Mycorrhiza With Attitude

Rootella® mycorrhizal inoculants are highly-concentrated and cost-effective. Groundwork BioAg has developed its products from vigorous strains of endomycorrhiza, sourced from the harsh Israeli desert. These fungal strains have evolved to be true survivors, able to adapt and to thrive in the most difficult conditions. All Rootella® products are suitable for organic farming, and contain only naturally-occurring fungi (non-GMO).
