    You can cut down the flower stem as far as you like, but make sure to leave the foliage as the plant needs this to store energy for next year's flower. They often do not rebloom on the same stalk; however, cutting the old flowers stalks will sometimes encourage new flower stalks to grow.

    Actually, this is common behavior for cannas. They will normally dieback around summer, especially when it's been hot, but may return in fall go dormant again over winter and return in spring.

    Canna lilies often develop brown edges when conditions are less humid than they are used to. Another reason may be salt burn. Salts in the water and in fertilizer can build up over time, accumulating along leaf edgesand causing leaf drying browning. It's important to water deeply and slowly. At least once a month, water deeply enough to "leach" or push salts well below the root zone. Also, if they are receiving too much direct sunlight, foliage can turn brown. Finally, canna leaves may turn yellow/brown as it enters dormancy.

    You can plant the seeds but it will take a while for the plants to grow or bloom using this method. It is easier to simply divide the plant rhizomes.

    No, canna needs to be dug up and stored for the winter. They cannot survive the cold where you are, even if mulched. Here is information on that: https://www.gardeningknowhow.com/ornamental/bulbs/canna/storing-canna-bulbs.htm
