Want the GREENEST LAWN in town? Epsom salt, the mineral Grandpa use to soak his sore bones in, has another secret use. Because its rich in two minerals that make plants grow like crazy, it can also turn your lawn super-green. And it's cheaper and safer than fertilizer! Add 2 tablespoons to 1 gallon of water and spread over the grass so it soaks in. You'll be delighted. I use it on my vegetable and flower garden as well.
