Common bird's-foot trefoil · Lotus corniculatus

Why is my common bird's foot trefoil not flowering?

Common bird's foot trefoil is a sun lover that needs plenty of energy to produce its bright yellow blooms. If your plant is sitting in the shade, it will focus on growing foliage instead of flowers. Check your light levels first.

Check these first

  1. Measure the hours of direct sun hitting the plant.
  2. Check if the plant is crowded by taller neighbors.
  3. Inspect the soil for signs of over fertilization.

Likely causes

  1. Insufficient Sunlight

    Most likely

    How to tell: The plant looks healthy but produces very few or no flowers. It may also appear slightly stretched or thin.

    What to do: Move your plant to a spot that receives at least 6 to 8 hours of direct sunlight daily. If it is in a container, shift it to a south facing window or a brighter outdoor location.

  2. Excess Nitrogen

    Possible

    How to tell: The plant has lush, dark green leaves but refuses to bloom. This often happens if you use a high nitrogen fertilizer.

    What to do: Switch to a balanced fertilizer with a lower first number, or stop fertilizing entirely for a season. Let the soil dry out slightly more between waterings to encourage the plant to shift from vegetative growth to flowering.

When to worry

It is normal for young plants to skip their first year of blooming while they establish roots. Worry if the plant is mature and has had full sun for months without a single flower.

Stopping it coming back

Keep the plant in full sun and avoid heavy nitrogen fertilizers that favor leaf growth over flower production.

Questions people ask

Can I force it to bloom?
You cannot force it, but you can encourage it by ensuring it gets maximum daily sun. Proper light is the only real trigger for these blooms.
Does it bloom all year?
No, it typically blooms from late spring through summer. It is natural for the plant to stop flowering as temperatures cool in the fall.
