White campion · Silene latifolia

Why isn't my white campion blooming?

It is less common for white campion to fail to flower, and this usually happens because the plant is not getting enough direct sunlight. Check your garden spot to ensure it receives at least 6 hours of sun daily.

Check these first

  1. Measure the hours of direct sunlight the plant receives.
  2. Check for any nearby plants that might be shading it.
  3. Look for tiny flower buds that might be stuck.

Likely causes

  1. Insufficient light

    Most likely

    How to tell: The plant looks tall and spindly with few or no flower buds forming.

    What to do: Move the plant to a sunnier location that gets full sun. If it cannot be moved, prune back overhanging branches from nearby trees.

  2. Excess nitrogen

    Possible

    How to tell: The plant has lush, dark green foliage but zero flowers.

    What to do: Stop using high nitrogen fertilizers. Switch to a balanced fertilizer or compost to encourage blooming instead of leaf growth.
