Hopefully next winter that's what I'll be able to do. We're about finished digging the new pond, and my husband accidentally made the center 5' deep. He said the backhoe sunk down while he was working, and thinks maybe the water table is that high, because that area now has water! I'm thinking I'll push the pots towards that deeper area in late fall, but use the outer parts the rest of the year so I can get to them without swimming.
