Why is my fringed willowherb growing so leggy?

A leggy fringed willowherb is usually reaching out for more light. Check your current light levels to see if the plant is getting enough bright indirect sun.

Check these first

  1. Assess how many hours of bright light the plant receives.
  2. Check if the plant is leaning toward a window.
  3. Look at the distance between the leaf nodes on the stem.

Likely causes

  1. Insufficient light

    Most likely

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

    What to do: Move the plant to a brighter location with more indirect light. If indoors, place it near a window that gets bright light for most of the day.

  2. Lack of pruning

    Possible

    How to tell: The plant is tall and sparse but otherwise healthy. It has not been trimmed back to encourage bushier growth.

    What to do: Pinch back the tips of the stems to encourage side branching. This will help the plant grow fuller rather than just taller.

When to worry

Worry if the stems are so weak they cannot support themselves. It is normal for the plant to stretch slightly during the darker winter months.

Stopping it coming back

Provide consistent bright light and pinch back the stems regularly to maintain a compact shape.

Questions people ask

Can I cut back the long stems?
Yes, trimming the stems will encourage the plant to grow new, stronger shoots from the base.
Will it grow back if I prune it hard?
Fringed willowherb responds well to pruning. It will grow back bushier as long as it has enough light.
