So do those tubs take freezing temps, too? I know Addy leaves hers out all year long with her lotus, right? Assume Sissy does, too, but not sure Sissy has as much freezing. This year, none of us has had much freezing temps for our winter, and we're almost into March for goodness sake.
Sissy, I tried water hyacinth, had light on them 9 hours a day, they died. I didn't have any aeration, though, so maybe that is the key. My basement is not heated, but must be about 58 as that is what my basement pond water temp is, so the temps would be good. I have a room with east and south windows, so may try them next winter in there with a bubbler. And, since this summer I will add a pond for only goldfish, I'm hoping that floating plants like lettuce and hyacinth will remain alive, as I don't think goldies bother them, right, Addy? I was looking at pics of my fish when first added the koi, and thought it was cute Shamu was in the floating ring with the hyacinths! Now I realize he was EATING them. LOL Live and learn. That's also why they did ok in my bog, no fish to nibble their roots. And, this year I will be able to get new plants earlier and put them in the bog instead of waiting until July like I did last year. I'm really excited to try the bubbler in the tubs in the wintertime in basement, though!
