bulbous buttercup · Ranunculus bulbosus

Why is my bulbous buttercup not flowering?

If your buttercup is healthy but refusing to bloom, it is likely not getting enough light. Check your plant's location to ensure it is receiving enough direct sun.

Check these first

  1. Measure the hours of direct sunlight the plant receives.
  2. Check if the plant is crowded by other taller plants.
  3. Examine the plant for signs of pests that might be eating the buds.

Likely causes

  1. Insufficient light

    Most likely

    How to tell: The plant looks tall and stretched out with few or no buds.

    What to do: Move the plant to a spot that receives at least 6 hours of direct sunlight daily. If indoors, place it in a south facing window.

  2. Improper dormancy

    Possible

    How to tell: The plant foliage looks fine but never produces flower stalks.

    What to do: Ensure the bulbous base has a period of cooler temperatures after the growing season. This cycle is necessary for the plant to set buds for the next year.

When to worry

It is normal for young plants to skip flowering in their first year while they establish their roots. Worry if the plant is mature and still shows no signs of buds after a full season of sun.

Stopping it coming back

Provide consistent full sun and avoid over fertilizing with high nitrogen products, which encourage leaves instead of flowers.
