Cacao (Theobroma cacao L.) is native to tropical areas in Mexico, and Central and South America. The Aztecs and Mayas widely cultivated cacao for ceremonial as well as culinary purposes. Please see Aztec Gardens for more information on the pre-Hispanic foods of the Americas.
Most people interested in growing cacao in the United States have to do so in a greenhouse. However, it is suitable for growing in USDA zones 9B—11. Plant the tree in partial shade. Make sure your soil is moist and high in organic materials. Adding compost will also insure that your soil drains well. Cacao requires frequent watering. Your tree should grow to around 20 feet or more when mature.
