Plant Success Granular is a mixture that includes multiple beneficial microbes along with kelp meal, humus, vitamins, and amino acids. The microorganisms improve the plants ability to take-in water and nutrients as they colonize the root surfaces. The surface area of the root is effectively increased, allowing plants to absorb water and nutrients in a more efficient way.


The plants utilize existing nutrients more efficiently and they become more resistant to drought as they have improved moisture storing abilities. The plants become better “linked” to the soil they are planted in and enjoy superior growth and performance. Plant Success Granular can be banded under seed, worked into seed beds, placed under cuttings, blended into potting soil, or sprinkled near roots at transplant time in order to make contact with the plant roots.
