Check these first

- Check if nearby shrubs or trees are casting shade on the plant.
- Review your recent fertilizing schedule.
Likely causes
Insufficient light
PossibleHow to tell: The grassy leaves will look thin, pale, and reach upward or outward rather than forming a dense cushion. You might also notice the plant failing to produce its signature globe flowers.
What to do: Move your plant to a location that receives at least 6 to 8 hours of direct sun daily. If it is in a container, shift it to the sunniest spot on your patio.
Excessive fertilizer
PossibleHow to tell: The plant grows too quickly, resulting in soft, floppy foliage that loses its compact shape. This often happens if you use a high nitrogen fertilizer.
What to do: Stop fertilizing immediately, as Sea Thrift prefers lean, rocky soil. If the soil is very rich, you may need to mix in some sand or grit to reduce the nutrient density.

When to worry
It is time to act if the plant looks weak and is starting to flop over in the center. A little bit of growth after a heavy rain is normal, but constant stretching is a sign of a light deficiency.
Stopping it coming back
Ensure your Sea Thrift is planted in full sun and avoid adding compost or fertilizer to the soil, as this plant thrives in poor, sandy conditions.

Questions people ask
- Will my plant bloom if it is leggy?
- Likely not. Leggy plants are stressed and usually lack the energy required to produce their flower stalks.
- Can I trim back the leggy growth?
- Yes, you can trim the foliage to tidy up the mound. However, the plant will continue to stretch until it gets enough light.
