Control and suppress weed growth in your garden with our Heavy Duty Weed Guard 25m. It's perfect for all garden areas including under gravel, decking and patios. It's easy to install and prevents mulch from disappearing into your soil. Overall size: L25m x W1m approx. Direction for use: Remove weeds from the area (including roots). Remove sharp objects such as stones and rake to a smooth level surface. Roll out the weed guard and secure it (if using more than one width, ensure a 15cm overlap). Cover with mulch (gravel, bark chippings etc.) to a depth of 5cm. Ensure, totally covered, as the light will encourage weed seeds to germinate, and these may grow through. Be vigilant and remove weed seedlings that may germinate in the mulch layer.
