I have had 3 plants in my greenhouse that have had some kind of what seems to be some kind of parasite plant get attached to them. The parasite is a very light lime green in color, shows no leaves, just a long grapevine like stem that wraps around & around the stem,attaching to the plant stem with suckers that seem to penetrate the stem. The parasite stem is about 1mm in diameter. There is a root that is almost to thin to see. The parasite showed up on 2 pepper seedlings & 1 zinnia seedling. The only things in common is they were all in the same greenhouse, an all grown in miracle grow organic garden soil Help!!!!!!!!!!
