An important step in weed prevention is to ensure the topsoil and other covers you are using are weed-free. If the package does not specifically state that the product is ''weed free,'' you could be unknowingly putting weeds into your garden. If you are planning a new garden or have a weed-plagued garden, removing old topsoil and replacing it with weed-free soil is a great way to get a fresh start. Throw out old soil to prevent weed seeds from propagating.
