How to protect your garden from frost

As we head into the middle of September, we are bound to start seeing frost in the mornings. This is a given considering some areas of Canada have already seen frost advisories, some of us have even seen snow.

A report from Statistics Canada states that 57 percent of Canadians grow fruits, herbs, vegetables or flowers for personal use.

With that in mind, it is a good time to take a look at some tips to protect your garden from frost.

First off what is frost?

Frost is a thin layer of ice that forms on a surface. It forms when water vapour in the air comes into contact with a surface that is below freezing. The water vapour then changes to ice.


  • For large plants and shrubs, cover them with a thick fabric.

  • Any plants that are small should be brought inside.

  • For garden beds apply an extra layer of mulch.

  • Any outdoor plants that cannot be brought inside, cover them with a fleece.

Environment and Climate Change Canada issues frost advisories "during the growing season when widespread frost formation is expected over an extensive area. Surface temperatures are expected to fall near freezing in the overnight period."
