Why is my corn speedwell not flowering?

It is less common for this plant to fail to bloom, as it is a prolific grower in the wild. Usually, a lack of flowers on corn speedwell is caused by insufficient light or poor soil conditions. Check your plant's location to ensure it is getting enough direct sun.

Check these first

  1. Observe the amount of direct sunlight the plant receives daily.
  2. Check if the plant is growing in deep shade.
  3. Examine the soil for signs of over-fertilization.

Likely causes

  1. Insufficient Light

    Most likely

    How to tell: The plant looks stretched out or leggy and fails to produce buds. It needs at least 6 hours of direct sunlight to bloom properly.

    What to do: Move your plant to a spot that receives full sun for most of the day. If it is in a container, place it on a south facing windowsill or patio.

  2. Excessive Nitrogen

    Possible

    How to tell: The plant has very lush, dark green foliage but no flowers. This often happens if the soil is too rich in nitrogen.

    What to do: Stop using high nitrogen fertilizers immediately. Switch to a balanced, low strength liquid fertilizer once every 4 weeks during the growing season.

When to worry

If your plant is in full sun and still not blooming by late spring, it may be struggling with environmental stress. It is normal for young plants to focus on foliage growth before they reach maturity.

Stopping it coming back

Provide consistent full sun and avoid heavy nitrogen fertilizers to keep the plant focused on flower production.

Does corn speedwell need special soil to bloom?
