Lily pads, or water lilies, need 4 to 6 hours of sunlight a day. They should cover no more than 50 to 75 percent of the surface of a pond. They can be removed from the water if the pond gets too cold in the winter as long as they are planted in pots that allow the height to be adjusted. Regular fertilizing is important.Continue Reading
To plant water lilies, use a wide, shallow container. If the container has drainage holes, line the inside with burlap. Use a heavy type of soil without material, such as peat, that will not float away. Press aquatic fertilizer pellets into the soil before planting. Trim old roots and leaves off the tuber leaving only fresh, vibrant ones. Plant it against the side of the container with the growing end angled upward and towards the center. Cover the soil with some sort of gravel or small rocks to stabilize the soil. The base of the pot should be 12 to 18 inches under the pond so that the leaves float. If the pond is too deep, prop the pot up with rocks.
Once a month, fertilizer should be pressed into the soil. It should not be released directly into the water or it will affect the pH balance. Flowers and yellowed leaves should be purged. Flowers usually bloom in the fall. In winter, hardy water lilies do not have to be removed, but instead placed in the deepest part of the pond where they will not freeze. However, if the pond is frozen or drained in the winter, the plants should be removed and stored in plastic bags.Learn more about Outdoor Plants & Flowers
