Small water tubs and ponds change water temperature very quickly. Large ponds change water temperature very slowly, which can be bad news when cold weather comes; the ponds will heat up very slowly. Solar-powered aerators can be a big boon in keeping water circulated throughout the pond. Potting soil can be used in a waterlily pot, but many growers prefer calcined clay mixtures, which look like clay-colored coffee grounds. These clay materials allow roots to penetrate the medium while still allowing oxygen into the root system. Fertilize your plants with slow-release fertilizer such as Dynamite or Pond Tabs 2 or 3 times in the growing season. Press the fertilizer into the mix near the stems and cover up the fertilizer with soil. Once exposed to abundant sunshine and in proper soil with fertilizer, water lilies can grow amazingly fast. The biggest problem people run into is that the water quickly turns green. This usually a short-term algae bloom, and will subside as the lily pads grow to cover the water surface. Water lilies thrive in sunshine, algae cannot grow in shade. As the leaves cover the water, the algae disappears.
