Pocket Botanist
Check these first
- Measure the hours of direct sunlight the plant receives.
- Check if nearby plants or structures are casting shade.
- Review your recent fertilizer application schedule.
Likely causes
Insufficient Light
Most likelyHow to tell: The stems are long, thin, and reaching toward the nearest light source with large gaps between leaves. The plant looks sparse rather than bushy.
What to do: Move your pot to a spot that receives at least 6 to 8 hours of direct sunlight daily. If you cannot provide enough natural light, consider using a high output grow light.
Excessive Nitrogen Fertilizer
PossibleHow to tell: This is less common for this plant, but too much nitrogen often causes rapid, weak stem growth. You will see lush green foliage that cannot support its own weight.
What to do: Stop fertilizing for the rest of the season. Flush the soil with plenty of water to wash out excess salts and allow the plant to stabilize.

When to worry
It is time to worry if the stems are so weak they are collapsing under their own weight. Minor stretching is normal during cloudy winter months.
Stopping it coming back
Keep your plant in a full sun location and avoid overfeeding with nitrogen heavy fertilizers.

Questions people ask
- Can I prune back leggy stems?
- Yes, you can trim back long stems to encourage a bushier shape. Make your cuts just above a leaf node to promote new growth.
- Will the stems thicken up if I move it?
- Existing stems will not thicken significantly, but new growth will be much sturdier. The plant will look better as it fills in with healthy foliage.
