Finally we reach the pond’s deep water zone, which is a suitable habitat for plants such as water lilies. Water lilies take root in the soil at the bottom of the pond and prefer calm, stagnant water. Water lilies create areas of shade under their leaves and this inhibits the growth of algae. During the day water lilies are a delight to the eye but they close their flowers at night and when the weather is gloomy. The depth at which the different varieties of water lilies should be planted is shown on the label accompanying the plant. It can vary between 40 and 120 cm deep.
This means that there is a water lily for every type of pond. Water lilies are generally planted in baskets and then placed on the bottom of the pond, container, trough or tub.
