USDA hardiness zones present
Agriculture is one of Indiana's foundational industries, with farmland covering the majority of the state and family operations still forming the backbone of rural communities. The state sits within the productive Corn Belt of the Midwest, and its deep, fertile soils support both large-scale commodity farming and a wide range of specialty and home gardening. For growers and gardeners, Indiana offers a long, warm growing season and reliable summer rainfall that suit a broad mix of crops.
Farming in Indiana
Corn and soybeans are Indiana's leading crops by far, planted across millions of acres each year and driving much of the state's farm economy. Other important field crops include winter wheat, hay, and popcorn, along with specialty crops such as tomatoes for processing, melons, mint, and pumpkins. On the livestock side, Indiana is a major producer of hogs, table eggs and chickens, turkeys, and ducks, and it also supports dairy and beef cattle herds. The typical Indiana farm blends large grain operations in the flatter central and northern regions with more diverse livestock and specialty production in the rolling south.
Climate and growing conditions
Indiana has a humid continental climate with warm, often humid summers and cold winters, along with fairly even rainfall through the growing season. The frost-free growing season generally runs from roughly 150 days in the north to around 180 to 190 days in the far south. USDA hardiness zones range from about 5b in the northern counties to 6b across much of the south, with the southernmost areas sometimes reaching zone 7a.
