Did I just make a big mistake? I have a ten acre pond which I use for fishing. A friend just gave me about a hundred water hyacinth plants and a put the at the shallow edge of my lake, without thinking of consulting you first. I did it yesterday afternoon, and I can still rake them out if this was an error. There isn't much plant cover where I put them and I thought I was doing the right thing, but then the idea hit me tnat it might be a bad idea. If it helps, I live in northern California where the temperatures drop to freezing for a short time every winter. Your advice...
