Sugar cane is a warm temperate to tropical climate plant. It requires at least 24 inches of rainfall per year minimum falling over several months. It does not tolerate severe frosts so all sugarcane grows between 33 degrees north (about the AR and LA border) and 33 degrees south latitudes. Sugar beets grow in a cool temperate climate within a narrow soil type. Beets are grown in CA, CO, UT, MI, MT, ID and other northern states.
