Pruning and transplanting ornamental and shade trees : A dissertation for Diploma in Park and Recreation Administration [Lincoln College]

Abstract

The process of pruning is usually an invigorating one since it allows more nourishment to go to the remaining parts. It is not devitalising unless carried to excess, due to the loss of potential food production by the leaves. It should be remembered that leaves are the production units of the trees; by using light, carbon dioxide, water and minerals from the soil, through the process of photosynthesis, they produce starches and sugars. It is easy to see, therefore, why the removal of an excessive quantity of live wood and leaves is harmful.
