Know before you buy
For established plants, you can create small holes around the root zone using a dibble or stake and sprinkle the powder directly into the holes. Ensure the inoculant makes direct contact with the roots for the best results.
While this is an organic product, high-phosphorus synthetic fertilizers and certain fungicides can inhibit the growth of mycorrhizal fungi. It is best to use this inoculant alongside organic soil amendments to ensure the fungi thrive.
This endomycorrhizal formula is compatible with most vegetables, flowers, shrubs, and lawns. However, it is not effective for certain plant families like brassicas (broccoli, kale) or blueberries, which typically require different types of fungal associations.
The micronized mineral carrier acts as a delivery system that helps the fungal spores adhere better to seeds and roots. This fine texture ensures even distribution and faster colonization compared to coarser granular carriers.
Keep the jar tightly closed in a cool, dry, and dark location, such as a garden shed or garage shelf. Avoiding exposure to extreme heat and direct sunlight will keep the fungal spores viable for the full two-year period.
Once the mycorrhizal network is established in your soil, it can persist for several seasons. Reapplication is primarily recommended when planting new seeds or transplants to ensure the fungi are immediately available to the new root systems.
