Duckweed over taking pond
Well, Spring is here again.
I have, in my backyard, a pond that is about a quarter to half an acre in size. Not exactly sure about it's depth, but it was originally dug for 15 feet. I believe the deepest part is around 10 feet.
Anyhow, I purchased the home Mid to Late June last year, so the pond was covered in what I believed to be duck weed. They were small flat green leaves. If you are familiar with shogun shell gun powder, this is what they looked like.
I could skim this stuff of the top with a net, but the hole would fill in almost immediately.
Since it is spring now and I have the chance to halt or curb the problem before it begins, I would like some advice on how to keep this stuff from covering my pond this year.
A friend of mine has offered the advice and materials to treat it with copper sulfate -but that was used to clear moss. Which I could not find in my pond last year. Only these tiny thin leaf things. Again, I am under the impression that they were duckweed or duckwart.
Any advice? There is a small portion open from the ice, but after tomorrow, the pond should be completely clear of ice. I have 3 geese in it now. I am looking to re-stock with game fish this spring......if I can keep this plant from covering the whole pond.
Thank you in advance for your valued assistance.
