Every spring, pomegranate trees produce big red blossoms that give way in the late summer to leathery fruit filled with hundreds of tiny, tart-sweet seeds. Native to the Middle East, the pomegranate tree will grow into a naturally rounded bush between 15 and 20 feet tall and equally wide if it's left unpruned.
Plant pomegranate trees in full sun, where they'll get at least eight hours of direct sunlight per day. In cooler zones, plant them against a west- or south-facing wall.
Mix plenty of compost into the soil to ensure good drainage.
Water well once or twice a week to encourage the tree to bear fruit.
Fertilize once a year with high-nitrogen, time-release fertilizer.
Prune mainly to remove dead limbs and suckers; otherwise, prune a bit to maintain a nice shape.
