To grow moss on objects in your garden, such as dry stones: First, combine plain yogurt or buttermilk (two cups) and chopped moss (one and a half cups) in a bucket. Mix until the concoction becomes easily spreadable; add water if it’s too thick, additional moss if it’s too thin. Spread the mixture wherever you would like the moss to grow. Over the next few weeks, make sure to keep the burgeoning moss moist. Within six weeks, so long as it’s been cared for the moss should grow vigorously.
