Parsley · Petroselinum crispum

Why is my parsley plant looking so leggy?

Leggy parsley is reaching out for more light. This happens when the plant does not get enough sun, causing the stems to stretch and weaken.

Check these first

  1. Assess the amount of direct sun the plant receives daily.
  2. Rotate the pot every few days to ensure even growth.
  3. Check the temperature in the plant's current location.

Likely causes

  1. Insufficient Light

    Most likely

    How to tell: Stems are long, thin, and leaning heavily toward the nearest window.

    What to do: Move your parsley to a spot that receives at least 6 hours of direct or bright indirect sunlight. If growing indoors, use a grow light to supplement natural light.

  2. High Temperatures

    Possible

    How to tell: The plant grows rapidly but looks spindly and weak during hot weather.

    What to do: Move the plant to a cooler location or provide afternoon shade. Keep the soil consistently moist to help the plant handle heat stress.

When to worry

Leggy growth is rarely fatal, but it makes the plant prone to falling over. It is a sign that the plant is not thriving in its current environment.

Stopping it coming back

Provide plenty of light and prune the plant regularly to encourage a bushier shape.

Questions people ask

Should I cut back leggy stems?
Yes, trimming back long stems will encourage the plant to grow thicker and bushier. Use clean scissors to snip the stems just above a leaf node.
Can I grow parsley in full shade?
Parsley prefers full sun to partial shade. In full shade, it will almost always become leggy and produce fewer leaves.
