The microbes help break down organic matter into forms that are easier for roots to absorb. This process improves overall soil health, leading to more efficient nutrient uptake and stronger root systems.
Yes, Roots Organics Big Worm is an organic soil amendment and is perfectly safe for use with edible gardens. It provides a natural nutrient boost that supports healthy growth for both vegetables and herbs.
