One of the recommendations Tendring Tree Surgery may make is a crown reduction on your tree. This is a pruning technique that should be carried out by a qualified tree surgeon.

What is a crown reduction and why would it be needed?

A crown reduction is a type of tree pruning to remove branches from the tree in order to reduce the size or spread of a tree, whilst maintaining the main framework of the tree’s crown. It can be carried out to:

  • Improve light levels

  • Reduce the risk of falling branches

  • Clear space for buildings or other structures

  • Maintain the tree's health

At Tendring Tree Surgery, we carry out our crown reductions to the British Standard 3998:2010. This standard provides guidance on the best practices for tree work.

By ensuring the work to your tree is carried out by qualified tree surgeons like us at Tendring Tree Surgery, who have been trained to follow the best practices for tree work, the tree is less likely to be damaged during the reduction process and is more likely to recover quickly.

How can British Standard crown reductions help save money in the long run?

British Standards tree reductions can help to save you money in the long run by reducing the need for future tree work. For example, if a tree is reduced to maintain its health, it is less likely to develop problems that would require more expensive tree work in the future.

Here are some more specific examples of how British Standards tree reductions can save you money in the long run:

  • Reduced risk of tree failure: British Standards tree reductions can help to reduce the risk of tree failure by removing dead, diseased, or damaged branches. This can help to prevent costly damage to property and infrastructure.

  • Improved tree health: British Standards tree reductions can help to improve the tree's health by removing excess branches and allowing more light and air to reach the tree's crown. This can help to reduce the need for future tree work, such as crown thinning or deadwood removal.

  • Reduced maintenance costs: British Standards tree reductions can help to reduce the cost of tree maintenance by making it easier to access the tree and to carry out routine tasks such as pruning in the future.

If you are considering having a tree reduced, it is important to choose a qualified tree surgeon who is familiar with British Standards 3998:2010.

What happens if a tree is not reduced properly?

If a tree is not reduced properly to British Standards, it can have a number of negative consequences. These include:

  • The tree may be weakened and more susceptible to disease and pests. This is because improper reduction can damage the tree's bark and cambium, which are the layers of tissue that are responsible for transporting water and nutrients throughout the tree.

  • The tree may become unbalanced and more likely to fall over. This is because improper reduction can remove too much weight from one side of the tree, or it can create weak points in the tree's structure. This can pose a danger to property and people.

  • The tree's appearance may be spoiled. Improper reduction can leave the tree with unsightly scars and stubs.

  • The tree can put out reaction growth; a stress response. This can result in future work needing to be carried out at shorter intervals.

A crown reduction is a complex process, and it is important to have it carried out by a qualified and experienced arborist.
