Plant Success Soluble is a soil drenching formula that includes multiple beneficial microbes. These 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. Also included is a specially-formulated natural root bio-stimulant. The plants become better “linked” to the soil they are planted in and enjoy superior growth and performance. Plant Success Soluble can be stored in a dry, cool area for 24 months without loss of viability.
