Water lilies are a popular pond and water garden plant because they are easy to maintain and come in a wide variety of colours. Water lilies are a floating-leaf plant, which means that their roots extend down to the pond floor, but their leaves and flowers float on the water's surface. The easiest way to maintain your water lilies is to pot them first, then place them in your pond or water garden.
Add sand or clay to a wide, short flower pot.
Add water to the flower pot until the clay or sand is thoroughly wet.
Create a hole in the sand or clay and place the water lily's roots deeply enough into the soil that the crown is at least 1 inch below the soil level.
Push the soil around the water lily's roots.
Add pea gravel or additional sand around the water lily. Pack the soil lightly.
Place the flower pot in the pond. Make sure the water is at least 6 inches deep.
Keep your water lily moist while you replant it. Water lilies are fragile and dehydrate easily. Plant your water lily as quickly as possible to avoid permanent damage.
