The Jam Man
I have read two opinions on this. One says do not trim the cattail and do not submerge. The other says trim and submerge. I am in zone 6a. What's the best way to overwinter my dwarf cattail? My pond is above ground-30" deep. I was planning to trim and submerge on a concrete block in the middle of the pond at the mid water level. Same with my hardy dwarf water lily.
