At Prairies Edge Organics we bring our years of experience of planting and growing organically to you. We have seen and tried many products and have found out what works and what doesn't. We can help you avoid costly errors trying out different methods and products. Use our experience to make your plants grow bigger, healthier and faster. We have experience with many industries both large and small. From the home gardner, small farmers to municipalities, sports fields and golf courses we have all natural and organic fertilizers for any sized operation. Our most popular product is our Black Castings™ an OMRI listed worm casting product. These are pure worm castings with no fillers like compost or sand. See our Black Castings™ page for further details. VermaPlex™ is a concentrated Pro Biotic liquid derived from Pure Black Castings™. We recommend using the Black Castings in conjunction with VermaPlex. Together they provide a sustainable method of plant care. Take care of the microbial bio-diversity of the soil and the soil will take care of the health of the plants.

March 2023: Our owners are heading for retirement later this year. As we wind down operations some products will no longer be available. Please contact us to see if what you need is still in stock. We apologize for any inconvenience this may cause and will make every effort to accommodate your needs.  Thank you.
