Why is my Deptford pink looking so leggy?

When your Deptford pink starts stretching out and looking thin, it is usually begging for more sunlight. Check your light levels first to see if it is getting enough direct sun.

Check these first

  1. Move the plant to a brighter location.
  2. Check if the plant is leaning toward a light source.
  3. Assess if the plant is getting at least 6 hours of direct sun.

Likely causes

  1. Insufficient Light

    Most likely

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

    What to do: Move your plant to a spot that receives at least 6 to 8 hours of direct sun daily. If you are growing indoors, place it in a south facing window or use a strong grow light.

  2. Excessive Nitrogen

    Possible

    How to tell: This is less common for this plant, usually caused by over fertilizing with high nitrogen products. The plant grows quickly but the stems remain soft and floppy.

    What to do: Stop using high nitrogen fertilizers immediately. Switch to a balanced, low strength fertilizer once in the spring to encourage sturdier growth.

When to worry

It is time to worry if the stems are so weak they cannot support their own weight. Some stretching is normal if the plant is transitioning from a nursery to your home.

Stopping it coming back

Keep your Deptford pink in a spot with full, direct sun throughout the day.

Questions people ask

Can I prune back leggy stems?
Yes, you can trim back the long stems to encourage bushier growth. Just make sure you provide more light afterward so it does not grow back the same way.
Will my plant recover its shape?
It will start growing more compactly once it gets enough light. The old, stretched stems will not shrink, so you may want to prune them to help the plant look better.
