Fruit Tree Care - Pruning

Pruning is both a science and an art when it comes to fruit tree cultivation. It involves selectively removing branches to shape the tree, improve its health, and maximize fruit production. One of the key decisions in pruning fruit trees is choosing the appropriate shape. In this blog post, we will delve into the art of pruning and explore different shapes for fruit trees, highlighting their benefits and considerations.

Pruning Shapes - Open Centre, Central Leader, Espalier, and Palmette

Open Center or Vase Shape: The open center, also known as the vase shape, is a popular choice for many fruit trees, including apples, peaches, and plums. This shape features a central leader (main trunk) and multiple well-spaced branches that radiate outwards, creating a vase-like structure. Benefits of the open center shape include:

• Enhanced sunlight penetration, promoting optimal fruit development.

• Improved air circulation, reducing the risk of fungal diseases.

• Ease of harvesting, with fruits accessible from all sides.

• Balanced growth, with less chance of branch breakage under heavy fruit load.

As you can see here, this form is commonly used in apple orchards, where the central leader is removed giving the recognisable apple tree shape.

Central Leader or Christmas Tree Shape: The central leader shape resembles a traditional Christmas tree, with a single, dominant central trunk and tiers of horizontally arranged branches. This shape is well-suited for trees like pears and some varieties of apples. Advantages of the central leader shape include:

• Strong and sturdy structure, capable of supporting heavy fruit loads.

• Easy management of tree height by controlling the central leader's growth.

• Clear visibility of all branches, facilitating pruning and maintenance.

• Straight and uniform growth, ideal for orchard settings.

Here is an orchard of mature apple trees pruned to the central leader form to enable more trees to be grown in less space:

Espalier or Wall-Training Shape: Espalier is a unique and aesthetically appealing pruning technique where fruit trees are trained to grow in a flat, two-dimensional pattern against a wall or trellis, commonly seen in kitchen gardens. This shape is commonly used for apple, pear, and peach trees.

Benefits of espalier include:

• Maximization of limited space, making it ideal for small gardens or urban areas.

• Efficient use of sunlight, resulting in improved fruit quality and ripening.

• Easy access for maintenance, harvesting, and pest management.

• Attractive and decorative appearance, adding charm to garden landscapes.

Here is a demonstration of a mature tree pruned to the espalier form, with a main trained branch against a wall -

The wall trained shape is a desirable one for an aesthetic touch in a walled garden, using less utilised space to create an artistic wall of fruit. Perfect for smaller spaces and reducing the shadow footprint of a tree.

Palmette Shape: The palmette shape is characterized by angled trained branches that radiate from a central trunk, resembling a fan shape. This form is often used for apple and pear trees. Advantages of the palmette shape include:

• Excellent light exposure for all branches, ensuring uniform fruit development.

• Compact design, making it suitable for small gardens or espalier fences.

• Easy maintenance and harvesting due to the branches' accessibility.

• Versatility, allowing for variations such as single-tier or multiple-tier palmette shapes.

Here is an example of a mature fruit tree pruned to the palmette form -

Branches angled 45 degrees from a horizontal position give a beautiful fanned shape that can be trained against a wall, similarly to the espalier form.

Considerations for Pruning Fruit Trees

There are several aspects to consider before getting out those pruners! Shape pruning of fruit trees is a necessary but ongoing process over years to maximise the health and bounty from your tree.

Here are a few things to think about:

• Choose the appropriate shape based on the tree's growth habit, available space, and personal preferences.

• Regular maintenance pruning is crucial to maintain the desired shape and optimize fruit production. So choose a shape that you will be able to maintain and brings the most to the space.

Key things to remember:

• Prune during the dormant season (winter or early spring) to minimize stress and reduce the risk of diseases. Or alternatively, you can prune certain fruits just after harvesting to create new fruiting branches for the following year.

• Use sharp and clean pruning tools to make precise cuts and prevent the introduction and spread of disease.

• Aim for an open canopy, avoiding excessive branch crossing or overcrowding in order to produce the most fruit and prevent disease from low air flow.

• Pay attention to the tree's response to pruning and adjust techniques accordingly in subsequent years.

Pruning fruit trees is an essential practice for shaping their growth, improving health, and maximizing fruit production. By selecting the right shape for your specific fruit tree and applying proper pruning techniques, you can create an aesthetically pleasing and fruitful addition to your garden or orchard. Remember to consider the tree's growth habit, available space, and maintenance requirements when choosing a shape. With the art of pruning in your hands, you can sculpt your fruit trees into beautiful and bountiful masterpieces for years to come.
