Proper pruning of trees ensures their strong growth and improves their health. It also ensures that the branches do not obstruct or cause damage to life or property. Pruning gives trees an opportunity to grow new green and healthy branches. It also makes them well structured.
Trees should be pruned in winter. It is their dormant period as trees shed their leaves. During the Spring or Summer season, if you prune trees, it might negatively impact the plant or tree.
