Growing Requirements for Pomegranate Trees

The pomegranate tree is a resilient variety that requires little care. Homeowners appreciate its ornamental flowers and production of juicy, tart fruit. Typically found in drier areas of California and Arizona, the pomegranate tree can be a successful grower in backyards as far north as Washington, D.C. Pomegranate trees easily adapt to container living, making them a superb choice for a patio or greenhouse.

Light

Pomegranate trees are natural to tropical and subtropical areas and prefer a location in full sun. They will fruit and flower in warm, partial sun, but the fruit tends to be small and sparse from such trees.

Temperature

Pomegranate trees are best suited for areas offering hot summers and cool winters. This allows the deciduous tree to enter its natural growth and dormancy periods. Some species can tolerate temperatures as low as 10 degrees. The bark is susceptible to frost damage and should be protected in freezing temperatures.

Soil

Deep loam is the optimal soil for planting a pomegranate tree but the trees are tolerant of most well-draining types including rocky or sandy soil. A slightly acidic to neutral pH, is ideal but the tree can grow well in a mild alkaline. It's recommended you remove competing vegetation within 1 to 2 feet around the tree.

Water

The pomegranate tree prefers to be semi-dry. Deep soak every two to four weeks during the dry season. Container plants can go 7 to 10 days between watering. Mature, established pomegranate trees can endure drought lasting months; however, they will not produce fruit. If fruit shows signs of splitting it's a sign your tree needs water.

Fertilizer

Established trees can thrive without fertilizer but will appreciate a layer of compost or mulch around the base. New trees should receive 2 to 4 ounces of ammonium sulfate or other nitrogen. Apply in the spring before the tree blooms.

Pruning

The pomegranate tree is naturally a shrub and tends to produce sprouts and suckers. These should be removed as soon as they appear to train the tree to grow into a single trunk. Dead and damaged branches should be removed in late winter when the tree is dormant. Prune sparingly to encourage the production of a quality fruit.

Problems

Fungus is the most serious threat to the health of a pomegranate tree. It results in splitting fruit and premature loss of leaves. Apply a copper fungicide during the late spring through summer to treat.
