Plant hardiness zones updated


 

Canada is warmer by one to three degrees than in the mid-1800s, so the federal government has updated plant hardiness zone maps.

They are designed for gardeners, not farmers, the creators caution, yet the report said “these changes have significant implications for plant growth and survival across the country.”

Federal employees who are part of the Canadian Forest Service have created a website called www.planthardiness.gc.ca.

It contains updated maps with new plant hardiness zones for Canada’s different regions.
