Pollarding is a tree management technique that has been used for centuries to promote the growth of new shoots and to maintain the size of trees. It involves the regular pruning of the upper branches of a tree back to the trunk, creating a distinctive "knuckle" at the top of the tree.
One of the primary benefits of pollarding is that it can help to extend the life of a tree. By limiting the size of the tree and promoting the growth of new shoots, pollarding can prevent the tree from becoming too heavy and causing damage to its structure. This is particularly important in urban areas, where large trees can pose a risk to nearby buildings and infrastructure.
Pollarding can also be used to control the growth of trees in areas with limited space, such as along roads or in small gardens. By regularly pruning the upper branches of the tree, it is possible to maintain its size and shape while still allowing it to grow.
Another benefit of pollarding is that it can help to increase the aesthetic appeal of a tree. The knuckles that are formed at the top of the tree can create a unique and striking silhouette, making the tree an attractive feature in any landscape.
Despite its benefits, pollarding is not suitable for all types of trees. It is generally only recommended for fast-growing species such as willows, poplars, and certain types of oak. Additionally, pollarding requires regular maintenance and pruning, which can be costly and time-consuming.
Overall, pollarding is a valuable tool in the management of trees in urban and suburban environments. By promoting the growth of new shoots and limiting the size of the tree, it can help to extend its lifespan, control its growth, and enhance its aesthetic appeal. If you are considering pollarding for your trees, be sure to consult with a qualified arborist to determine if it is a suitable technique for your specific species of tree.
While pollarding is a useful technique for managing the growth of certain species of trees, it is important to note that it should not be confused with topping, which is a practice that involves removing large branches or even the tops of mature trees. Topping is a poor management practice that can severely damage trees and reduce their lifespan.
Unlike topping, pollarding is a more selective form of pruning that involves removing only the upper branches of the tree. By leaving the lower branches intact, the tree is able to continue photosynthesizing and producing food for itself, which is essential for its overall health and longevity.
In contrast, topping can cause a significant amount of stress to the tree and can even lead to its death. When large branches or the top of a tree are removed, it can disrupt the tree's ability to transport water and nutrients to its leaves and can also expose the tree to diseases and pests.
Furthermore, topping often results in the rapid growth of new shoots that are poorly attached to the tree and are more susceptible to breaking off during wind or storm events. This can create a hazard for nearby buildings, people, and other property.
Overall, it is important to understand the differences between pollarding and topping when managing the growth of trees. While pollarding can be a useful tool in promoting new growth and extending the lifespan of certain species of trees, topping should be avoided at all costs as it can cause severe damage and reduce the health and longevity of trees. Consulting with a qualified arborist is recommended to determine the best management practices for your specific trees.
