A tree will attempt to fill any gaps in its canopy with branches and leaves as it grows. Trees love light and are what is called ‘phototrophic’ which basically means they grow towards the light.
Trees also develop in balance with their surroundings and according to the space available to them as well as many other factors such as the typical weather conditions they are faced with, the type of soil they grow in and the amount of water available to them. Trees are basically woody plants and day by day they try to grow towards the sunlight. Leaves on a tree capture sunlight and convert it into sugars which the tree stores throughout its structure.
Trees react in all kinds of different ways to pruning. The correct way to prune a tree varies considerably from one species to the next.
Deciding to remove a tree has to be based upon a whole range of factors and in some instances certain trees and areas have rules and regulations that you must follow.
Factors to consider before removing a tree are; the species of the tree, its position, the absence or presence of disease, the trees surrounding it, any previous tree surgery and the time of year to name but a few. You should really consider exactly what your motives are before removing any trees just so that we can all work on making sure we are not destroying healthy trees without a valid reason to do so.
Tree surgery is a difficult profession to master and bad, heavy-handed tree surgery on some species of trees can actually lead to thicker, more dense regrowth which in turn creates more shade & more leaves which is the one thing that many customers do not want.
