This type of pruning is not always needed, but it’s recommended if you want to avoid your plant looking leggy and to achieve a bushier, fuller plant.
The goal is to remove about 1/3 of a branch, and focus on branches that looks leggy and woody. You can remove even more if you think it’s needed.
THIS IS HOW YOU DO A CUT BACK:
Use a clean pair of scissors
Measure from the top of a branch, and remove 1/3 of it
Make the cut just over a node of leaves
Repeat on all branches that look leggy or woody
