Pocket Botanist
Check these first
- Measure the amount of light the area receives.
- Check if nearby trees or shrubs have grown to block the sun.
- Look for signs of over fertilization.
Likely causes
Insufficient Light
Most likelyHow to tell: The stems are long and weak, and the leaves are spaced far apart. The plant may also lean heavily toward the nearest light source.
What to do: Move the plant to a spot with better partial shade. If it is in deep shade, consider trimming back overhanging branches to let in more light.
Excessive Nitrogen
PossibleHow to tell: The plant grows very fast with lush, soft stems that cannot support their own weight. This often happens if you over fertilize.
What to do: Stop all fertilization immediately. Goutweed is a vigorous grower and rarely needs extra food.

When to worry
It is not a health crisis, but it makes the plant look messy. If the stems are falling over, it is time to prune them back.
Stopping it coming back
Provide the right amount of partial shade and avoid adding fertilizer to the soil.
