How do I fix root rot on my garden pea?

It is less common for garden peas to get root rot unless they are sitting in waterlogged soil for too long. Check your drainage and watering habits immediately.

Check these first

  1. Check if the soil is soggy or waterlogged.
  2. Inspect the drainage holes in your container.
  3. Smell the soil for a foul, swampy odor.

Likely causes

  1. Poor drainage

    Most likely

    How to tell: The leaves turn yellow and the plant wilts even when the soil is wet. The roots will look brown, mushy, and smell bad.

    What to do: Stop watering immediately and let the soil dry out. If in a pot, ensure the drainage holes are not blocked and use a well-draining potting mix.

  2. Overwatering

    Possible

    How to tell: The soil stays constantly soggy and the plant growth is stunted. You may see mold growing on the surface of the soil.

    What to do: Adjust your watering schedule to every 2 to 4 days, checking that the top inch of soil is dry before adding more water. Improve airflow around the base of the plant.

When to worry

If the roots are black and mushy, the plant is likely beyond saving. If the roots are still firm and white, you can save the plant by correcting the moisture.

Stopping it coming back

Always use a light, airy soil mix and never let your pea plants sit in a saucer of standing water.

Questions people ask

Can I save a plant with root rot?
If caught early, you can repot the plant into fresh, dry soil and trim away the mushy roots. If the damage is extensive, it is best to start over.
How do I know if my soil drains well enough?
Water should soak into the soil within a few seconds. If it pools on top, your soil is too heavy and needs more perlite or compost.
