Growing Waterlilies
Waterlilies come in many different shapes and sizes, some are native and some are exotic. They may be grown in dams and ponds, or even in containers and there are varieties which will grow in almost any part of Australia.
- Waterlilies dislike moving water or splashing produced by fountains or
pumps. They
are only suitable for growing in still water situations.
- The pond or container should have at least 5 hours of sunlight per day during the growing season for the plant to flower.
- Waterlilies should be grown at a depth of about 40 to 50cm below the surface of the water. If planted too deep the flowers may not be able to reach the surface and if they do, may be quite small. If the water over the plant is too shallow then the waterlily will produce lots of leaves and few, if any, flowers.
- Waterlilies become dormant during winter.
- Tubers are planted into containers using a mix of 1 part composted cow manure to 2 parts of loam or potting mix. The container should have a layer of gravel or pebbles on the top to stop the soil mix from washing out when it is submerged.
- Waterlilies in containers should be lifted and divided every 3 to 4 years to avoid overcrowding. Repot into fresh mix when plants are divided.
