Espalier Fruit Trees: Frank P Matthews’ Training & Care Guide

What is an espalier fruit tree, and how do you prune and care for one? This guide covers rootstock selection, tier training, and seasonal pruning instructions from the tree care experts at Frank P Matthews.

What is an Espalier Fruit Tree?

An espalier is a trained fruit tree grown flat against a wall, fence, or wire frame. It features a central vertical trunk with symmetrical horizontal tiers of branches extending outward on a single flat plane.

The word Espalier comes from the Italian spalla, meaning shoulder. Although the term Espalier is often used to describe any trained tree, the true form has branches coming out at 90 degrees from the main stem, creating an attractive regimented shape.

Espaliers have been utilized since Ancient Egypt where hieroglyphs of espaliered fig trees have been found in tombs dating back to 1400 B.C. They have also been used in medieval castles and courtyards to save space and in the gardens of Versailles.

Quick Summary: Espaliers are ideal for small gardens and narrow spaces. By training spur-bearing fruit trees (like apples and pears) flat against walls, gardeners maximise sunlight, harvest more efficiently, and protect early spring blossoms from frost using radiated wall heat.

Key Benefits of Espalier Fruit Trees

• – Space Efficiency: Fits fruit production into narrow walkways, fence lines, and urban plots.
• – Microclimate Benefits: Stone and brick walls radiate heat, which speeds up fruit ripening and guards blossoms against late frosts.
• – Simplified Maintenance: Pruning, fruit thinning, pest netting, and harvesting happen on one easily accessible flat surface.

Which Fruit Varieties and Rootstocks works best for espaliers?

Not all fruit trees are suitable for espalier training. Success depends on selecting spur-bearing fruit varieties and semi-vigorous rootstocks, which provide the right balance of growth and fruit production. There are two routes you can take: start with a one-year-old bare-root maiden tree and train it yourself, or choose a ready-trained espalier in a 12L container for an instant garden feature and earlier results.

Suitable vs. Unsuitable Fruit Types

• Apples & Pears (Recommended): Produce fruit on short, permanent side shoots called spurs, making them ideal for formal geometric training.
• Stone Fruits (Avoid for Espaliers): Plums, cherries, peaches, and apricots have brittle wood and bear fruit differently. Train stone fruits as fan-trained trees instead.
  

Recommended Espalier Rootstocks
Espaliers require semi-vigorous rootstocks. Weak dwarfing rootstocks lack the vigour needed to recover from regular pruning, while overly vigorous rootstocks become difficult to manage.

How do you train a 1 year Maiden Espalier Tree?

The golden rule of espalier training is patience: build only one horizontal tier per year. Rushing to grow multiple tiers in a single season produces weak lower branches that yield poor crops.

Step 1: Year 1 Spring Cut
Before the end of March, cut the central leader hard above three buds at 40–45 cm above the ground (or just above your bottom horizontal wire). This hard pruning triggers strong side-shoot development.

Step 2: Year 1 Summer Tying (early July)
Before new shoots become rigid:

1. Train the top shoot vertically up a cane support to form the main leader.
2. Tie the second and third side shoots out at a 45-degree angle to the left and right.
3. In late summer, gently lower these two side shoots to a flat horizontal position and secure them with soft twine.

Step 3: Year 2 Second Tier
In spring, cut the main vertical leader 45 cm above the first tier (or at the level of the second support wire). Repeat the Year 1 process of tying in two new side shoots to create your second horizontal tier.

How Do You Prune and Maintain Established Espaliers?

Regular pruning maintains the tree’s geometric outline and stimulates heavy fruit spur production.

Summer Spur Pruning (Late June – Late July)

Prune all vertical side shoots growing directly off the horizontal tiers back to two buds. This stops excess foliage growth and forces the tree to produce fruiting spurs.

Winter Pruning (February – March)

1. Vertical Regrowth: Cut back any vertical growth that sprouted from summer pruning points to one bud.
2. Central Leader: Cut the vertical leader back to the next support wire level.
3. Horizontal Branch Extensions: Tip back the ends of horizontal branches to a downward-facing bud, leaving 20–25 cm of the previous year’s extension growth.

Frequently Asked Questions About Espaliers

How far should an espalier tree be planted from a wall?
Plant espalier trees 15–25 cm away from the wall or fence. This gap ensures sufficient airflow behind the foliage, preventing fungal diseases like mildew and rot.

What is a step-over espalier tree?
A step-over is a single-tier espalier grown approximately 30–45 cm off the ground. Step-overs are used as decorative, edible borders along pathways or vegetable beds.

Can you espalier a tip-bearing fruit tree?
No. Tip-bearing trees produce fruit at the ends of new shoots, which would be pruned away during espalier maintenance. Always choose spur-bearing varieties for espaliers.

Where can I purchase an Espalier Tree?
