ramuskianswered grow question 2 years ago Vivo Tricoboost is a biostimulant inoculum that contains fungi and mycorrhizae, so it's best to apply it during the early stages of plant growth, ideally after transplanting The recommended rate is usually 1-2 tablespoons per gallon of water, but refer to the product label for specific instructions. Use a sprayer to apply the solution evenly over the soil, make sure to cover the entire area where you want to plant. Happy growing!
