What are the 4 planting zones in Indiana?

Indiana’s hardiness zones range from 5b in the north to 7a in the south.

1. Zone 5b

Zone 5b covers inland northwest Indiana, south of the Lake Michigan shore. With average annual minimum temperatures ranging from -15°F to -10°F (-26.1°C to -23.3°C), it represents the coldest region in the state. Cities in this zone include Crown Point, Lowell, Cedar Lake, DeMotte, Knox, and Winamac, plus Crawfordsville in west-central Indiana. The zone covers southern Lake, Porter, and La Porte counties and most of Newton, Jasper, Starke, and Pulaski counties; the lakeshore cities of Gary, Hammond, Valparaiso, and Michigan City are Zone 6a.

2. Zone 6a

Zone 6a covers most of northern and central Indiana, about 6 in 10 Indiana ZIP codes. This zone experiences average annual minimum temperatures between -10°F and -5°F (-23.3°C to -20.6°C). It stretches from the northeastern corner near Angola, westward through Fort Wayne and South Bend, and southward to the northern and eastern edges of Indianapolis and its suburbs Carmel and Fishers. Cities in this zone include Elkhart, Kokomo, Lafayette, Muncie, Terre Haute, and the Lake Michigan shore cities from Hammond and Gary to Michigan City.

3. Zone 6b

Zone 6b covers south-central, southwest, and southeast Indiana, about 1 in 4 Indiana ZIP codes. With average annual minimum temperatures ranging from -5°F to 0°F (-20.6°C to -17.8°C), this zone offers a slightly milder climate than 6a. It includes Bloomington, Columbus, Bedford, Jasper, Vincennes, and downtown, west, and south Indianapolis. The zone reaches the Ohio River in the southeast, at Lawrenceburg, Aurora, Rising Sun, Vevay, and Madison.

4. Zone 7a

The warmest zone in Indiana, 7a, covers the southwestern and south-central Ohio River valley. This zone experiences average annual minimum temperatures between 0°F and 5°F (-17.8°C to -15°C). It runs along the Ohio River from Mount Vernon and Evansville east to Tell City, Corydon, New Albany, and Jeffersonville, and reaches north to Charlestown and Sellersburg in Clark County and to Fort Branch and Oakland City in the southwest. Cities in this zone include Evansville, Newburgh, New Albany, Jeffersonville, and Clarksville. The milder temperatures in this zone allow for a wider range of plant varieties compared to the northern parts of the state.

Factors considered in creating Indiana’s new planting zones?

The USDA Plant Hardiness Zone Map for Indiana shows the average coldest winter night of each year over 30 years (1991–2020). The PRISM climate model behind the 2023 map also accounts for elevation, distance from Lake Michigan, and terrain.

Indiana Frost Dates

In Indiana, the typical last spring frost comes on April 28 and the first fall frost on October 15, from NOAA 1991–2020 weather-station records for 929 Indiana ZIP codes. Spring frosts end about 3 weeks earlier along the Ohio River (Zone 7a, April 10) than in northwest Indiana (Zone 5b, May 2). The table gives the median date for each Indiana subzone and the range that covers 8 of 10 ZIP codes; in 7 of 10 years, the frost comes before the spring date and after the fall date. The growing season is the number of days between the two dates. Frost dates for one garden come from its ZIP code: frost dates by ZIP code; town by town: frost dates of Indiana cities and towns.

Subzone	Last spring frost	First fall frost	Growing season
Zone 5b (45 ZIP codes)	May 2 (Apr 29–May 4)	Oct 11 (Oct 7–Oct 13)	162 days
Zone 6a (567 ZIP codes)	Apr 30 (Apr 22–May 4)	Oct 15 (Oct 9–Oct 20)	168 days
Zone 6b (226 ZIP codes)	Apr 23 (Apr 16–Apr 30)	Oct 17 (Oct 14–Oct 25)	177 days
Zone 7a (91 ZIP codes)	Apr 10 (Apr 2–Apr 18)	Oct 27 (Oct 21–Nov 5)	200 days

When to Plant in Indiana?

North of the Ohio River valley (Zones 5b, 6a, and 6b), plant garlic from early October to mid-November and tulip bulbs from early October to mid-to-late November. Along the Ohio River (Zone 7a), garlic goes in from mid-October to late November and tulip bulbs from late October to early December. Each window opens 1 week before the first fall frost (garlic by October 15 at the latest), so the north plants first. The table gives the dates the site computes for 18 Indiana cities, each from its nearest NOAA weather station. Evansville, New Albany, and Jeffersonville take their dates from riverfront stations (Evansville Museum and Louisville McAlpine), which put the first fall frost on November 4–5; inland Zone 7a towns such as Tell City (October 27) and Corydon (October 18) see frost 1 to 3 weeks earlier.
