I have never planted canna lilies before, and had, I thought, picked out a perfect pink one yesterday at our local nursery. It was very reasonably priced, and I questioned the owner about it. Then she started telling me how everyone in our area has trouble with them being infected with worms......well, honey, that did me in. I said, back to the drawing board and put it back.

Are worms a common problem here with cannas? How do you control them or is it worth the trouble?
