Frost Free Dates throughout the United States

New Mexico through Wyoming

To use this chart, find the city nearest where you live. Adjust dates accordingly depending on whether your climate is cooler or warmer. Remember that the dates provided are averages only and will vary from year to year.

If you are using this chart to select a shipping date for vegetable seedlings, we strongly recommend a conservative approach. Tomatoes should not be set out unprotected until several weeks after your last frost date, when nighttime temperatures are in the mid 40s or above. If you would like to add a location to this chart to assist gardeners in your area, please forward this information to us at info@naturalgardening.com. Thank you!
