I plan on covering the pond with a plastic liner.
Do I need to have some kind of open hole somewhere for oxygen ?

Zone 7, koi ponds are now completely screened. Cannas are out of the pond
and in containers waiting for frost to knock them back. Taros up on the
patio to be debugged before bringing in. D.pond closing got pushed back a
week, hope that doesn't bite us in the butt. Lily pond will be closed down
as soon as I've saved enough milk bottles to help support the screen. ;o)

How about you, what is your zone and what have you done so far to

prepare for hibernation? ~ jan
