I winter my water hyicents over in zone 6. I plant them in a tub in August here with no holes in the bottom with yard dirt and keep water in the tub. Then in Oct here I bring them in my basement under lights. If they survie through Feb or March in April they look ragged. Then I take them outside in April and put them in my cold frame tub. Which has water in it and I put an old window over the top. After a couple weeks when they start looking better I pull them out of the dirt. Works for me
Thanks Vickie.
I am going to try a few methods, and see what one works for me.
I have a 6 ft. reef lighting system on a fresh water tank. Right now I am just running the atinics, But will change them out to the broad spectrum lights for the winter, The tank stays 78 to 82degrees.
I had fresh water plants in the tank for years. The monsters that were in the tank have been traded in for some fancy gold fish. So ,I am confident some will survive the winter indoors.
Then there is the tub in the basement method with the 2-250watt metal halides,should do for that .
Then if I can get the boys to build the green house, I have all the glass I need for a 3 sided + roof for that.
Something has to work. I just cant see not giving it a try with the hyicenth. I am actually not worried about any of the Lillies, except the small yellow. The larger ones that were a gift, have wintered over in a pond like mine for over 10 years.
I will do all I can to make all of the plants happy through the winter months.
again thanks for everyones help.
