Do nematodes infest cannas? I have nematodes and have to grow nematode-resistant tomatoes because of it. I planted some cannas in the garden and they did all right for a couple years but now do not do much. I might have gotten one flower last year out of a dozen or more stalks. Cannas in pots do somewhat better for me. Do you think I have a nematode problem?
