HELP! Our naural pond is being overtaken by water hemlock. How do we get rid of it?? Our pond is home to large mouth bass, frogs, salamanders, newts, occasional visits by blue herons, kingfishers, cedar waxwings, and of course ducks (wood and mallards) all fall and winter, so we don't want to do anything that wil harm the wildlife. Thank you!!
