Premier Horticulture Pro-Mix BX Biofungicide & Mycorrhizae

The biofungicide is a naturally occurring bacterium that colonizes the root system, creating a protective barrier against common soil-borne pathogens like Fusarium, Pythium, and Rhizoctonia. It helps suppress these diseases before they can damage your plants, leading to healthier, more resilient root systems.

Mycorrhizae are beneficial fungi that form a symbiotic relationship with plant roots. They effectively extend the root system's reach, allowing the plant to absorb more water and nutrients from the soil, which typically results in faster growth and better stress tolerance.

Pro-Mix BX is a versatile, general-purpose medium that works well for both. Its structure provides the aeration and moisture retention needed for delicate seedlings, while the added biologicals provide the long-term support necessary for successful transplanting and mature growth.

Because of its high-quality peat base, this mix holds moisture very well. You should monitor your plants closely at first, as you may find you need to water slightly less frequently than with standard, less absorbent potting soils.

While it is engineered for professional greenhouse environments, it works perfectly for indoor houseplants. The consistent texture and disease-suppressing additives make it an excellent choice for container gardening where you want to minimize the risk of soil-borne issues.
