It is recommended that trees are worked on after leaf fall and before bud burst. This however is not true for all species so we would prefer to look at each tree individually and give you a written report and recommendation for timing the necessary work. Some examples of trees requiring work at other times are Cherry, Plum and related trees (Prunus species). These should be pruned soon after flowering to reduce the risk of bacterial infection. Maple and Birch should not be pruned in the spring to avoid ‘bleeding’ (exuding sap), which although not considered damaging can be unsightly while Magnolia and Walnut should only be pruned in high summer. Most common species of hedges can be pruned any time of the year but again we would confirm this after inspection and always consider the environmental impact in terms of nesting birds etc before commencing.

As a rule of thumb, a tree’s root system extends as far underground as its canopy does over ground. This can be distorted by regular or severe pruning, but it is generally possible to manage a tree’s root system underground by regularly pruning or reducing the canopy above ground because a tree does not need to expend energy developing its root system if it does not have to support a large canopy above ground.
