Tomatoes can be grown successfully in containers and perform best in pots at least 20-25cm in diameter. Several tomato varieties are recommended for containers, including 'Gardeners Delight' and 'Sungold' which produce small fruits quickly, and 'Harbinger' which has large fruits and great flavor. Tomatoes should be started from seed indoors in early spring and moved outside gradually after the last frost. They require regular watering, support, protection from cold, and occasional feeding for high yields of flavorful fruits over the summer months.
