Gorgeous gardens! Loving the tour! I have a koi pond also and it is under a large dogwood tree and a very tall pine tree. I bought the vinyl type window screen and sewed it together on my sewing machine to make it large enough to cover my pond. I put it over the pond just before the leaves start falling and leave it until about Feb. It really cuts down on maintenance. Before I made the cover out of window screen, I had a cover out of netting I bought and the pine needles and lot of the leaves just went right through it.
