Need helpful advice on winterizing a koi pond
My husband built the small koi pond you see in the pictures (and from the previous post I shared) earlier this year when our Bassett Hound passed away in her memory. We have thoroughly enjoyed it. But now, as summer is nearing fall, we have a lot of questions about what we need to do to winterize it. Will we need a heater? Do we run the fountain all winter? Do we remove the plants? Will the water lily survive over winter...etc. etc. etc.! We live in Tennessee, so our winters are mild. We do have a "deep" end in the center of the pond for the fish to go down deeper. Any advice?
