    Rootshield plus

    Seed world has the best price on the Internet and ships promptly. I order a pound every late winter to minimize ground fungus on my dahlias. I start around 600 tubers and plants, treat them in mid May, and then give a second treatment 8 weeks later to last for the season. Before Rootshield, I would lose around 30 percent of the plants to ground fungus. Now my losses are more like 5 percent. Keep the product in the refrigerator for a shelf life of 6 months or in the freezer for 12 months.
