Pomegranate
By Tami Reece UCCE Master Gardener
Common name of plant: Pomegranate
Scientific name: Punica granatum
Planting area: Sunset zone 7-10
Size: 12 to 20 feet height and 12 to 15 feet width
Bloom Season: flowers bloom late May to June; fruit ripens September to October.
Exposure: minimum 6 hours full sun.
Pruning needs: prune during dormancy to remove crossing branches and to
open up the center to allow light and air to reach blooms.
Water needs: drought tolerant; however, for good fruit production, irrigate 5 to 6 inches every 10 days.
Snapshot: Pomegranates grow naturally as a shrub but can be pruned into small trees. Pomegranates are deciduous in the interior and desert areas. Along the coast, they may lose only a portion of their leaves in the winter. Pomegranates are cold hardy down to 10F when dormant and must be protected from frost in late fall before full dormancy or early spring when it begins to bud. It is adaptable to different soil types, growing best in deep loam, though it will tolerate sandy and clay soils. In wetter areas, they are prone to root decay from fungal diseases.
Pomegranates can be grown from seed but are easier to propagate by cuttings.
The pomegranate fruit is red-purple in color. The husk has two parts: an outer, hard pericarp, and an inner, spongy mesocarp, which comprises the fruit's inner wall where the arils attach. Membranes of the mesocarp are organized as nonsymmetrical chambers that contain richly red colored arils. The number of arils in a pomegranate varies from 200 to almost 1,400. Pomegranate arils are delicious used in savory recipes, baked goods, sprinkled on salads, pressed into juice, or simply eaten fresh, straight from the fruit.
A good variety to add to your garden is the “Wonderful” pomegranate. It produces beautiful, sweet, delicious ruby red arils with the fruit growing to the size of grapefruits. If you are looking for a mid-size tree to add color and beauty to your landscape and fruit to your table, try planting a low maintenance drought tolerant pomegranate tree!
