Espalier is an ancient horticultural technique used to train fruit trees to grow flat against a wall or fence. This method not only saves space but also creates a stunning visual display and can increase fruit production. Here's how you can master the art of espalier in your UK garden.
#1. Choose the Right Tree
Not all fruit trees are suitable for espalier. The best choices are apple and pear trees, as they are flexible and respond well to training. Choose a variety that is known for its disease resistance and suitability for your local climate.
#2. Select the Right Location
Espaliered trees need plenty of sunlight to thrive and produce fruit. Choose a south-facing wall or fence that receives at least 6-8 hours of direct sunlight each day. Ensure the area has good drainage to prevent waterlogging.
#3. Prepare the Support Structure
Before planting your tree, install a sturdy support structure. This can be a series of horizontal wires attached to a wall or fence, spaced about 30cm (12 inches) apart. The wires will provide support for the branches as they grow and are trained into shape.
#4. Plant the Tree
Plant your tree about 15-20cm (6-8 inches) away from the wall or fence to allow for air circulation. Dig a hole that is twice the width of the root ball and the same depth. Place the tree in the hole, backfill with soil, and water thoroughly.
#5. Prune and Train the Tree
The key to successful espalier is regular pruning and training. Here's a step-by-step guide:
- Initial Pruning: After planting, prune the tree to about 30cm (12 inches) above the ground. This will encourage the growth of lateral branches.
- Select Main Branches: In the first year, select two strong lateral branches to form the first tier. Tie them to the horizontal wires using soft ties.
- Training: As the tree grows, continue to tie new growth to the wires, training the branches to grow horizontally. Remove any unwanted vertical growth.
- Annual Pruning: Each winter, prune the tree to maintain its shape and encourage fruiting spurs. Remove any dead, diseased, or crossing branches.
#6. Fertilise and Water
Espaliered trees need regular feeding and watering to thrive. Apply a balanced fertiliser in early spring and again in mid-summer. Water the tree deeply and consistently, especially during dry spells.
#7. Monitor for Pests and Diseases
Regularly inspect your espaliered tree for signs of pests and diseases. Common issues include aphids, apple scab, and powdery mildew. Use organic pest control methods and remove any affected leaves or branches promptly.
#8. Enjoy the Fruits of Your Labour
With proper care and attention, your espaliered tree will reward you with a bountiful harvest of delicious fruit. Enjoy the beauty and productivity of this ancient gardening technique in your own garden.
By following these tips, you can master the art of espalier and create a stunning and productive feature in your UK garden. Happy gardening!
