I'd like to grow some watercress. One of best areas would be the shoreline, above and below the mean water line, on the north side of my pond. It stays wet most of the year and it gets sun nearly all day long. A number of years ago I created a wetland above this shoreline that acts as a water filter for runoff from a pasture above my pond. I recently planted a bunch of horse radish in it. I wouldn't mind if the watercress invaded that area, but I don't want it taking over my pond.
I'm concerned, as it is listed as an invasive species by many states -- but not Virginia, nor West Virginia. I've looked at a whole bunch of university and government websites, but they don't say what it might do in ponds like many of us have. It sounds like it can't live in more than six inches of water, but . . .
Anybody have experience with growing it?
Thanks,
Ken
