Pomegranate trees may grow as high as 30 feet, but most reach no more than 16 feet, making them ideal for planting in gardens and smaller yards. Pomegranate trees produce attractive flowers and edible fruit and require little care to thrive. Pomegranates planted from seed do not come true to variety, which means no guarantee of fruit appearance, size or taste. The trees, however, are simple to grow from seed collected from eaten fruit and require no rest period for germination. The pomegranate prefers a mild-temperate to subtropical climate and can be severely injured by temperatures below 12 F.
Fill a potting container with moist potting soil. Lay the pomegranate seeds on top of the soil and press down. The seeds should rest just below the soil surface.
Place a heating pad beneath the pot, if necessary, to obtain the proper germinating temperatures. Germination takes approximately one month and requires fluctuating temperatures of 65 to 70 degrees Fahrenheit at night and 84 to 88 degrees during the day.
Transplant your pomegranate seedling to a warm, sunny location in spring. If you intend to have multiple trees, plant them at least 6 feet apart. The soil should be well-draining.
Dig a hole twice the size of your planting container. After breaking up the soil around your seedling, place the entire root system into the hole. Fill in the space around your pomegranate, making certain to get rid of any air pockets.
Water young pomegranates immediately after planting and then every few days for the first two to three weeks. Gradually reduce watering frequency to once every week. Established pomegranates can withstand considerable drought, but too little water will negatively affect fruit production.
Fertilize young trees in early winter and early spring using an 8-8-8 fertilizer. Young trees typically require about 2 pounds of fertilizer, with established trees needing twice that amount.
Prune your pomegranate when it reaches 2 feet tall. Allow four shoots to develop about 1 to 2 feet from the ground. Because fruit develops on the tips of new growth, prune the branches once each year to encourage fruit production. Remove suckers and damaged or disease branches annually.
