People who want to grow a red banana bush can do so if they live in a tropical to semi-tropical area, roughly between USDA zones eight and 11. Bananas also have very interesting foliage which can make them nice ornamentals in addition to fruit producers; it generally takes around nine months for a banana bush to mature and produce fruit. Well-drained soil, full sun, and protection from the wind are critical for a banana bush. Once the fruit matures, the bush should be lopped back to the ground, allowing a new bush to grow and produce fruit.
