Why is my corn speedwell growing so leggy?

Leggy growth happens when your corn speedwell is stretching out to find more light. Check your current light levels to see if the plant needs a brighter spot.

Check these first

  1. Observe how many hours of direct sun the plant gets.
  2. Rotate the pot to ensure all sides get even light.
  3. Check if nearby plants are shading your speedwell.

Likely causes

  1. Insufficient light

    Most likely

    How to tell: The stems are long and thin with large gaps between the leaves.

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

  2. Excessive nitrogen

    Possible

    How to tell: The plant grows very fast but the stems are weak and cannot support the foliage.

    What to do: Switch to a fertilizer with a lower nitrogen ratio. Avoid overfeeding during the winter months.

When to worry

It is normal for the plant to stretch slightly as it blooms, but if it flops over, it needs more light. This is rarely fatal but affects the plant's shape.

Stopping it coming back

Provide plenty of direct sunlight from the start to encourage compact, sturdy growth.

Questions people ask

Can I prune leggy stems?
Yes, trimming back the long stems will encourage the plant to branch out and grow bushier.
Will it recover if I move it to the sun?
The existing stems will not shrink, but new growth will be much tighter and healthier.
