For 2024 we are selling 9kg bags of CIL Bio Weed and Feed at $49.99 each. As with other granular corn gluten 9kg will treat approximately 1000 square feet. Corn Gluten is a safe and environmentally friendly alternative to synthetic weed control products (now banned in Ontario). Corn Gluten is a product which is best applied in early spring once the lawn can be safely walked on (the ground doesn’t feel spongy) and late summer/early fall before the weather cools and the weeds germinate. The city of Ottawa's website also suggests an early summer application.
