Fortunately jumping worms haven’t made it to our gardens yet. Luckily, we already follow best management practices for plant production that will prevent the spread of jumping worms and other soil-borne invasive species. These best management practices are outlined by the University of Minnesota Extension offices. At Prairie Moon, our dormant bare-root plants are grown in outdoor garden beds. When we dig these plants for sale, they are inspected and all the soil is washed off the bare roots. The clean roots are then packaged in a soil-less, peat-based medium for shipment. Our greenhouse-grown potted plants are started from seed and grown in a soil-less growing mix that is sourced from a reputable distributor.
