The dwarf pomegranate, like its full-sized cousin, is a subtropical tree native to Asia and the Mediterranean. It has dark green leaves, orange trumpet-shaped flowers and orange-red fruit--which in the case of the dwarf pomegranate is purely ornamental. This makes it an ideal candidate for bonsai. Trees grow best in full sun and should be brought indoors in areas that get wintertime frost. Trimming the trees ensures healthy foliage growth as well as flowering and fruiting.
Prune only after flowering and fruiting has ended. You don't want to risk cutting off new growth. Winter is the best season to prune your dwarf pomegranate.
Check the crown for suckers and trim with pruning shears. Suckers drain nutrients from the plant and stymie healthy growth. Fortunately dwarf pomegranates aren't as likely to develop suckers as their full-size peers, but they do spring up occasionally--and when they do, they must be promptly snipped off.
Trim tips of branches, shaping the tree however you desire. Trimming the tips of branches encourages thicker, denser foliage.
Cut back branches that have fruited for several years in a row to just one or two sets of leaves. Branches that carried flowers and fruits for several years tend to become fatigued, and should be removed to let new branches grow in their stead.
