Hi, I've been read this forum for a while and finally decided to join today. I just dug a 30k gal pond last fall at my cottage property in zone 5 here in ontario. It's got shade in one side, the shallow end is about 4' and the deep end is about 10' in the center. I am planning on stocking fatheads(1000) and bluegill fingerlings(40)sometime in june. I've been on the fence on what I am going to plant. I'm doing one or two lilies in the shallow end and a mix of watercress and irises around the perimeter. I just got a line on a lot of dwarf saggitaria for a real good price I'm just not sure if it is winter hardy for zone 5. Info on the net is all over the map, from zone 4 to 7 as the coldest. I'd kinda like the shallow end to be a refuge for small fish since a year or two down the road I plan on adding one LMB.
Does anyone have any of this in a cold climate pond?
Also we have no hydro at the cottage and hence no filtration system.
Any advice would be much appreciated.
Thanks
