Grower’s Tip:
Beneficial fungi like mycorrhizae and trichoderma colonize on and around plants’ roots forming a symbiotic relationship. This relationship helps increase root mass up to 1000 times enabling more efficient nutrient and water uptake. These fungi also benefit plants by releasing natural chemicals that help dissolve elements like phosphorus and iron that are less available to plants in their natural state.
