Crown Thinning

Crown Thinning

There are times when the canopy of the tree becomes too dense and, thereby blocking out the light. This can damage other plants, grassed areas and trees, and also plunge buildings, and gardens into darkness. Crown Thinning is the method of allowing more light through the crown without altering the shape or size as you might with a Crown Reduction. We remove selective branches from within the canopy to allow a balanced amount of light to penetrate through the canopy.

The method for Crown Thinning is the selective removal of branches throughout the canopy. Tree Surgeons will usually set the percentage of how much of the crown will be thinned by. Your Tree Surgeon shouldn’t reduce more than 30% of the crown overall when Crown Thinning the tree.

Your Tree Surgeon will usually proceed by removing dead, dying and crossed branches first and then proceed to select further branches to complete the desired result.

If you need a crown thinning, our surgeons are available to help. Please call us on 01204 592850 or email us at info@arieltreecare.com.

Crown Thinning FAQs

What is crown thinning, and how is it performed?

Crown thinning is the selective removal of branches within a tree’s canopy to allow more light to pass through without changing the tree’s overall shape or size. This helps prevent damage to nearby plants, lawns, and buildings caused by excess shade. A tree surgeon typically begins by removing dead, dying, or crossed branches, then carefully selects additional branches to thin the crown evenly. No more than 30% of the crown should be removed during the process to maintain the tree’s health and structure.

In many cases, yes. Early diagnosis and timely treatment can help restore a tree’s health. If you notice signs of stress or illness, we recommend booking an inspection as soon as possible.

How do I know if my tree is diseased or has pests?

Look for symptoms like:

  • Leaf discoloration or wilting
  • Fungal growths or cankers on the bark
  • Holes.

If something doesn’t look right, it’s best to call a professional to assess the tree and recommend treatment.

What if there are birds nesting?

Work is best considered after any bird activity has ceased as we are legally and morally obliged to stop work until the young have flown the nest which can be over 6 weeks.

When is the best time to prune trees?

Timing depends on the species and the purpose of pruning. It is advisable to seek professional help from a tree surgeon who can advise on the best schedule for your specific trees.

What is tree surgery, and what does a tree surgeon actually do?

Tree surgery is a specialist service within arboriculture that involves the care, maintenance, and management of trees. A tree surgeon (or arborist) is highly trained to handle tree pruning, maintenance and removal. They are also equipped to handle emergency situations and offer expert advice on all aspects of tree related matters.

My neighbour’s tree is blocking sunlight to my property – what can I do?

You are legally allowed to prune branches that overhang your boundary, but only up to the property line – you must not cut anything beyond it. Open communication with your neighbour is always advised before carrying out any work.

What if I live in a conservation area?

Again we have to seek permission to do work in the area from the local planning authority but we can do that for you. This done via a Notice of Intention application. A decision is then given by the local authority within 6 weeks.

How do I know if a tree is under a Tree Preservation Order?

Many councils provide interactive maps on their websites that you can check yourself or alternatively we can do that for you.

If my tree is protected by a TPO (Tree Preservation Order), can I still carry out any work on it?

Yes – but there are strict conditions:

  1. If your tree is diseased or damaged and poses a risk (e.g. potential limb failure), you can apply for emergency work permission with seven days notice to the local council’s Tree Officer. This request should be backed by a tree surgeon’s report – which we can prepare for you.
  2. For routine or planned work on a protected tree, you’ll need to apply for permission through the local planning authority. Again, a detailed tree report is beneficial and we’re happy to submit this on your behalf. The application process can take up to 8-12 weeks. If granted, the permission remains valid for 2 years.
