redroot pigweed · Amaranthus retroflexus

Why is my redroot pigweed wilting?

It is less common for this plant to get root rot unless the soil stays soggy for too long. Check the soil moisture level and the smell of the roots to see if they are decaying.

Check these first

  1. Feel the soil to see if it feels swampy or waterlogged.
  2. Check the drainage holes to ensure they are not blocked.
  3. Gently pull the plant out to inspect the roots for a foul smell.

Likely causes

  1. Overwatering

    Possible

    How to tell: The leaves will turn yellow and droop even though the soil is wet. The roots will look brown and mushy instead of firm and white.

    What to do: Stop watering immediately and let the top 2 inches of soil dry out. If the roots are badly damaged, trim the mushy parts and repot in fresh, well draining soil.

  2. Poor Drainage

    Possible

    How to tell: Water sits on the surface of the soil for a long time after watering. The plant looks stunted and unhappy despite your care.

    What to do: Ensure your pot has drainage holes at the bottom. Mix in some perlite or sand to improve the soil structure and allow excess water to escape.

When to worry

If the base of the stem feels soft or mushy, the rot has likely spread too far. If the leaves are just slightly drooping, you can usually save it by adjusting your watering.

Stopping it coming back

Only water when the top inch of soil feels dry and always empty the saucer under the pot after watering.

Questions people ask

How often should I water to avoid this?
Aim for every 3 to 7 days, but always check the soil first. If it is still damp, wait another day or two.
Can I save a plant with mushy roots?
Yes, if you catch it early. Trim away the dead roots, wash the remaining healthy ones, and repot in dry soil.
