floating plants in winter...??
have floating water lettuce & water hyacinth in my pond for the first time this year (someone gave me a huge barrel full of them!) & I know they won't over winter here in zone 7 but I don't have a basement & in the sheds & garage would also freeze. How can I keep them alive til Spring? If I put them indoors how much water would they need to be in & would they need a lot of light? I would hate to lose them! The lilies & other pond plants are in containers on ledges in the pond & I just sink the containers to the bottom in winter.
Thanks for any suggestions!
