A fun, easy, and environmentally friendly way to plant large or difficult to reach areas is with seed bombs. A typical recipe for seed bombs is: 5 parts dry powdered natural clay, 3 parts dry organic compost,1 part seed,1-2 parts water. After mixing together all of the dry ingredients, slowly add water to the mixture until the mixture sticks together but isn't too wet or so dry and crumbly that you cannot roll it into balls. Roll into quarter-size balls. Let dry for 48-72 hours. Bombs away!
