Hi this is Peggy, Here are the times and how to prune calamondins. I hope this helps you. Prune the calamondin for size and shape control if necessary. Act after the harvest. Trim each of the highest branches at a lateral branch at least one-third the diameter of the cut branch. Limit the tree's height to make it easy to harvest fruit but never take out more than 25 percent of the tree's canopy.
