Can I trim back leggy stems?

Yes, you can trim them, but the plant will likely keep stretching if the light remains low. It is better to move the plant to a brighter area.

Does leggy growth mean it is dying?

Not necessarily, but it does mean the plant is stressed. It is a sign that it is not getting the environment it needs to thrive.

Hairy bittercress: leggy growth, causes and fixes

Check these first

Assess the light levels in the current location.
Check if the plant is leaning toward a light source.
Examine the spacing between individual plants.

Likely causes

Insufficient Light
Most likely
How to tell: The stems are long and thin with large gaps between the leaves. The plant looks like it is leaning toward the nearest window.
What to do: Move the plant to a spot with brighter, indirect light. If you are growing it indoors, place it within 1 to 2 feet of a sunny window.
Crowding
Possible
How to tell: Multiple plants are growing in a small container and competing for resources. The stems become spindly as they push past each other.
What to do: Thin out the seedlings so each plant has at least 2 inches of space. This allows better airflow and light penetration to the base.
