    The easiest way to eliminate cannas that are already in the ground -- especially if they are in a dedicated plant bed -- is to smother them. This method is done best at the end of the growing season, but it can be done at any time. If foliage is present on the cannas, cut it off at ground level. Cover the cannas' area with landscape fabric or at least a 2-inch thick layer of newspaper. Cover the landscape fabric or newspaper with a layer of organic mulch. Check regularly for signs of new growth; if it appears, remove it at ground level.
    Also, consider moving them or offering to another gardener!
