What exactly do I do for the pond plants during winter. I'm in a zone 5 near southern michigan. The plants that I have are hyacinth, hardy water lilies, water cress, kang kong, java moss, and java fern. Can I leave the hyacinth and lilies in there without doing anything and will they come back in spring? Oh and I'm going to keep the goldfish and minnows in there they won't die will they its about 300 gallons and 2 feet deep. Any nooby tips in general for wintering a pond?
