I have taken to sinking most of my pond plants for the winter but am
unsure if that is best for the grasses.

My pond is 40 inches deep and I keep a bubbler in it to maintain a
hole in the ice. We are in zone 5B in Southern New Hampshire.

I sunk the Creeping Jenny yesterday but not the grasses. Last year I
brought the grasses inside put them in plastic bags in a cool corner
of the basement and they all croaked.

What kind of grasses? What zone are the grasses meant for? If they will
survive normally in 5B without protection I'd leave them in the pond. As
long as most plants crowns/root ball doesn't freeze they should be fine.

There are many plants that can take being totally frozen and come back,
variegated cattail, some iris, water celery and Sagittarius to name a few.

In a pond that is shallow and may freeze entirely one can bury hardy plants
in the ground and cover with mulch. ~ jan
