About Compost

Providing essential nutrients, naturally.

High quality soil is the basis for plant growth. While GardenSoxx® can be filled with any brand of media, GardenSoxx are designed to be filled with a high quality compost material. 

Engineered for maximum plant growth

Plants depend on essential nutrients to properly grow and develop. They require primary macronutrients nitrogen (N), phosphorus (P) and potassium (K) for growth, development and overall function of the plant. They also require secondary macronutrients nutrients calcium (Ca), magnesium (Mg), and sulfur (S); as well as micronutrients iron (Fe), boron (B), copper (Cu), chlorine (Cl), Manganese (Mn), molybdenum (Mo), zinc (Zn), cobalt (Co), and nickel (Ni).

Compost is rich with macro and micronutrients. Our GrowingMedia typically has a 1-1-1 NPK analysis, and also contains important micronutrients (Ca, Mg, Fe, S, Cu, B, and Mn) in a form that is readily available to plants. These nutrients are slowly made available for root uptake over a long period of time, minimizing nutrient loss through runoff.

Disease suppression

Organic matter in the soil enhances the proliferation of organisms, which not only promotes root development and assists in the extraction of nutrients from the soil, but also helps suppress specific plant diseases, such as Pythium and Fusarium, as well as nematodes. (Faucette, et al. 2007)

Water retention

Compost has the capacity to hold up to 20 times its weight in water. Organics create passageways in the soil for air and water. In this way, compost enhances the physical make-up of soil by improving soil structure, porosity and bulk density.

Locally sourced

Compost is a locally sourced recycled media–another feature that makes GardenSoxx a sustainable agricultural practice. We partner with compost manufacturers across the country to distribute GardenSoxx filled with their locally-made compost, which has been certified for quality assurance.

Characteristic of good compost material

GardenSoxx can be filled with any bagged planting media or compost. When buying compost to use as a growing media, we recommend using Seal of Testing Assurance (STA) Certified compost that is well-decomposed, has a pH between 5.0-8.0, and is free of any refuse, contaminants or other materials toxic to plants.
