Pruning > Crown Thinning

Crown thinning is the removal of a small portion of secondary live branches throughout the crown to create a less dense crown.

crown thinning

Crown thinning is sometimes recommended if there are complaints about a tree blocking the light, it may be used to allow additional light to pass through the tree, reduce wind resistance, or to reduce the weight of heavy branches. The amount of branch wood we remove without harming the tree is minimal – the European Standard advises a maximum of 15%. Often 5% or 10% is sufficient. Thinning should not exceed 15%. It should be aimed at producing a uniform density of foliage around an evenly spaced branch structure. It is usually confined to broad-leafed species. Crown thinning includes crown cleaning and does not influence the size or shape of the tree. Crown thinning can enhance a tree’s appearance by creating a more visually balanced crown, and we will do this work where necessary. In some species however, over-thinning will stimulate unwanted formation of sprouts.
