Arkansas boasts a diverse climate, making it crucial for gardeners to understand their specific grow zone before planting. This article will explore the various USDA plant hardiness zones found within Arkansas and provide valuable insights for successful gardening in the Natural State. Knowing your grow zone is the first step towards a thriving garden!

Understanding USDA Plant Hardiness Zones

The United States Department of Agriculture (USDA) Plant Hardiness Zone Map divides North America into zones based on average annual minimum winter temperatures. These zones help gardeners determine which plants are likely to survive and thrive in their area. Each zone is 10°F warmer or colder than the adjacent zone.

Arkansas' Diverse Grow Zones

Arkansas' geography contributes to a range of grow zones across the state. You won't find a single zone covering the entire state. Instead, you'll find a variety of zones, requiring gardeners to research their specific location.

Zone 6a: Northern Arkansas

Much of northern Arkansas falls within USDA Plant Hardiness Zone 6a. This zone experiences average annual minimum temperatures ranging from 0 to -5 degrees Fahrenheit. Plants that thrive here need to be cold-hardy.

Suitable Plants: Many varieties of evergreens, deciduous trees, and cold-hardy perennials will fare well.

Zone 7a: Central Arkansas

Moving south, central Arkansas is largely in Zone 7a. Here, the average annual minimum temperature is between 5 and 10 degrees Fahrenheit. This provides a slightly longer growing season than Zone 6a.

Suitable Plants: A wider variety of plants can flourish here, including some that are marginally hardy in Zone 6a.

Zone 7b: Southern Arkansas

Southern Arkansas, including areas near the Louisiana and Texas borders, experiences warmer winters, typically falling within Zone 7b. The average annual minimum temperature in this zone sits between 10 and 15 degrees Fahrenheit.

Suitable Plants: A greater range of plants, including many that are not cold-hardy enough for northern Arkansas, can be successfully grown in this zone.

Zone 8a: Southwestern Arkansas

A small portion of southwestern Arkansas may fall into Zone 8a, experiencing average annual minimum temperatures between 15 and 20 degrees Fahrenheit.
