MycoBoost Fertilizer, by Carl Pool, takes your plant growth to another level.  Scientific research has shown that growing plants is not only about the nutrients, but also about soil health.  And soil health includes those beneficial fungi that help plants process nutrients. With MycoBoost, we have combined a full range of slow release plant food with 4 species of Endomycorrhizae beneficial fungi for optimal plant growth. MycoBoost is an 18-6-12 three to four month premium fertilizer.
