Prune very young pomegranate trees to establish their ultimate form and structural strength. The trees can be trained to a single-stem form or allowed to grow multiple stems, as they do naturally.
At planting time, select a strong, single stem or five to six stems, depending on your preference for a pomegranate's form. Remove all other stems, and cut the tree back to 24 to 30 inches in height. This task stimulates branching and side shoots that ultimately benefit tree health, productivity and ease of harvest.
Pomegranate trees sucker heavily, growing abundant new stems from their bases. Remove all suckers as they rise from the ground throughout the growing season.
