- Check if the plant is leaning toward a window.
- Review your recent fertilizing schedule.
Likely causes
Insufficient Light
Most likelyHow to tell: The top of the cactus looks stretched or pale compared to the base. It is leaning toward the nearest window or light source.
What to do: Move the plant to a spot that gets at least 6 to 8 hours of direct, unfiltered sunlight. If you cannot provide enough sun, consider a high output grow light.
Too Much Fertilizer
PossibleHow to tell: The plant is growing rapidly but looks weak or thin. This often happens when the plant is pushed to grow faster than its light levels allow.
What to do: Stop fertilizing your cactus during the winter months. Only use a balanced cactus fertilizer once or twice during the peak summer growing season.

When to worry
Once a cactus has stretched, it will not return to its original round shape. You are mainly preventing further distortion.
Stopping it coming back
Provide as much direct sun as possible throughout the year. Avoid overfeeding, as cacti prefer a slow, steady growth pace.

Questions people ask
- Can I prune the stretched part off?
- No, pruning a cactus will leave a permanent scar and will not fix the shape. It is best to let it grow and ensure it gets better light from now on.
- Is a south facing window enough?
- A south facing window is usually perfect for a Golden Barrel Cactus. It provides the intense, direct light they need to stay compact.
