Did you know Epsom salts are one of the best natural lawn fertilizers around? They’re composed of magnesium and sulfur, both of which are highly beneficial to grass. Magnesium kick-starts seed germination, and is also a player in manufacturing chlorophyll, the substance that plants manufacture from sunlight in order to feed themselves. Sulfur, meanwhile, also helps with chlorophyll, while also enhancing the effects of other fertilizer ingredients such as nitrogen, phosphorus, and potassium. It also deters certain pests such as ground worms. With all these benefits, it’s no wonder that savvy lawn care specialists have been using Epsom salts for years. You can either sprinkle them on your lawn using a spreader, or make a liquid solution out of them by adding some water and put it in a spray bottle.
