Root additives stimulate growth in the plant’s root system. There are root additives available for seedlings, cuttings, and mature plants. Additives such as House & Garden Roots Excelurator and BAC Flush have protective qualities that prevent root diseases and damage. Other additives such as BAC Roots, and Nutrifield Root Nectar can be used on seedlings and cuttings to stimulate the formation of new roots and root branching. Some root additives are formulated using fungicides and minerals, while others contain organic ingredients (BAC Daily).
