Saveh pomegranates, which originated in the Saveh province of Iran, are the most cold-tolerant of the pomegranate family and produce extremely large and flavorful fruit. They can be grown in hardiness zones 7 through 11, but grow best in the drier areas of California and Arizona. The Saveh variety has been known to grow in zone 6, but must be protected from the extreme cold temperatures of winter. Once established in a warm area, the Saveh pomegranate is extremely hardy and drought tolerant.
Take several cuttings of last year's growth. Cuttings should be taken in late winter or very early spring while the tree is still dormant. Make your cutting just below a leaf node. Cuttings should be taken from the tip of a branch and should be approximately six to nine inches long.
Fill a growing pot with damp potting soil and shove the cut end of the cutting, with the leaf node, into the soil, approximately three inches deep. Place the pot in a sunny and warm location and keep it relatively warm (approximately 70 to 75 degrees Fahrenheit during the day, no lower than 65 degrees Fahrenheit at night). Keep the soil damp, but not soggy.
Watch for leaf growth after four to six weeks. Saveh pomegranates root easily, so most of your cuttings should take root.
Plant your cuttings outdoors when they are eight to 10 weeks old. Dig a hole twice as large as the root ball of your cuttings and mix 50 percent potting soil with the garden soil. Gently press the soil around the roots, being careful not to break them. Water well and keep the soil damp, but not soggy, for at least eight weeks, until the cutting shows signs of growth. Choose a warm and sunny location that can be protected from harsh winter temperatures. Plant trees 12 to 16 feet apart.
Apply an inch of organic manure if leaves turn yellow, but keep in mind that pomegranates do not require much fertilizer.
