Gardening doesn’t need to be hard. There are many tips, tricks, and ways to make it easier for yourself. One of these is knowing which gardening zone your area is in. 

In this article, I share what gardening zones are, what zone St Louis is in, and how knowing which one you’re in can help you.

Gardening Zones Explained

Gardening zones (also known as hardiness zones) are a system used to determine the quality of an area in terms of which plants grow best in it. 

Many gardeners don’t even know that these zones exist, and when their gardening attempts fail, they have no idea that a simple tweak in the way they approach gardening could make all the difference.

Currently, there are thirteen gardening zones, and these are determined by the climatic conditions of an area, which affect how certain plants grow and survive. Each zone is further divided into two categories.

Here’s a quick summary of each zone’s temperatures:

Zone 0: < −65 °F to −60 °F

Zone 1: −60 °F to −50 °F

Zone 2: −50 °F to −40 °F

Zone 3: −40 °F to −30 °F

Zone 4: −30 °F to −20 °F

Zone 5: −20 °F to −10 °F

Zone 6: −10 °F to 0 °F 

Zone 7: 0 °F to 10 °F 

Zone 8: 10 °F to 20 °F

Zone 9: 20 °F to 30 °F 

Zone 10: 30 °F to +40 °F
