EM™ is useful in growing nursery crops, container grown plants, hydroponics and in a huge variety of vineyard applications.

Benefits of using EM™

EM™ improves the structure of the soil, increases its fertility and radically improves biological diversity. EM suppresses soil borne pathogens, both through their direct action and the probiotic substances they produce. The microbes in EM™ work by being dominant over other soil microbes. As a result, this encourages the bulk of the other microbes in the soil to 'follow' them and in doing so suppress the activity of the smaller group of negative or 'opportunistic' microbes.

  • EM is something I swear by in the garden. I saw the difference it made in my Mum’s vege garden and I wanted the same. You can use it as is, or mix it with seaweed, Neem, bactur, copper, or whatever you use to feed and manage your garden. I use EM Foundation product to prep my soil for planting, and EM Foliar Enhance for quick pick me up feeds through the season. Organic and natural.
