Organic Gardening Products

Organic soil amendments and fertilizers differ from chemical fertilizers because, in addition to feeding the plants, they also build the soil’s structure. This is key and synthetic fertilizers do not do the same. Chemical fertilizers also damage the environment. Organic fertilizers, on the other hand, are made from plant and animal sources or from rock powders and do not cause damage to the environment.
