Guide to the Planting Zones of Mississippi

Key Takeaways
• Mississippi spans 4 zones: The state falls in USDA Hardiness zones 7b through 9a, with the Gulf Coast being the warmest.
• Warm-season grasses rule the state: Bermudagrass, Zoysiagrass, and centipedegrass thrive statewide and are best planted in May and June.
• Zones shifted warmer in 2023: Most of Mississippi moved from zone 8a to 8b, meaning slightly milder average winter lows than the 2012 map showed.
Guide to the Planting Zones of Mississippi

The planting zones of Mississippi span U.S. Department of Agriculture (USDA) Hardiness zones 7b to 9a, meaning winter lows reach 5 to 10 degrees Fahrenheit in the north and stay milder on the Gulf Coast. Plant cool-season grasses in late August and September, and warm-season grasses from May to June.

Knowing your planting zone helps you choose plants that thrive in your climate and understand how to care for them. This guide breaks down each zone across the state, the best grasses and plants for each, and when to plant them.

If you would rather skip the guesswork, Lawn Love’s local gardening service can handle the planting for you.

Mississippi planting zone map

Zones 8a and 8b cover most of the state in between the far-north 7b and the Gulf Coast’s 9a.

The USDA Hardiness zone map assigns zones based on each area’s average annual minimum temperature over a 30-year period. Each full zone differs by 10 degrees Fahrenheit, and the “a” and “b” subdivisions split that into 5-degree bands.

This information tells you which plants can survive in your area, plus when to expect the first and last frosts of the year.

Because Mississippi spans 4 zones, frost dates and planting windows shift as you move south. The Gulf Coast’s zone 9a sees its last frost as early as February, while north Mississippi’s zone 7b can see frost into April.

Here’s a map of Mississippi with the planting zones clearly marked:

Here’s a quick look at the minimum temperature and location of each Mississippi zone:

FAQs

How reliable is a plant hardiness zone for picking plants that survive?

Hardiness zones are a reliable starting point, but not a guarantee. They show which plants can survive winter cold in your region, yet they don’t account for soil type, rainfall, summer heat, or snow, all of which also affect whether a plant thrives.

How often does the USDA update the hardiness zone map?

The USDA does not follow a fixed update schedule. The map was revised in 2012 and again in 2023, with each new version drawing on a longer and more complete set of weather station records and improved mapping technology for sharper local accuracy.

How do I find my exact planting zone in Mississippi?

Enter your ZIP code on the USDA Plant Hardiness Zone Map website for the most precise reading, since zones can shift within a single county. Local garden centers and county extension offices can also confirm which zone your yard falls into.

Can I grow plants from a different hardiness zone in Mississippi?

Sometimes, depending on the direction of the shift:
• Warmer-zone plants: Often workable with sheltered spots, movable containers, or extra winter protection.
• Colder-zone plants: Riskier, since Mississippi’s summer heat and humidity can stress them. Plants rated for your own zone give you the best odds.
