USDA Hardiness Zone Fun Facts

If you have ever had the opportunity to relocated to a different part of the country you understand why it is important to know the weather conditions.   Being aware of a hardiness zone when it comes to growing successfully is a similar situation.  In this post, I share why you should care about hardiness zones.

What is the USDA Hardiness Zone Map?

The US Department of Agriculture created the USDA Plant Hardiness Zone Map to provides a standard climatic conditions relevant to growing plants successfully. Agriculture industry uses this data to define what plants grow best in what areas of the United States.  By understanding what zone you’re located in, you can find out which plants will grow best in your area and which won’t.  Below is a copy of the map you will find on the USDA site.  I recommend checking out the link (by clicking on the image below) to find more details.

USDA Hardiness Zone is Important  To ME Becuase:

By learning your zone you can easily find how many growing days you have to use in the season.  Almost any vegetable will grow in zones 3 and up.  in zone 3 or higher and has at least a 123 day growing season – enough to grow squash, peas, kale, tomatoes and much more!  Knowing your zone also tells you when it is safe to plant outdoors.  Many plants like squash, corn and cucumbers can not tolerate frost.

Now Let’s Get Growing

Below are a few of my favorite things to grow in zone 5b.  If you check the vegetable descriptions you can grow these in most other zones as well.  Be sure to reach out to me with any questions you may have.

If you want to get really crazy.. come grow in a dome like I do!
