Plant Hardiness Zones

What are Plant Hardiness Zones?

Plant hardiness zones (a.k.a. climate zones) provide gardeners and landscapers insight about what can grow where. The hardiness zones in Canada range from 0 - 8, with 0 being the coldest and 8 being the warmest. Each zone is further divided into sub-zones such as 3a and 3b, with 3a being colder than 3b.

Can I plant a tree in a warmer (higher number) plant hardiness zone than listed on your website?

You can safely plant any of the trees, shrubs, and berries we sell in a warmer (higher number) location as long as you stay in Canada.

Can I plant a tree in a colder (lower number) plant hardiness zone than listed on your website?

As a general rule, it is safest to plant trees with a plant hardiness zone rating less than or equal to the rating for your location. So if you live in zone 3 you can safely buy plants with a plant hardiness zone rating of 0, 1, 2, or 3.
