It was wonderful having Steve and Monte visit today and give me feedback on the pond, it’s filtration and my fish. Having two koi experts in your backyard is real treat. I’m so grateful for this forum and especially, Nancy, to you for starting the thread on growing impatiens in water. It turned out to be a wonderful way to add color to the pond without a lot of work. Even my husband observed that it was hard to believe that these things started out as two inch seedlings. Each group of three tiny plants now provided an area 3 feet wide of continuous color. Easiest gardening I’ve ever done.
