Xtreme Gardening MYKOS is a granular mycorrhizae inoculant for root-zone support, designed to help plants take up nutrients and water more efficiently by forming a symbiotic relationship with roots. It’s a beneficial soil fungi product built for stronger root structure and more productive growth in everyday gardening.
MYKOS is a single-species arbuscular mycorrhizal fungi inoculant, centered on Rhizophagus intraradices (formerly known as Glomus intraradices). It’s intentionally focused: it does not include other microbes such as trichoderma, and it is not an ectomycorrhizae blend. If you want a targeted endo-mycorrhizal fungi option that stays simple and specific, this inoculant fits that role.
The core benefit is how it changes the root zone. By acting as an extension of the roots, MYKOS is described as enhancing root structures and increasing the plant’s ability to source nutrients and water, supporting more efficient uptake. As the fungal network develops with the plant, it can help expand effective root reach, supporting steadier growth when plants are actively building new tissue. The product is also described as helping new plantings reduce transplant shock by stimulating new root growth, which can make the transition into a new container or bed feel smoother for the plant.
MYKOS is also positioned to help with nutrient cycling in the media, including breaking down, cycling, and retaining nutrients so more stays available in the root zone. It’s described as improving soil structure in both clay soil and sandy soil, making it a practical choice for growers who want a root-zone enhancer that supports performance in a variety of real-world soil conditions rather than only in perfect mixes.
Plant scope is broad and clearly stated: vegetables, fruits, herbs, and flowers are all called out as a good match for this mycorrhizal inoculant. It’s also described as suitable for all types of growing media, which helps it fit into many garden styles without overthinking the substrate. This is a good fit for growers who want a granular inoculant with a single-species mycorrhizae focus, aimed at enhanced root structures, improved nutrient and water uptake, and smoother establishment for new plantings.

Funneliformis mosseae is important because it forms a living extension of the root system that helps plants absorb hard-to-reach nutrients—especially phosphorus—while improving water uptake and stress tolerance. What makes it unique is that it doesn’t just “support” roots from the outside; it builds a microscopic network that actively transports nutrients and water back to the plant, often leading to steadier growth and fewer nutrient-related problems.
Rhizophagus intraradices is important because it forms a living root partnership that expands the plant’s nutrient and water reach—especially for hard-to-move phosphorus—making growth steadier under stress, which is unique compared to most inputs because it must colonize the roots to work rather than simply being absorbed like a typical nutrient.
