Garden Planting Frost Dates By Zone

If you plan to start a garden this year, it is crucial that you know your planting zone. By this you will be able to know which plants grow well in your area, and when it is safe to plant them.

Check out this map, and find your location to determine your planting zone. Then research the plant varieties you’d like to grow, and find out which grow best where you are.

You’ll also need to know the average expected frost free dates for your area so that you don’t plant too soon and lose your seedlings to freezing temps. Of course, winter weather patterns will vary, but you can use the following chart as a guide.

  1. Pam, you’re my hero! I am in LOOOOVE with this seed starting chart. I sat for hours today trying to calculate when to plant several things, and started making a calendar of starting seeds and planting in the garden. You don’t know how much time you just saved me. I cross referenced this downloadable chart with what I have so far, and it matches up almost perfectly. Thank you so much!!

  2. I thought you and your members might be interested in an interactive version (using google maps) of the current USDA zone hardiness map at http://www.plantmaps.com/usda_hardiness_zone_map.php
    There are also detailed interactive zone maps for each US State such as Tennessee for example:
    http://www.plantmaps.com/interactive-tennessee-usda-plant-zone-hardiness-map.php

    There is a detailed zipcode to zone search using the latest US postal service zips and giving the reader their zone down to the sub zone level (a or b). By entering your zipcode you can also get first/last freeze, Heat Zones, drought conditions and annual climatology for your area.
    You can also embed the zip to zone search in your website using the plantmaps widget at http://www.plantmaps.com/hardiness-zone-zipcode-search-widget.php

    Thanks
