- Inspect the plant for any signs of new growth that might be stunted.
Likely causes
Insufficient Light
Most likelyHow to tell: The stems are elongated with large gaps between the leaves, and the plant leans toward the nearest light source.
What to do: Move your plant to a spot that receives at least 6 hours of bright, indirect light or partial sun. If it is indoors, place it directly in a south or west facing window.
Lack of Pruning
Most likelyHow to tell: The plant has grown very tall and spindly without any branching, making it look thin and weak.
What to do: Trim the long, leggy stems back by one third to encourage fuller, bushier growth. Use sharp, clean shears and wear thick gloves to protect yourself from the thorns.

When to worry
It is normal for this plant to grow rapidly in spring, but if the growth is weak and floppy, it needs more light. You should worry if the stems become so thin they cannot support their own weight.
Stopping it coming back
Provide consistent, bright light and prune the plant annually to maintain a compact shape.
