March is early in the season for lilies so the range stocked is limited to those which are ready to be planted out. There is a fair cross section of favourites and more varieties will be brought into stock when they are ready. Choosing your lily Lilies range enormously in price and appearance. As well as looking beautiful lilies perform the important function of providing shade to the pond which gives cover for fish and reduces algae growth. Lily roots should be well anchored in the soil with the growing tip just above the surface.
Lilies grow and flower best in full sun.
If the water in your pond is so dark and cloudy that you can no longer see them they will not get enough light. The best way around this is to prop the lily up and first and gradually lower it. While some water lilies will tolerate less than 2' depth they will not generally perform well in shallow water. It is better to go for lily like plants which will tolerate a broader range of depths. Use sachets or tablets.
