Horticultural Tree Training: An Illustrated Guide115

Horticultural tree training is the art of manipulating the growth and shape of trees to improve their health, productivity, and aesthetics. By understanding the principles of tree growth and using a variety of techniques, gardeners can train their trees to achieve specific goals, such as increasing fruit production, creating shade, or improving the overall appearance of their landscape.

Principles of Tree Growth

Before you begin training your trees, it is important to understand the basic principles of tree growth. Trees grow in response to environmental cues, such as light, water, and nutrients. The direction of growth is determined by the location of the growth hormone, auxin, which is concentrated in the tips of branches and roots. When a tree is exposed to more light on one side than the other, the auxin will accumulate on the shaded side, causing the branches to bend towards the light.

Tree Training Techniques

There are a variety of tree training techniques that can be used to achieve specific goals. Some of the most common techniques include:
Pruning: Pruning is the selective removal of branches to control the growth and shape of a tree. Pruning can be used to increase fruit production, improve air circulation, and remove dead or diseased branches.
Grafting: Grafting is the process of joining two or more plants together to create a new plant. Grafting can be used to change the variety of a tree, improve disease resistance, or create a new cultivar.
Staking: Staking is the process of supporting a tree with stakes to prevent it from falling over. Staking is often used for young trees or trees that have been damaged by wind or storms.
Espaliering: Espaliering is the process of training a tree to grow in a flat, two-dimensional plane. Espaliering is often used to create decorative effects or to save space in small gardens.
Pollarding: Pollarding is the process of cutting back a tree's branches to a short trunk. Pollarding is often used to keep trees small in size or to create a specific shape.

Choosing the Right Training Technique

The best tree training technique for a particular tree will depend on the desired outcome. For example, if you want to increase fruit production, you would use a pruning technique that encourages the growth of new branches and spurs. If you want to create a decorative effect, you might use an espaliering technique. It is important to do your research and choose the right technique for your tree and your goals.

Training Trees for Specific Goals

Tree training can be used to achieve a variety of specific goals. Some of the most common goals include:
Increased fruit production: Pruning can be used to increase fruit production by encouraging the growth of new branches and spurs. By removing old, unproductive branches and crossing branches, you can create more space for new growth and improve the overall health of the tree.
Improved air circulation: Pruning can also be used to improve air circulation within a tree. By removing dead or diseased branches and thinning out dense areas of foliage, you can allow air to circulate more freely, which can help to prevent the spread of disease and pests.
Removal of dead or diseased branches: Dead or diseased branches can be a hazard to people and property. They can also provide a breeding ground for pests and diseases. By removing dead or diseased branches, you can improve the overall health and safety of your tree.
Create a decorative effect: Tree training can also be used to create a decorative effect. By espaliering a tree, you can create a living wall or screen. By pollarding a tree, you can create a unique and eye-catching focal point in your landscape.
Save space: Tree training can be used to save space in small gardens. By espaliering a tree, you can grow it in a flat, two-dimensional plane. By pollarding a tree, you can keep it small in size.

Conclusion

Tree training is a valuable skill that can be used to improve the health, productivity, and aesthetics of your trees. By understanding the principles of tree growth and using a variety of tree training techniques, you can achieve specific goals, such as increasing fruit production, creating shade, or improving the overall appearance of your landscape.
