How to 'winter' a Bulb


I have a Nymphaea Maculata (Tiger Lotus) that looks like it could do with a rest period. Its growth has practically stopped and it makes no attempt to send up leaves to the surface.

I've heard that you can give them a rest period by removing them from the tank and keeping them in cool, shallow water. There doesnt seem to be much info on the specifics of this so I thought I'd ask on here and get some detailed information so I can do it right.

this is info on aponogeton bulbs, but it should work just as well with lotus bulbs.

Place the tuber in the sand and store it in a cool location like the basement at a temperature of 60-65F for a period of six to eight weeks. At the end of this time, replant the tuber in the tank, making sure that you have it right side up. If the plant was able to store enough food during its last growth period, it should begin to sprout within a couple of weeks."
give that a shot if you can't find more info specific to tiger lotus bulbs.

Personally I'd love for my lilies to stop reaching for the top.

I have kept tropical lilies from my pond in the basement for the winter. Cold and moist and dark. In early spring I've had them sprout on their own in the basement, long before it's safe to put them out again.
