The need to remove waterlilies from a pond during winter depends on whether they are tropical or hardy varieties:
Tropical Waterlilies:
- In non-tropical climates, tropical waterlilies cannot survive freezing temperatures.
- It is best to remove and dispose of tropical waterlilies before winter.
- Alternatively, if you wish to save the plant, the tubers can be stored in moist peat moss at room temperature and replanted in spring.
Hardy Waterlilies:
- Hardy waterlilies can be overwintered in the pond if proper steps are taken:
- Trim all leaves and flower stems to about 2 inches (5 cm) above the crown of the plant.
- Move the plant, in its container or planter, to the deepest part of the pond where the water is less likely to freeze completely.
- Ensure the crown stays submerged under the waterline to protect it from freezing temperatures.
By following these guidelines, you can properly manage your waterlilies during the winter months.
