I have a small pond (about 190 gallons I think) with two minature water lilies. They did ok the first year but didnt grow as many leaves as I have had plants make in the past even in pretty much full sun. This last year they were pitiful. I wonder if the water heats up too much here or if it just got really out of balance, since I don't check any levels. Is there a water lily that doesnt get too large that might do better. One small replacing two minatures?
