Winter Care for Water Lilies in Cold Climates

Overwintering Hardy vs. Tropical Water Lilies

In Utah and similar climates, water lily survival depends on the variety and pond depth. Hardy water lilies can overwinter in ponds at least 18 inches deep. The plants go dormant and resume growth in spring.

Tropical Water Lilies Require Special Care

Tropical lilies cannot survive freezing. Before winter, remove the pot from the pond and store it in a cool (not freezing), dark area like a basement. Keep the soil moist. Return the pot to the pond in spring when water temperatures exceed 65°F.

Key Steps for Hardy Lilies

• Ensure pond depth is 18+ inches.
• Leave pots in the deepest part of the pond.
• Remove dead foliage to prevent decay.
• No additional heating needed for hardy varieties.

Proper identification of your lily type is essential for correct winter care.
