I've never seen a muskrat and they aren't supposed to be in central Virginia. The stems look cut I think. When I pull on a stem they fall right out though which I thought was odd. I know the ducks have been moving around all the straw I have on the dam scratching at the seeds and new oat shoots. I'm just not sure what I'm doing. This makes nearly 20 lilies that have had this happen.
I have then in 1-2 feet of water about 3-4 feet from shore in a shallow end of the pond.
Not seen Muskrat in S central VA either - although we have plenty of Beavers.
Good luck on getting it figured out because its my next step and going to need some experienced advice.
