While it is highly effective for reducing transplant shock in new plants, it can also be used to invigorate existing plants. Simply incorporate it into the soil around the root zone to help establish a beneficial microbial web.
Big Foot is a mycorrhizal inoculum, not just a fertilizer. It introduces beneficial fungi that form a symbiotic relationship with your plant's roots to actively improve nutrient and water uptake, rather than just providing a temporary nutrient boost.
