Crown reduction reduces a tree’s crown and is used to reduce the height and/or spread of the crown of a tree by the removal of the ends of branches while still maintaining its natural shape. This technique can be used to: reduce wind resistance, to reduce water up-take, to control the size of a tree in a restricted environment or to allow more light through. This method is not to be confused with topping, which is detrimental to the trees health. Crown reduction carried out correctly involves cutting branches back to a growing point, an area that will heal and continue the life of your tree. Topping is usually random cuts, which soon get infected, and in some cases promotes tree growth, which is not the goal.
Crown lifting is the selective removal of the lower branches of a trees crown to increase the distance between the base of the canopy and ground level. This type of pruning should, if possible be carried out before a tree reaches maturity in order to avoid large wounds.
This involves the selective removal of some secondary branch and stem growth to create a less dense crown. Crown thinning is sometimes recommended to increase light, however, the European Standard advises a maximum of 15%. if there are complaints about a tree blocking the light, but is often unsuccessful because the amount of branch wood we remove without harming the tree is minimal. Work can also be carried out to create a more balanced crown as the weight on the limbs is lifted and the tree’s natural shape returned.
Dead wooding is the safe removal of any the dead wood from the tree. This is to stop the hazard of them falling on to buildings, vehicles or the public.
This involves removing dead or diseased branches. Crown cleaning will only be carried out where there is a real possibility of falling branches causing accidents or injury, or if diseased branches threaten the tree’s health. Dead wood has immense ecological value and is not normally removed from trees which are away from very public areas eg quiet areas of parks or woodlands.
