signs of dormancy include the absence of new shoots and the tree’s leaves dropping, making it the ideal time for winter pruning to shape the tree and remove large branches without disrupting its growth cycle.

Recognizing these signs ensures that you can properly manage your fruit and nut trees, including young trees and mature trees, enhancing their structure and fruit production for the upcoming growing season.

Tools and Equipment for Pruning

Essential Pruning Tools

Essential pruning tools are crucial for effective tree care and achieving optimal results when pruning fruit trees. Pruning shears are ideal for cutting small branches and managing young apple trees or newly planted trees, while loppers handle larger branches and can reach deeper into the tree center.

Pruning saws are essential for removing larger branches and tackling mature trees or neglected fruit trees, ensuring clean pruning cuts that minimize pruning wounds.

For higher or more challenging areas, pole pruners allow you to reach vertical branches and horizontal branches, making them valuable for maintaining a well-structured and healthy tree.

Maintenance and Safety Tips for Pruning Tools

Proper maintenance and safety are essential for effective pruning and the longevity of your tools. Regularly sharpening pruning tools, such as shears and loppers, ensures clean cuts and minimizes pruning wounds on fruit trees, including apple trees and young apple trees.

Always wear appropriate safety gear, such as gloves and eye protection, to avoid injury from falling branches or accidental cuts.

Additionally, inspecting tools for damage before use and practicing correct handling techniques will help you safely manage growing fruit trees and maintain tree health, whether you're addressing neglected trees or caring for mature trees.

Pruning Techniques: Step-by-Step Guide

Basic Pruning Techniques

• Thinning:

  • Identify Target Branches: Look for crowded or overlapping branches, as well as any that are diseased or damaged.

  • Make the Cut: Using sharp pruning shears or loppers, remove entire branches at their point of origin or close to the branch bark ridge. This opens up the tree's canopy, allowing light to penetrate and air to circulate.

  • Review Tree Structure: Ensure that the remaining branches are well-spaced and support the desired tree structure, whether it’s a central leader system or multiple leader tree.

• Heading:

  • Select Branches to Shorten: Focus on branches that need to be shortened to encourage new growth or to maintain the tree's shape.

  • Make the Cut: Use pruning shears or a saw to cut the branches back to a lateral branch or bud. This will stimulate new shoots to grow from the cut point.

  • Check Growth: After heading, monitor the tree to ensure that the new shoots grow as desired and that the tree maintains a balanced structure.

• Pinching:

  • Locate New Growth Tips: Identify the soft, young tips of branches that are growing vigorously.

  • Pinch the Tips: Using your fingers or pruning shears, gently remove the tip of the new growth. This encourages the plant to produce more lateral branches and helps control the tree’s size.

  • Monitor Development: Keep an eye on the tree’s response to pinching, adjusting your technique as needed to manage growth and improve fruit production.

Advanced Pruning Techniques

• Espalier Pruning:

  • Select a Framework: Choose a wall, trellis, or other structure for training the tree. Ensure it is suitable for supporting the growth of your fruit tree.

  • Initial Training: For young apple trees or other fruit trees, attach the branches to the framework using ties or clips, positioning them horizontally to form the desired shape.

  • Ongoing Maintenance: Regularly prune and adjust the branches to maintain the espalier form, removing unwanted growth and encouraging lateral branches to develop along the structure.

• Pollarding:

  • Choose the Right Time: Perform pollarding during the dormant season, typically in late winter or early spring, before new growth begins.

  • Cut Back to a Pollard Head: Remove all branches except for a few stubs or “pollard heads” on the main trunk or limbs. These stubs will produce new growth in the coming season.

  • Manage New Growth: As new shoots develop, selectively prune to maintain the desired shape and manage the tree’s size, ensuring a healthy balance and avoiding excessive strain on the tree.

• Coppicing:

  • Cut Back to the Base: In early winter or early spring, cut the tree back to ground level or a few inches above the base, depending on the species and desired outcome.

  • Encourage New Shoots: Allow the tree to sprout new shoots from the base. These new shoots will grow vigorously and can be used for various purposes.

  • Regular Maintenance: Periodically thin out the new shoots and manage their growth to maintain a balanced structure and prevent overcrowding, ensuring a continuous supply of new wood and maintaining the tree’s health.

Special Techniques for Young vs. Mature Trees

Special techniques for pruning young versus mature trees are crucial for effective tree management. For young apple trees and newly planted trees, focus on training young trees by establishing a central leader system and encouraging the growth of horizontal branches, which helps in developing a strong structure and permanent scaffold limbs.

In contrast, rejuvenating older trees like neglected fruit trees or mature trees involves more intensive pruning cuts to remove unproductive branches, thin out crowded growth, and address any structural issues, which helps in restoring vigor and improving fruit production.

Employing these techniques during appropriate seasons, such as early spring for rejuvenation and early summer for training, ensures healthy and productive fruit trees.

Common Pruning Mistakes and How to Avoid Them

Over-Pruning: How Much is Too Much?

Over-pruning is a common mistake that can severely impact the health and productivity of fruit trees. To avoid this, it's crucial to understand how to prune fruit trees properly, ensuring that you make selective pruning cuts rather than removing too many branches.

For young apple trees and mature trees, avoid cutting back too aggressively, as this can lead to excessive pruning wounds and reduced fruit production. Focus on maintaining a balanced structure by removing only necessary branches, such as those that are dead or diseased, while preserving key branches to support growth and fruiting.

Incorrect Cuts: Recognizing and Correcting Them

Incorrect cuts are a frequent issue when pruning fruit trees and can lead to poor growth or damage. To avoid this, it’s important to understand how to prune fruit trees properly by making precise pruning cuts that promote healthy branch growth.

For example, always cut just above the branch bark ridge to minimize pruning wounds and prevent disease. Avoid cutting too close to the trunk or leaving stubs, as these can harm the tree's structure and lead to complications, especially in mature trees or neglected fruit trees.

Proper technique helps maintain a balanced tree structure and supports robust growth and fruit production.

Ignoring Tree Health: Pruning and Disease Management

Ignoring tree health during pruning can lead to increased disease risk and compromised growth. To effectively manage both pruning and disease, ensure you know how to prune fruit trees by making clean cuts at the branch bark ridge and avoiding unnecessary wounds.

For both young apple trees and mature trees, regularly inspect for signs of disease and remove affected branches promptly to prevent spread.

Avoid pruning during periods of high disease activity and use sanitized pruning tools to minimize the risk of introducing pathogens to growing fruit trees or neglected fruit trees.
