How to divide water lilies-taken from the net
Plant below needs dividing badly
Picture below shows how after you remove the plant from the container you can cut the bottom off,since most of the rhizome are growing in the top half of the container.
Picture below shows how to cut the roots off,use sharp scissors or a sharp knife to cut them off.
Picture below shows what the plant will look like after cutting the roots.
Use a sharp knife to cut the rhizome when you divide it,a sharp knife will leave a nice clean cut. If possible leave at least 4 -5" from the crown when you cut the rhizome.
Below are all the divisions taken from the original plant.
Propagation of the "Eyes"
Carefully remove the lily from the pot. Wash away the potting material from the tuber so that you can see it clearly. Some lilies produce small protruding bulbs or "eyes" with active growing tips along the body of the tuber. If your lily has developed eyes, these can be pulled or cut off and placed in small, no-hole pots or trays to grow and develop. They will need adequate light and warmth, so a greenhouse is the best place to grow the eyes until they are large enough to transplant as tubers. Otherwise you can leave them attached to the tuber to mature naturally and divide the main tuber as follows.
Division of the Tuber
Large lily tubers with multiple growing tips can be divided into sections. Each section must have both a strong growing tip and slender dark feeding roots. Wear gloves when handling lily roots, as some species can stain your hands. Using a sharp knife, cut the tuber into sections. Remove the long white anchor roots from the new divisions, making a clean cut close to the tuber. Leave the smaller feeding roots intact.
Trim away all large open leaves in the same manner. If left on they will make the newly planted tuber too buoyant. Do leave attached young foliage which has not yet unfurled. Follow this procedure on each new section. Now you are ready to pot the divided tubers.
