Frequently asked questions

Are vinegar-based weed killers effective in Canada?

Horticultural vinegar can be effective on young weeds, but it is non-selective and can harm any plant it contacts. Always check the label for the correct concentration and application instructions.

What is the best weed killer for lawns in Canada?

Iron-based products like FeHEDTA are selective and target broadleaf weeds while being safe for lawns, making them a popular choice in Canada.

Can I use corn gluten meal as a weed killer?

Corn gluten meal acts as a pre-emergent herbicide, preventing seed germination. It is effective if applied correctly before weed seeds sprout.

Is glyphosate banned in Canada?

Glyphosate is not banned federally, but its use is regulated. Some provinces or municipalities may have restrictions on its cosmetic use. Always check local regulations.

How do I know if a weed killer is approved in Canada?

Look for a Pest Control Product (PCP) number on the label and verify its registration with Health Canada's Pest Management Regulatory Agency (PMRA).
