Check these first
- Observe how many hours of direct sun the plant gets.
- Check if the plant is leaning toward a window.
- Look at the color of the new leaves.
Likely causes
Insufficient Light
Most likelyHow to tell: The leaves are long, thin, and pale instead of thick and sturdy. The plant is leaning 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 sunlight daily. If you are growing it indoors, a south facing window is best.
Excessive Fertilizer
PossibleHow to tell: The plant is growing very fast but the new leaves are weak and floppy.
What to do: Stop fertilizing for the rest of the season. Century plants are slow growers and do not need much food.

When to worry
Legginess is not fatal, but it makes the plant structurally weak. It is normal for the plant to grow slowly, but it should never look stretched.
Stopping it coming back
Keep your plant in the brightest spot you have, preferably outdoors in full sun during the summer.

Questions people ask
- Will my leggy plant return to its normal shape?
- Existing leggy leaves will not shrink back, but new growth will be compact if you provide enough light. You can prune away the weakest leaves once the plant is healthy.
- Can I use a grow light?
- Yes, if you do not have a sunny window, a high output LED grow light can help prevent legginess.
