Welcome to the Forum!
Can you elaborate on your objective? Size of pond, type of plants and so on. Location should be added to your "User CP" so we can better help you.
My pond size is about 3' X 6', with a plastic liner. I just have a couple water lillies for the water plants, then a butterfly bush, plum tree lilac bushes, and magnolia bush surrounding the area away from the deck. I had some fish die over the winter which you responded to, so thank you. If you need more information, let me know.
