What Are Hardiness Zones? These Are the Types of Plants That Will Grow Beautifully in Your Region
It's time to identify your plant hardiness zone — here is everything you need to know, according to a gardening expert
Like most hobbies, gardening is one that comes with a jargon of its own. And to truly immerse yourself in this rewarding activity, it's best to understand the technical terms that come with it.
One of the primary terms that I took some time to truly get comfortable with is USDA zones. When I first came across this tag that was commonly featured across most plants, I found myself puzzled at the kind of role it would play in the gardening process.
As it turns out, it is probably one of the most important terms to familiarise yourselves with. To make it as straightforward as possible, we have some brilliant insights from our experts to help set you on the journey to a successfully prolific garden.
What are USDA Zones?
Overestimating the technicality of gardening terms is one of the more technical gardening mistakes made by beginners. When it comes to USDA zones, as a standalone term it may sound rather complicated but the truth is that it's a fairly easy concept to grasp.
In conversation with Lydia Beaumont, planting expert at Gardeners' Yard, she explains that USDA zones are geographic areas defined by their average minimum winter temperatures. "They help gardeners determine which plants will likely thrive in a specific region," she says.
Why is it important to know your USDA zone?
You might be wondering what all the fuss is about and why you should even give USDA zones the time of day. Simply put, being unaware of this might be the one thing that keeps your plants from blooming bountifully.
"Knowing your zone ensures you choose plants suited to your climate, reducing the risk of plant failure," notes Lydia. "It’s vital to successful gardening, as some plants can’t tolerate the cold in specific zones or the heat in others."
How do you identify your USDA zone?
Lydia tells us that you can easily find your zone using the USDA Plant Hardiness Zone Map, which is available online. "Just enter your zip code, and the map will show your zone based on climate data," she says.
Once you know which USDA zone you reside in, it'll make selecting plants a whole lot easier. And we wouldn't be surprised if your garden witnessed a notable shift in favorable planting results.

FAQs
Do hardiness zones dictate pruning schedules?
"Yes, they do," assures Lydia. She explains that just as hardiness zones help determine the best time to plant, they also guide pruning schedules. "Some plants should only be pruned when they’re dormant," she says. "And since this is influenced by the local climate, USDA zones control maintenance periods."
