    You could try using a product called Finale. It breaks down easily so that it doesn't remain in the soil. Your best bet, however, may simply be digging it up and then spraying the sprouts that pop up until it is finally eradicated.

    Early spring or early fall is the best time to plant mondo grass.

    All of these plants need to be dug up and brought in to at least the garage for the winter. They cannot survive the cold where you are, even if mulched. The canna bulbs can be stored. Here is information on that: https://www.gardeningknowhow.com/ornamental/bulbs/canna/storing-canna-bulbs.htm

    As for the grasses, you can put them in pots and allow them to go dormant in a cool, dry place. Water them once a month and bring them back out in the spring.

    Pruning can take place in late winter to early spring. You can cut the old grass down to make room for the new shoots.
    Generally you can cut to about 3 inches in height. You may be seeing new grass growing in.
    A slow release balanced fertilizer can help with color on a Mondo Grass, apply in spring and summer.
