Crown Thinning in Warrington


Crown thinning is an advanced pruning operation normally carried out on hardwood trees by our professional tree surgeons in Warrington. It involves removing dead and dying branches, branches which are rubbing together and general weaken the structure of the tree. We also offer a crown reduction and a crown lifting service. Crown treatment is essential in fruit tree pruning.

The benefits of crown thinning are:

To improve the trees structure and form
To keep the tree healthy and free of problems
To keep fruit trees productive and flourishing
To allow more light to penetrate through the canopy
To keep the tree free from fungal infection and disease
To reduce the effect of high winds on the tree
To prevent potential storm damage

I only scored Grant Morris Tree Services 10 in all fields because it wouldn’t let me score any higher. To say that we are delighted with the work carried out would be an understatement and I can’t recommend Grant Morris Tree Services highly enough. I chose them because of the work they carried out on my neighbours trees, they’re also working on my next door but one neighbours trees as well. I will use no one else apart from Grant Morris Tree Services to carry out tree work in my garden in the future

Mr Roberts,

I can’t fault Grant Morris Tree Services , from the first visit to completing the work Henri was very helpful, extremely informative and professional, the work was done with skill and care on our 500 year old horse chestnut and the clean up was thorough, you wouldn’t know they had been. I would highly recommend Grant Morris Tree Services .

Mrs Morris,

I was very happy with the work done. They were quick, accurate and thoughtful. They cleared up after themselves, so much so that the garden was much more tidy than when they arrived! They worked very hard in extremely humid conditions but didn’t even stop for a break. I would be very happy to use Grant Morris Tree Services again and I thought their rates were very competitive

Mrs Andrew,

More Information On Crown Thinning

Our experienced team of Warrington tree surgeons will will ensure that the weaker branches of the tree are removed during crown thinning. We look for for tree branches which form acute V-shaped connections to the trunk of the tree and other branches. Such V-shaped connections form a bark wedge. These bark wedges will weaken the connection presenting a serious hazard to public safety during storms and high winds. The removal of a V shaped branch connection will cause the remaining branch to grow stronger. Branches and multiple tree trunks on the same tree which form a U shaped connection are generally considered to strong and should not be thinned.

When crown thinning our tree surgeons in Warrington ensure that any branches growing off another are less than 75% of the diameter of the root branch at the point of attachment. When crown thinning we ensure that we do not leave a collection of smaller branches, shoots and leaves at the very end of the branch ( known as lion tails). Lions tails will lead to epicormic sprouting and will eventually lead to uneven weight distribution in the branch, causing it to break off.

As a general rule, when crown thinning in Warrington we never remove more than 25%-30% of the living crown. If more needs to be removed this should be done in successive years to ensure the health of the tree.
