Pocket Botanist
Check these first
- Assess the amount of direct sunlight the plant receives.
- Observe if the stems are leaning toward a window.
- Check if the plant has outgrown its current container.
Likely causes
Insufficient light
Most likelyHow to tell: The stems grow long, thin, and lean toward the nearest light source. They may also lose their compact, upright habit.
What to do: Move the plant to a window with direct sun exposure. If natural light is limited, place it under a high output grow light for 10 to 12 hours daily. Rotate the pot weekly to ensure even growth.
Overcrowding
PossibleHow to tell: The plant becomes very dense and individual stems start to stretch to compete for space and light. This often happens in small, crowded containers.
What to do: Divide the plant into smaller clumps during the spring. Repot them into fresh, moisture retentive soil. Give each new plant enough space to receive light on all sides.

When to worry
Worry if the stems become so weak they flop over completely. It is normal for the plant to have a slightly looser habit as it matures in lower light conditions.
Stopping it coming back
Provide as much direct sun as possible to keep the growth tight and upright.
