Instead of relying on a strict schedule of bottled liquid fertilizers, super soil uses a base potting mix that is “cooked” or composted with a variety of organic amendments. Common ingredients include compost, worm castings, bone meal, blood meal, bat guano, kelp meal, and various other natural minerals. This rich blend is a concentrated form of nutrients that beneficial microorganisms, fungi, and bacteria in the soil break down over time, making them available to the plant’s roots.
