winterize a small pond

Hi Karen,
Checkout the more competently moderated message boards such as Koiphen
or koishack, I doubt any serious water gardener or ponder would want
to waste their time on message boards which have deteriorated to the
extent that rec.ponds, or scamericanponders have sunk

Hello,
I live in Missouri and I have a small plastic pond tub approx.35 gal.
There are no fish,( well there was but they disappeared late summer we
suspect largebirds). We do have a few plants in containers and a few
floating. How do I winterize the pond to prevent the plastic liner
from cracking? And is it possible to keep the plants alive outside?
Please respond ASAP winter is upon us.

Thank you,
Karen

You want to save your plastic liner so you have to use heater rod or any heater which can easily workup your pond so your plastic will not break by it.
