Should I prune my leggy watercress?

Yes, trimming the long stems will encourage the plant to branch out and become fuller. Use clean scissors to cut just above a leaf node.

Will it recover if I move it to the sun?

Yes, but move it gradually over a few days to avoid leaf burn. It will start producing shorter, stronger stems in the new light.

Likely causes

Insufficient Light
Possible
How to tell: The stems stretch out and look thin with large gaps between the leaves. The plant will lean heavily toward the nearest light source.
What to do: Move the plant to a location with brighter, indirect light. If you are growing indoors, consider adding a grow light for 8 to 10 hours a day.
Excessive Heat
Possible
How to tell: The plant grows quickly but weakly, resulting in long, spindly stems. This often happens when the water temperature gets too warm for this cool-loving plant.
What to do: Keep the plant in a cooler area of your home or garden. Ensure the water remains fresh and cool by changing it every 1 to 2 days.
