When we bought our farm it came with a concrete hole in the backyard. Once upon a time it was a pond but no longer. After a few years I bit the bullet and paid for a liner. It was a good, kinda natural pond. As happens in nature sometimes, disaster hit my pond! It turned over, killing everything in it. Last summer I spent many an hour removing muck from the bottom of the pond after draining it. Did I mention my pond is not a tiny pond? I vowed to make a filter(hasn't happened yet). This year I was hoping the water lilies would have enough energy stored in the rhizomes that some might come back. Nope. The pond is now thriving with everything but water lilies and goldfish. I bought both but the 12 goldfish were gone pretty quickly. Could be a snapping turtle, cats, heron or illness. I never saw any floaters. For Mother's Day my son bought me an expensive lily from a garden center and I bought three from Lowes. Although they are not dead, they are not growing. So there's my ponding adventure. I miss my goldfish and lilies!
