The Terracycle fertilizers caught my eye on Gardeners.com. They are packaged in recycled soda bottles, first of all. The fertilizers are made from worm poop. These worms are fed an all natural, organic diet. It doesn’t smell at all and is safe to use. I bought the All-Purpose Fertilizer and Orchid Fertilizer and have been using both with success. They are $7.95 each.
