Espalier is a technique used in gardening where plants, usually fruit trees, are trained to grow flat against a wall or support structure. This not only creates a visually appealing display, but also maximizes space in smaller gardens. Companion planting, on the other hand, involves planting different species of plants together to maximize their growth potential and provide mutual benefits. This article explores whether there are any specific pruning techniques for espaliered plants in a companion planting setup.
Espaliered Plants
Espaliered plants require regular pruning to maintain their desired shape and promote healthy growth. The aim is to create a flat, lattice-like pattern with the branches by training them along horizontal wires or trellises. Pruning is typically done during winter or early spring before the growing season begins. The specific pruning techniques for espaliered plants depend on the desired shape and the type of plant being trained.
Pruning Techniques
1. Spur Pruning: This technique involves cutting back the branches to short spurs with two or three buds. It encourages the growth of fruiting spurs along the main branches, promoting fruit production.
2. Pinching: Pinching refers to removing the soft tips of the branches to encourage lateral growth and branching. This helps create a dense and compact plant structure.
3. Rubbing Off: Rubbing off involves removing any unwanted shoots or buds that appear along the main branches or trunk. This helps maintain the desired shape and prevents overcrowding.
4. Thinning: Thinning is the process of selectively removing excess branches to improve air circulation and sunlight penetration. This reduces the risk of diseases and ensures even distribution of nutrients.
Companion Planting
Companion planting is a popular technique used in gardening to enhance plant growth, improve pest control, and increase overall productivity. By planting certain species together, plants can benefit from each other in various ways, such as repelling pests, attracting beneficial insects, enriching the soil, and providing shade or support.
Benefits of Companion Planting
1. Pest Control: Certain plant combinations help repel pests and attract beneficial insects, creating a natural pest control system. For example, planting marigolds with vegetables can deter nematodes, while interplanting herbs like basil and rosemary can repel aphids.
2. Soil Enrichment: Some plants have the ability to fix nitrogen in the soil, which improves nutrient availability for neighboring plants. For instance, legumes like beans and peas can form a symbiotic relationship with nitrogen-fixing bacteria, benefiting surrounding plants.
3. Shade and Support: Tall plants can provide shade to smaller, shade-loving plants, protecting them from excessive heat and sunlight. Additionally, climbing plants, such as beans or cucumbers, can be grown alongside trellised espaliered fruit trees, utilizing the vertical space and providing support.
Pruning Techniques for Espaliered Plants in Companion Planting
When it comes to companion planting with espaliered plants, the same basic pruning techniques apply. However, there are a few additional considerations to keep in mind:
1. Shape and Spacing
When selecting companion plants for your espaliered fruit trees, consider their mature size and growth habit. Make sure to choose plants that won't compete for space or outgrow the designated area for the espalier. Proper spacing is important to prevent overcrowding, which can lead to decreased air circulation and increased risk of diseases.
2. Sunlight Requirements
Companion plants should have similar sunlight requirements to the espaliered fruit trees. If the companion plants need full sun, ensure they won't shade the espaliered tree and hinder its growth. On the other hand, if the companion plants prefer shade, make sure they won't be deprived of sunlight by the dense foliage of the espalier.
3. Compatibility
Certain plants have natural compatibility with each other due to their growth patterns and root systems. Choose companion plants that complement the espaliered fruit trees and won't compete for nutrients or space. For example, planting shallow-rooted lettuce or herbs near the surface won't interfere with the deeper root system of the fruit tree.
4. Pruning Timing
It is essential to synchronize the pruning schedule of the companion plants with the espaliered fruit trees. This allows for efficient pruning and prevents accidental damage to either plant. Plan your pruning activities during the dormant period of the fruit trees, as this is the ideal time to shape and train branches without inhibiting growth.
5. Pruning Techniques
Apply the same pruning techniques mentioned earlier to both the espaliered fruit trees and companion plants. Pinching, thinning, spur pruning, and rubbing off unwanted shoots should be performed to ensure proper growth and shape for both plant types. However, be cautious not to over-prune or damage the plants during the process.
Conclusion
Pruning techniques for espaliered plants in a companion planting setup largely remain the same as those used for regular espaliered plants. The key is to consider the specific requirements and compatibility of the companion plants with the espaliered fruit trees. By properly pruning and selecting companion plants that complement each other, you can create a harmonious and productive garden setup.
