How to Maintain the Desired Shape of an Espalier Tree

Definition: Espalier is a horticultural technique used to train trees or shrubs to grow in a flat, two-dimensional form against a wall, fence, or trellis. Maintaining the desired shape of an espalier tree involves regular pruning and training to encourage the growth of branches in specific directions.

Pruning

Pruning is a crucial aspect of maintaining the desired shape of an espalier tree. It involves selectively removing branches and shoots to control growth and encourage the tree to grow in the desired pattern.

When pruning an espalier tree, it is important to follow these steps:

Remove unwanted growth: Identify any branches or shoots that are growing in the wrong direction or outside the desired shape. Use sharp pruning shears to carefully remove these unwanted growths.

Encourage lateral growth: To maintain the flat, two-dimensional form of the espalier tree, it is essential to encourage lateral growth. Prune the main stem or central leader to promote the growth of side branches.

Train branches: As the tree grows, gently tie the branches to the support structure using soft plant ties or twine. This will help guide the branches in the desired direction and maintain the overall shape of the espalier.

Regular maintenance: Prune your espalier tree regularly, at least once a year, to remove any new growth that deviates from the desired shape. This will help keep the tree looking neat and well-maintained.

Training

Training an espalier tree involves guiding the growth of branches in specific directions to achieve the desired shape. Here are some techniques for training an espalier tree:

• Horizontal training: For horizontal espaliers, such as the cordon or fan shape, train the branches to grow parallel to the ground. Use plant ties or twine to secure the branches to the support structure, ensuring they are evenly spaced.
• Vertical training: Vertical espaliers, such as the candelabra or Belgian fence shape, require training the branches to grow vertically. Attach the branches to the support structure using plant ties, making sure they are evenly spaced and growing straight upwards.
• Pruning for shape: During the training process, prune the branches to maintain the desired shape. This may involve removing excess growth, shortening branches, or encouraging lateral growth.
