Why is my Carolina cranesbill growing so tall and thin?

A leggy plant is usually reaching for more light. Since this plant loves full sun, check if it is getting enough direct rays throughout the day.

Check these first

  1. Measure the hours of direct sunlight the plant receives.
  2. Check if nearby plants are shading your cranesbill.
  3. Look for signs of recent heavy fertilizer use.

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 light source.

    What to do: Move the plant to a spot that receives at least 6 to 8 hours of direct sun. If it is in a container, rotate it every few days to keep growth even.

  2. Excessive Nitrogen

    Possible

    How to tell: The plant grows very fast but the stems are soft and floppy. This often happens if you use a high nitrogen fertilizer.

    What to do: Stop fertilizing for the rest of the season. Switch to a balanced, slow release fertilizer only if the soil is very poor.

When to worry

It is a problem if the plant cannot support its own weight. It is normal for the plant to stretch slightly as it reaches the end of its life cycle.

Stopping it coming back

Ensure the plant gets full sun and avoid overfeeding with nitrogen rich products.
