The key to garden hacks like this is to use clean aluminum foil. All you need to do is give it a thorough washing with some dish soap and water. If you use dirty aluminum foil, you run the risk of attracting various pests to your garden. They’ll smell whatever food is left on your aluminum foil and come searching for scraps. It’s also important to wash aluminum foil because leftover food can lead to mold. Just because aluminum isn’t porous doesn’t mean mold can’t develop and grow, so be sure not to skip this important step of washing your aluminum foil before using it in your garden.
Once you have clean aluminum foil, you can use it in countless ways to grow a beautiful, healthy garden. For starters, you can mix a clean piece of aluminum foil with mulch. Not only does it work to keep away certain pests such as earthworms and cockroaches, both of which hate light, but it can give your vegetable garden some much-needed sunlight.
