Know before you buy
While this mix is specifically formulated for the high-nutrient demands of outdoor, fast-growing plants, it can be used indoors. However, because it is a very rich, ocean-nutrient-based soil, ensure your indoor plants are heavy feeders to avoid nutrient burn.
Greenfields is pre-amended with fish meal, crab meal, worm castings, bat guano, and kelp meal, so it is nutrient-dense right out of the bag. You likely won't need to add supplemental fertilizers during the early stages of growth, though heavy feeders may require additional nutrients as they approach the flowering phase.
This blend is designed to hold moisture effectively to support vigorous growth, but it is also engineered to be free-draining. This balance prevents the roots from sitting in water, which is essential for maintaining healthy, oxygenated root systems in outdoor containers.
This soil is designed for mature, fast-growing plants rather than delicate seedlings. The high concentration of organic amendments may be too strong for young, sensitive roots, so it is better suited for transplanting established plants.
Yes, Roots Organics Greenfields is formulated with organic ingredients like bat guano and kelp meal. It is an excellent choice for gardeners looking to maintain an organic growing environment for their vegetables and flowers.
