What planting zone range is Indiana

For the unacquainted, a planting zone refers to a geographical area in which certain categories of plant life can survive and thrive, depending on average climate conditions, particularly minimum average temperature.

Indiana has a relatively small range of planting zones, with the state including only zones 5b through 6b. Gardeners can check the interactive Indiana USDA hardiness zone map to know which planting zone they live in.

Since a region’s climate is another factor that impacts the survival of many plants, gardeners need to understand the climate zone they live in. Indiana has what is called a humid continental climate sandwiched between small snippets of humid subtropical climate. A large part of the state sees wet, warm summers, cold winters, and fairly evenly distributed rainfall throughout the year, with the southern region receiving more rainfall than other parts.

In the spring, there are active thunderstorms and tornadoes.

What planting zone is North Indiana

Based on the 2012 revision of the USDA hardiness zone map, much of Northern Indiana is in zone 5b, with a very small section of zone 6 in the northeastern corner.

For gardeners living in this area, first frost dates do not begin until October, and one average range between October 1 and October 10. On the other hand, the last frost is typical from May 21 to May 31. Because this information is based on past climatic data, beware that there is a chance of frost occurring outside these dates.

What planting zone is South Indiana

Unlike the entire northern part with a humid continental climate, the very bottom of Indiana state enjoys a humid subtropical climate. As such, it registers a bit warmer and sits in planting 6b, which normally expects minimum temperatures of 0 to -5 degrees Fahrenheit.

For the purpose of proper timing and selecting plants to grow, the first frost usually occurs between October 11 and October 20, then lasts until somewhere between May 1 and May 10. With these dates in mind, gardeners can easily plan when and what to plant in southern Indiana and also harvest before frosts cover the produce.

For more accurate first dates, keep an eye on local weather.
