Speaking of veggie filters... what's the earliest I could put in
watercress?
I'm in Zone 5, Hamilton, ON. My little pond is thawed, but we will
certainly be getting more frost & possibly more freezing.

Some ponders have reported their watercress growing through the snow, so it
sounds to me like it's never too early. LOL.
