What is My Growing Zone

Enter Your Zip Code to Find Your Growing Zone

You can use your zip code to find your USDA planting zone. Knowing your zone helps you pick the right plants that will grow well in your area all season long.

What Are USDA Plant Hardiness Zones?

Plant hardiness zones—also known as growing zones or planting zones—are set by the United States Department of Agriculture (USDA). They are based on the average coldest temperatures in each area over the past 30 years. They show how cold it usually gets in winter where you live.

The USDA plant hardiness zone system divides the U.S. into zones from 1 (coldest) to 13 (warmest). This helps gardeners choose perennial plants, trees and shrubs, that are most likely to survive and grow well in their specific plant hardiness zone.  Certain perennial plants can be grown as annuals outside of their growing zones. 

Why Growing Zones Matter

If you've ever wondered, "What agricultural zone am I in?" or searched for planting zones by zip code, this is where to start. Having this information can help you:

• Identify safe planting and harvest times
• Know when to select cold-hardy or heat-tolerant plants
• Increase long-term plant survival
• Plan ahead using reliable climate data
• Adapt to changes in local weather and climate
• Save you time, money, and effort

How to Use a Growing Zone Map

A USDA hardiness zone map or growing zone map helps you identify your zone using historical temperature data.

• Enter your zip code: Use the tool above to enter your zip code and view the growing zone by zip code
• Check your zone designation: Each zone is a 10°F range of average minimum temperatures
• Use subzones like 6a or 7b for greater accuracy (each subzone represents a 5°F temperature difference)
• Review your frost dates: Knowing the first and last frost dates helps plan the growing season
• Account for microclimates: Urban areas, slopes, shade, and wind can all slightly shift growing conditions

Gardening Tips by USDA Zone

Cold Zones (1–5): These zones face long winters, deep freezes, and short growing seasons.

What to Do:

• Choose Hardy Plants: Select plants bred for extreme cold. Many types of perennials can also be grown as annuals in these colder regions.
• Use Insulating Techniques: Mulch heavily, use cloches or cold frames, and install windbreaks to reduce winter damage.
• Grow Season Extenders: Using frost cloth and greenhouses helps to shield plants against extreme temperatures as well. 

Moderate Zones (6–8): These areas enjoy more balanced climates with moderate winters and extended growing seasons.

What to Do:

• Diversify Your Garden: These milder winter zones enable you to grow a much wider variety of plants. Diversifying your garden with more species of plants also helps it support more pollinators, beneficial insects, and wildlife. 
• Watch for Late Frosts: Protect budding shrubs and trees from cold damages with frost blankets or covers.
• Year-Round Composting: Take advantage of milder winters to maintain active compost piles and healthy soil.

Warm Zones (9–13): These regions have mild winters and long, hot summers, with limited or no frost. Gardeners in these areas can enjoy extended growing seasons and even year-round gardening with the right plant choices and care.

What to Do:

• Choose Heat-Loving Plants: Grow summer favorites like Zinnias, Agastache, and Cosmos, that love sun and warmth.
• Manage Water Wisely: Use mulch, drip irrigation, and water early in the morning to minimize evaporation.
• Provide Shade: Use shade cloths, trellises, and companion planting to shield heat-sensitive crops during peak sun hours.
• Grow in Winter: Take advantage of mild winters to grow winter-blooming plants such as Violas (Pansy).

Gardening Year-Round by Zone

Your USDA zone is a key tool in planning not just what to grow, but also when and how to grow it for year-round success.

Climate Change and Zone Shifts

Climate change is gradually shifting USDA zones northward, meaning areas that were once too cold for certain plants may now support a broader range of species. This shift is most noticeable in the northern states, upper elevations, and transitional zones.

How to Respond as a Gardener:

• Check for Zone Updates Every Few Years: The USDA occasionally updates the map. The last update in 2023 showed that many areas have warmed by about half a zone.
• Select Resilient Plants: Incorporate varieties that are both heat-loving and drought-tolerant. Native plants and Mediterranean-style perennials like lavender.
• Leverage Microclimates: Urban areas, walls, slopes, and windbreaks can create pockets where you can grow plants normally outside your USDA zone.
• Monitor Local Growing Patterns: Track and know your frost dates, shifts in bloom time, and pest activity—subtle but clear signs of climate change. Keeping a garden journal helps spot these changes over time.

Using tools like the plant hardiness zone map, gardeners can make smarter decisions about selecting plants, frost protection, and planning the growing season.

With accurate data gathered over 30 years, the USDA plant hardiness zone system provides one of the most effective ways to predict plant survival in your region. 

Whether you're a beginner or a seasoned gardener, knowing your zone is the first step toward a successful, resilient garden.
