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 Plant Hardiness Zone National Map
Find your location (city, state) on the map above. Use the color code guide to find your hardiness zone on the right side of the image. Once you know your planting zone, use the chart below to find your frost dates.
|Zone||Avg Last Frost||Avg First Frost||Average Growing Days|
|1||May 25||August 25||92|
|2||May 15||September 1||109|
|3||May 15||September 15||123|
|4||May 15||October 1||139|
|5||May 1||October 15||168|
|6||April 15||October 15||183|
|7||April 1||October 31||213|
|8||March 15||November 15||245|
|9||February 15||November 30||290|
|10-13||No Freeze||No Freeze||365|
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.
In this post I share the mystery squash plant that appeared in my home garden landscape. This plant provided over a dozen zucchini-like harvest from Summer to Autumn season. You will see the video and images featuring this mystery zucchini squash vine I grew.
In this post I reveal the mystery tomato growing in my raised bed garden. This variety is an amber color grown organic. video and growing details here.
