Can I save a plant with root rot?

If only a few roots are affected, you can try to let the soil dry out completely. However, if the stem is already mushy, the plant will not recover.

How often should I water my snow peas?

Water every 2 to 4 days depending on the weather. Keep the soil evenly moist but never let it sit in standing water.

Snow pea: root rot, causes and fixes

Check these first

Check if the soil feels soggy or swampy to the touch.
Inspect the base of the stem for mushy or discolored tissue.
Dig down 3 inches to see if the roots look brown and slimy instead of firm and white.

Likely causes

Waterlogged Soil
Most likely
How to tell: The leaves turn yellow and wilt even when the soil feels wet. You might notice a sour smell coming from the base of the plant.
What to do: Stop watering immediately and let the top 2 inches of soil dry out. If the soil is heavy clay, mix in organic compost to improve drainage for future plantings.
Pythium Fungal Infection
Possible
How to tell: The stems near the soil line look dark and mushy. The plant stops growing suddenly and collapses.
What to do: Remove and discard the affected plants to prevent the fungus from spreading. Do not replant peas in that specific spot for at least 2 years.

When to worry

If the entire plant has collapsed and the stem is soft at the base, it is likely too late to save it. It is normal for older, lower leaves to yellow slightly as the plant finishes its harvest cycle.

Stopping it coming back

Plant your peas in raised beds or mounds to ensure water drains away from the roots. Always wait until the top inch of soil is dry before watering again.
