Over wintering plants - another question please
I just bought (4) nice plants I want to over winter, but not in my little 88 gal. pond because I have serious plant eating fish. Just 4 Walmart goldfish that grew to be about 4-5" long and eat ANYTHING green. I've wasted money all summer long over and over until I finally give up - they eat parrots feather, water clover, mosiac plant ($$$), everything.
So, I put the new plants in a ceramic lotus pot with a mosquito dunk but my question is: Do I need to add a small pump to circulate the water or is that not necessary? It is located in a sheltered, protected area with some tropical pot plants which survive unless we get too cold but even then they're only slightly damaged, not killed, so I think the location is O.K. but I would appreciate an answer about the pump. The plants are parrot feather, 4 leaf clover (again) & a couple of water lettuce and hyacinth. Thanks.
