New pond owner here, just dug and filled a 30’x90’ oval shaped pond this summer. Last night I planted several arrowhead plants around the pond edge and tonight when I got home (first thing I do is always walk over and check out my pond) I noticed all the arrowheads are gone, all of them. I have around 25 domestic ducks that free range my property and suspect that they ate them. Is there anyway I can establish arrowhead at the pond with the ducks spending a lot of time there? Should I just give up on that idea for now? Kind of disappointed cause I’ve always liked arrowhead.

Thanks guys
