I'm not sure if my plants will survive my current setup, hoping for feedback. I reconfigured my turtle pond with multiple stock tanks to hold plants and keep them from the turtles, and those tanks have a lot of plants that are in pots filled with gravel or kitty litter/gravel. About 3/4 of each pot is submerged, the rest is exposed to the elements. Will those plants make it through the winter with the plant crowns exposed like that? Each tank will be covered with greenhouse plastic on a pvc hoop frame, so temps will be a bit warmer than the outside air. My lows will get down to around 25F, but much of the winter, it will be in the 30s at night . should the plant crowns be submerged? And what about the water itself? if it gets icy on top, will that wipe out the plants? The pump will continue to circulate water in the winter.
Plants include Canna, plantain, taro, society garlic, water celery, curly leaf juncus rush, parrot's feather, creeping jenny, calla lily and a few others. Of these, the first 4 I've overwintered just fine outdoors, but in dirt, in a gravel bog. This time round, there is water surrounding the pots, no gravel, and the plants are not in dirt, at all.
The setup includes a 3' deep pond, water is pumped out into a series of above ground stock tanks, with gravity flow between them, then back into the pond. Images of a couple of the tanks. Tanks have rocks on the bottom, with plants on top.
