Check these first
- Observe the distance between the leaves on the stems.
- Check if the plant is leaning toward a window.
- Measure the temperature near the plant.
Likely causes
Insufficient light
Most likelyHow to tell: The stems grow long and thin with large gaps between the leaves. The plant leans heavily toward the nearest light source.
What to do: Move the pot to a spot with brighter indirect light. If you are growing it indoors, place it within 2 feet of a window that gets filtered morning sun.
High temperatures
PossibleHow to tell: This is less common for this plant, but heat stress makes it grow rapidly and weakly. It usually happens when the plant is kept in a room above 75 degrees Fahrenheit.
What to do: Relocate the plant to a cooler area of your home. Keep it away from heating vents or radiators that dry out the air and increase ambient heat.

When to worry
It is normal for the plant to stretch slightly during the darker winter months. Worry only if the stems become so weak they cannot support their own weight.
Stopping it coming back
Provide consistent bright indirect light throughout the growing season to keep growth compact.

Questions people ask
- Can I prune back the long stems?
- Yes, you can trim back leggy stems to encourage bushier growth. Use clean scissors to snip just above a leaf node.
- Will it bloom if it is leggy?
- A leggy plant often lacks the energy to produce flowers. Improving the light quality is the best way to help it bloom again.
