Pomegranates may be one of the friendliest fruit trees to grow in the home garden, as long as you live in a suitable environment. They are ancient trees that produce lovely ornamental flowers and delicious fruit prized for their health benefits. They usually grow to only 10-20 feet high and can even thrive in large pots.
Regular pomegranates will grow in large pots (at least 10 gallons), and still produce fruit, but they need to be kept well pruned in order to survive. You may be able to grow container pomegranates in cooler areas too, if you can bring them indoors when temperatures dip below 40° F.
