Why is my Barren brome growing so leggy?

A leggy Barren brome is typically reaching for more light. This plant needs full sun to maintain a compact and sturdy shape.

Check these first

  1. Measure the hours of direct sun the plant gets.
  2. Check if the plant is leaning toward a window or light source.
  3. Recall if you have added fertilizer recently.

Likely causes

  1. Lack of Sunlight

    Most likely

    How to tell: The stems are long, thin, and leaning toward the nearest light source. The plant looks sparse rather than bushy.

    What to do: Relocate the plant to a spot with full, direct sun. If it is in a container, rotate it every few days to ensure even growth.

  2. Excessive Fertilizer

    Possible

    How to tell: The plant is growing very fast but the stems are weak and floppy. The foliage is a very dark green.

    What to do: Stop fertilizing immediately. Barren brome thrives in poor soil and does not need extra nutrients to stay healthy.

When to worry

Worry if the stems become so weak they cannot stand up on their own. Some stretching is normal during early spring growth.

Stopping it coming back

Give your brome as much direct sun as possible. Avoid adding any fertilizer to the soil.

Questions people ask

Can I prune it to make it bushier?
You can trim back the long stems to encourage a more compact look. However, the plant will still need more light to stop the legginess from returning.
Will it recover if I move it to the sun?
Yes, it will start growing stronger, sturdier stems once it gets enough light. The old leggy stems will remain, but you can trim them away once new growth appears.
