Groundsel · Senecio peregrinus

Why is my Groundsel growing so tall and thin?

A leggy Senecio is usually reaching out for more light. When this plant does not get enough sun, it stretches its stems to find a brighter spot. Check if your plant is getting enough bright, indirect light first.

Check these first

  1. Observe the distance between the leaves on the stem.
  2. Check how many hours of bright light the plant receives daily.
  3. Rotate the pot every week to ensure even growth.

Likely causes

  1. Insufficient light

    Most likely

    How to tell: The stems are long with large gaps between the leaves. The plant leans heavily toward the nearest window.

    What to do: Move the plant to a brighter location, such as a south or west facing window. If you cannot provide enough natural light, consider using a grow light for 8 to 10 hours a day.

  2. Lack of pruning

    Possible

    How to tell: The plant is healthy but has become long and unruly over time. It is not necessarily sick, just overgrown.

    What to do: Prune back the long stems to encourage bushier growth. You can propagate the cuttings to start new plants.

When to worry

Legginess is rarely a sign of a dying plant, but it does mean the plant is not thriving. It is a cosmetic issue that you can fix with better light and pruning.

Stopping it coming back

Place your Senecio in a spot with plenty of bright, indirect light. Rotate the pot regularly to keep the growth balanced and compact.

Questions people ask

Can I cut the long stems off?
Yes, pruning is great for the plant. It will often branch out from the cut point, making the plant look fuller.
Will the stems grow back to normal?
No, the stretched parts will stay that way. You should prune them and let new, compact growth take over.
