Pruning tea bushes

My family plant tea and rubber for living. We are having heavy rain these days. So before heavy rain starts tea pruning commenced and finished. To prune a tea bush a very sharp knife specially crafted for this purpose is used. Pruning is done for mainly to expand the bush to create space for more new branches to be shooting up and maintain the height of the bush manageable when picking tea leaves. Following image shows bushes pruned last year.

In pruning all branches are cut leaving only one branch unless the bush will be dead without leaves. After new shoots come up the left branches also get pruned. These are newly pruned bushes. Look at sharp edges of cut branches. Cuts must be clean and sharp. Cut branches are left there to dry up and will be cleaned after rains.
