Crown thinning is the removal of a portion of smaller branches, usually at the outer crown, to produce a uniform density of foliage around an evenly spaced branch structure. Crown thinning does not alter the overall size or shape of the tree but will increase the amount of light entering the canopy and ground below. Crown thinning will also reduce the risk of storm damage by allowing wind to pass through the canopy.
If you find that your tree has outgrown its environment it may need a crown reduction to reduce the overall size of the tree. The crown is reduced and thinned in all directions where appropriate depending on your particular trees species, age and condition to leave a healthy and balanced crown structure. Often reductions are specified as a percentage but more recently is referred to as ‘metres removed’. Our tree surgeon will advise you on a suitable size reduction for your trees.
Crown raising is simply removing branches from the bottom of the crown of a tree to provide clearance for pedestrians, vehicles, buildings or lines of site. If your tree crown overhangs a public footpath you may be asked by your local authority to raise the crown for safety reasons. The height is achieved by the removal of whole branches or removing the parts of branches which extend below the desired height. The branches are normally not lifted to more than one third of the tree’s total height. Crown lifting is an effective method of increasing light to the area your tree occupies.
