American white waterlily · Nymphaea odorata

Why is my American white waterlily not producing flowers?

Waterlilies need a lot of energy to bloom, and a lack of flowers usually means they are not getting enough light or nutrients. These plants are sun lovers that require at least 6 hours of direct sunlight daily. Check your pond's light levels first.

Check these first

  1. Measure the hours of direct sun the plant receives.
  2. Check if the plant has been fertilized recently.
  3. Look for overcrowding in the container.

Likely causes

  1. Insufficient sunlight

    Most likely

    How to tell: The plant has plenty of leaves but no buds, or the buds fail to open. This often happens if overhanging trees shade the pond.

    What to do: Prune back overhanging branches to ensure the plant gets full sun. If the pond is permanently shaded, you may need to move the container to a brighter spot.

  2. Nutrient deficiency

    Possible

    How to tell: The plant looks small and pale, and it stops producing new growth or flowers.

    What to do: Insert an aquatic fertilizer tablet into the soil near the roots every 4 to 6 weeks during the growing season. Use a fertilizer specifically designed for pond plants.

When to worry

It is normal for young plants to skip flowering in their first year. If a mature plant goes two seasons without a bloom, it definitely needs more light or food.

Stopping it coming back

Fertilize regularly during the active growing season and ensure the plant is not shaded by other floating plants.
