About MycoBloom

MycoBloom is a science-driven mycorrhizal inoculant company focused on cultivating diverse, native arbuscular mycorrhizal fungi (AMF) for use in ecological restoration, native plant production, and low-input agricultural systems. Our work is grounded in decades of research on plant–fungal symbioses and responds directly to persistent limitations in the commercial mycorrhizal inoculant industry.

Arbuscular mycorrhizal fungi form symbiotic relationships with the roots of most terrestrial plants, enhancing nutrient acquisition, water uptake, and tolerance to environmental stress. While these fungi are widespread in natural soils, they are often depleted or absent in disturbed landscapes, intensively managed agricultural systems, and nursery-grown plant material. MycoBloom exists to help rebuild these foundational soil partnerships using ecologically appropriate fungal communities, rather than generic or poorly characterized inoculants.

Why Native Mycorrhizal Fungi Matter

MycoBloom inoculants are grown using in vivo pot culture systems, in which fungi are propagated alongside living host plants. This approach maintains the natural life cycle of AMF and preserves the biological complexity of the symbiosis. We do not use genetic modification or laboratory-only fermentation techniques.

Fungal source material is collected from native prairies, grasslands, and forested ecosystems across the United States. These collections are then carefully cultured, monitored, and expanded under controlled conditions to ensure viability and minimize contamination. The result is a living inoculum containing spores, hyphae, and colonized root fragments—components necessary for successful colonization in real soils.

Importantly, MycoBloom prioritizes species and functional diversity. Natural mycorrhizal communities are composed of many co-occurring fungi, each contributing different traits related to nutrient acquisition, drought tolerance, pathogen resistance, and host specificity. Maintaining this diversity increases the likelihood that at least some members of the community will establish and function under variable field conditions.

Evidence, Research, and Ongoing Evaluation

MycoBloom is closely linked to academic research on mycorrhizal ecology, restoration biology, and sustainable agriculture. Our development process draws on:

  • Meta-analyses of AMF inoculation outcomes across greenhouse and field studies

  • Long-term experiments evaluating fungal persistence and plant response

  • Comparative studies of commercial versus native inoculants

These studies consistently show that inoculation outcomes depend on context, including soil history, plant species, management practices, and background microbial communities. No mycorrhizal inoculant—commercial or native—can overcome fundamentally unsuitable conditions.

For this reason, MycoBloom emphasizes education and realistic expectations. We provide guidance on when inoculation is likely to be beneficial, when it may have limited impact, and how management practices such as reduced tillage, appropriate host plants, and minimized chemical inputs influence success.

Product Philosophy: Diversity Over Simplicity

Many commercial inoculants rely on a small number of fungal species selected for ease of production rather than ecological relevance. In contrast, MycoBloom products are designed to more closely resemble naturally occurring mycorrhizal communities.

Our MaxDiversity formulations contain a broad suite of AMF taxa representing multiple genera and functional strategies. This approach is especially relevant for:

  • Native plant restorations

  • Prairie and grassland reconstructions

  • Pollinator habitat plantings

  • Perennial cropping systems

  • Low-input and organic agriculture

Rather than claiming universal performance, MycoBloom products are intended to increase the probability of successful mycorrhizal establishment, particularly in systems where soils have been degraded, sterilized, or biologically simplified.

Transparency and Limitations

MycoBloom is committed to transparency in an industry where product contents and performance claims are often unclear. We openly communicate:

  • How our fungi are sourced and propagated

  • The ecological contexts where inoculation is most appropriate

  • The limitations and uncertainties inherent in working with living soil organisms

We do not claim that MycoBloom inoculants are universally effective, nor that they will always increase yields or plant growth. Instead, we position them as tools that can support plant–soil relationships when used thoughtfully and in the right settings.

Liz Koziol

MycoBloom was founded in 2015 by Dr. Liz Koziol, a plant–fungal ecologist whose research focuses on mycorrhizal diversity, inoculation effectiveness, and the translation of ecological theory into applied restoration and agricultural practice. The program grew out of academic work evaluating why many commercial inoculants fail and how native fungal communities can be more effectively integrated into real-world systems.

Today, MycoBloom operates at the intersection of research, conservation, and applied land management. We collaborate with restoration practitioners, growers, land stewards, and scientists who share a commitment to rebuilding functional soil ecosystems.
