Delivers long-term benefits without chemicals. Jobe’s Biozome is a unique and proprietary blend of beneficial microorganisms Archaea, Mycorrhizal fungi and healthy bacteria. Archaea, a recently identified microorganism found in some of the planet’s most extreme environments, such as hydrothermal vents on the ocean floor. In garden applications, scientists have discovered that these microbes actually clean the soil, returning it to a healthier, more natural state. Jobe’s Biozome contains a proprietary species of Archaea that quickly breaks down complex hydrocarbons and minerals into basic nutrients and trace elements that plants readily absorb. Mycorrhizal fungi expands the surface-absorbing area of the roots by 100 to 1,000 times, sending out filaments that act as extensions of the plant’s root system, helping plants absorb more water and nutrients. In return, the fungi receive essential sugars and other compounds from the plant roots, fueling their own growth. Finally, the healthy bacterial strain in Biozome improves the soil structure and quality, keeping nutrients near the roots. Jobe’s Organics Flower & Rose granular fertilizer is OMRI listed and may be used in certified organic food production according to the USDA National Organic Program. Jobe's Organics Flower & Rose fertilizer is also available as an organic fertilizer spike. Jobe’s Organics Flower & Rose Fertilizers will help your rose garden thrive.
