Can I trim back leggy stems?

It is better to provide more light rather than trimming. Trimming can stress the plant and reduce your harvest.

Do leggy peas need support?

Yes, all snow peas need a trellis or netting to climb. Providing support helps them grow upright and prevents them from tangling.

Snow pea: leggy growth, causes and fixes

Check these first

Check if the plant is in a shaded area.
Look at the distance between the leaf nodes.
See if the plants are touching each other.

Likely causes

Lack of sunlight
Most likely
How to tell: The stems are long, thin, and pale with large gaps between the leaves. The plant is clearly stretching toward the nearest light source.
What to do: Move the plant to a location with full, direct sun. If growing indoors, use a grow light placed just a few inches above the top of the plant.
Crowding
Possible
How to tell: The plants are growing into each other and competing for light. This happens when seeds are sown too close together.
What to do: Thin out the seedlings so they have at least 3 to 4 inches of space between them. This improves airflow and light penetration for all plants.

When to worry

If the stems are so thin they cannot support their own weight, they may snap. It is normal for peas to grow tall, but they should have sturdy stems and dense foliage.

Stopping it coming back

Provide full sun from the moment the seeds sprout and thin them properly to ensure each plant gets enough light.
