So I have a helvola hardy water lily that grew very well this summer in a tub above ground. Now that it's getting cold, i was hoping to put it in my small ponds (one is 75 g, other is about 110 g). But I have other lotus and water lilies that I sunk to the bottom of those ponds. So my question is, would it be better to:
(1) put the helvola in a 5 g bucket, and put it in the coldest part of my basement, where the temperature fluctuates between 50-65 F (ideally for overwintering below 55 F), or
(2) put it in the pond on top of some other plants (like lotus), so it would be about 10-12 inches below the water
I'm in zone 6b/7a (just east of Washington DC).
(I may (3) end up buying a 40 g trash can, dig a deep whole in the back yard, fill the can with water and sink the plant to the bottom for the winter).
