I think it can help indeed. Last season Penn State university was warning about another bad year for late blight in our area. I started all my plants indoors from seed. Gave plants to many of my neighbors and not one of these plants were hit with late blight or any other disease! I think when you buy your plants from a nursery or chain store, you take the chance that your plants may be diseased when you take them home. These growers raise their plants on a much larger scale and in my opinion, it increases the risk of disease spreading throughout their plants. What do you think?
