Companion planting is a gardening technique where different plant species are grown alongside each other to provide benefits such as improved pest control, enhanced nutrient availability, and increased pollination. One popular technique used in companion planting is espalier, which involves training plants to grow against a flat surface, such as a wall or fence, in a specific pattern or shape.
What is Espalier?
Espalier is a horticultural practice that dates back centuries and originated in Europe. It involves pruning and training plants to grow in a two-dimensional form against a support structure. The plants are usually trained in either a vertical or horizontal manner, creating a living fence or wall of foliage. Espaliered plants are not only aesthetically pleasing but also practical, as they occupy less space and are easier to manage compared to traditional sprawling plants.
Shapes and Forms
In an espalier system, plants can be trained into various shapes and forms, depending on the gardener's preference and the specific requirements of the plant species. Some common shapes include the candelabra, fan, cordon, and Belgian fence.
Candelabra
A candelabra espalier involves training the main stem of a plant upward while allowing lateral branches to grow horizontally. This shape resembles the shape of a candelabra or a tree-like structure with multiple branches.
Fan
A fan espalier creates a decorative pattern resembling a handheld fan. The main stem is trained vertically, while branches are pruned and trained to fan out horizontally on either side.
Cordon
A cordon espalier is characterized by a single vertical stem with multiple horizontal branches growing in a single plane. This shape is particularly suitable for fruit trees, as it maximizes exposure to sunlight and increases fruit production.
Belgian Fence
A Belgian fence espalier is a more intricate form that involves a crisscross pattern of horizontal branches. This creates a unique and visually striking effect, resembling a lattice-like fence or trellis covered in foliage.
Espalier and Companion Planting
Espalier fits well within the concept of companion planting, as it allows for the inclusion of multiple plant species in a confined space. In a companion planting system, espaliered plants can be strategically positioned alongside other plants to create mutually beneficial relationships.
For example, a vegetable garden may incorporate espaliered fruit trees as a protective border, serving as a windbreak or shade provider for vegetable crops. The fruit trees, in turn, benefit from increased pollination and pest control provided by the nearby vegetables.
Similarly, flowering plants or herbs can be included in an espalier system to attract beneficial insects, such as pollinators and predators of garden pests. The proximity of different plant species also helps create a diverse microclimate, enhancing overall garden health.
Benefits of Training Espaliered Plants in Companion Planting
Combining espalier and companion planting offers several advantages:
- Space Optimization: Espaliered plants take up less space than traditional plants, allowing for more efficient use of small gardens or urban spaces.
- Increased Yield: Training fruit trees in espalier shapes exposes more branches to sunlight, resulting in increased fruit production.
- Pest Control: Proximity to other plant species can attract beneficial insects that help control garden pests, reducing the need for chemical pesticides.
- Nutrient Availability: Companion plants can improve soil quality and nutrient availability for the espaliered plants, promoting healthy growth.
- Aesthetically Pleasing: The trained forms of espaliered plants create visually stunning patterns and structures, enhancing the overall appearance of the garden.
Conclusion
Espaliered plants can indeed be trained into specific shapes or forms in a companion planting system. This technique offers numerous benefits, including space optimization, increased yield, improved pest control, enhanced nutrient availability, and aesthetically pleasing garden designs. By combining espalier and companion planting, gardeners can create harmonious and productive gardens that maximize both functionality and beauty.
