Watergarden viewed from the Gourley deck in the Smoky Mountains of TN the garden is on W. Millers Cove in Walland. Caring for watergardens lessens the longer they have been created. Mine I used to freeze water jugs to cool it down before shade growed around it. The lower side is high , so planted vines on the rocks to keep the sun from heating the rocks to make the water even hoter. Waterlilies, help shade, and make oxygen for fish. The fish do not have to be fed after the water reaches a constant 50 or below in Winter. Just dip out with a net the unwanted left dying plants, I used to take a pole with a blade tool and cut each branch of the lilies. I had a lot of fun raising fish, and caring and learning about plants. Garden the photographer worked on in late 80’s, it became a habitat for Anolis Carolinensis lizards.
