Check these first
- Measure the hours of direct sun the plant receives.
- Check if the plant is shaded by other objects or plants.
- Rotate the pot to ensure all sides get even light.
Likely causes
Insufficient light
Most likelyHow to tell: The stems are long and thin with large gaps between the leaves.
What to do: Move the plant to a location that receives full, direct sun for at least 6 to 8 hours a day. If you are growing indoors, place it in your sunniest south facing window.
Overcrowding
PossibleHow to tell: The plant grows tall and thin because it is competing with nearby plants for light.
What to do: Give the plant more space by moving it away from other foliage. This allows light to reach the lower stems and encourages a fuller shape.

When to worry
Legginess is a sign of stress but is not an emergency. It is normal for the plant to stretch slightly as it prepares to flower.
Stopping it coming back
Keep the plant in a bright, sunny spot and rotate it weekly to ensure even growth.

Questions people ask

- Yes, trimming back long stems will encourage the plant to branch out and grow more compactly.
- Will it grow back if I cut it?
