Check these first
- Measure the hours of direct sun the spot gets.
- Check if nearby plants are blocking the light.
- Count the distance between your plants.
Likely causes
Insufficient Light
Most likelyHow to tell: The stems are thin, pale, and stretching toward the nearest light source.
What to do: Ensure the plants receive full sun for at least 6 to 8 hours a day. If they are shaded, consider moving them or thinning out nearby plants.
Overcrowding
PossibleHow to tell: Plants are growing tall and thin because they are competing for light and space.
What to do: Thin your seedlings to a distance of 4 to 6 inches apart. This gives each plant enough room to develop properly.

When to worry
Worry if the stems are so weak they cannot stand up on their own. It is normal for seedlings to grow quickly in early spring.
Stopping it coming back
Plant in a location that receives full sun all day and thin seedlings early.
