I planted 5 water lilies in Aug. and they have done ok over the pas couple months. Problem is, I planted them in the pond bottom and the water level has dropped to the point where they are in danger of freezing if we have a bad winter. I pulled three of the five out today because they were in less than a foot of water. The other two will probably need pulled as well. So my question is, what do I do now? Do I go ahead and plant them in deeper water, or should I put them in containers and back in the pond? Should I winter them in the garage and plant them again in the spring? I'm afraid they won't take root if I replant them this late in the year. They already seem to be going into dormancy.
