Likely causes
Insufficient light
PossibleHow to tell: The stalks will be thin and the distance between the nodes will be unusually long. The plant may also lean heavily toward the nearest light source.
What to do: Move your bamboo to a spot that receives bright, indirect light or partial sun. If growing indoors, consider a grow light to supplement the natural light.
Improper fertilization
PossibleHow to tell: The plant grows quickly but the stalks remain weak and spindly. This often happens if you use too much nitrogen without enough light to support the growth.
What to do: Switch to a balanced fertilizer during the growing season. Reduce the frequency of feeding to once every 4 to 6 weeks.

When to worry
Worry if the stalks are so weak they cannot stand upright on their own. It is normal for young bamboo to grow quickly in spring, which can sometimes look a bit stretched.
Stopping it coming back
Provide consistent bright light throughout the year to keep the growth compact and strong. Rotate your pot occasionally to ensure even light exposure.
