Do you have moss growing on your driveway? Heavy-duty chemicals can help you get rid of moss but why use chemicals when you can get rid of them the natural way? The easiest, natural and most economical way of getting rid of them is to use a sifter to apply a layer of baking soda over areas where you see moss cropping up. Repeat the process if it rains within three days of application. The baking soda sucks the moisture out of the moss, then it elevates the pH level of the soil to prevent the plant, which can only thrive in damp acidic environment, from coming back.
