Why is my Green alkanet suffering from root rot?

It is less common for Green alkanet to suffer from root rot unless the soil stays soggy for too long. Check the soil moisture levels and drainage immediately to see if the roots are drowning.

Check these first

  1. Feel the soil to see if it is waterlogged.
  2. Check if the plant is sitting in a low spot where water pools.
  3. Examine the roots for a foul smell or mushy texture.

Likely causes

  1. Poor Drainage

    Possible

    How to tell: The leaves will turn yellow or brown and the plant will look wilted even when the soil is wet. The roots will appear mushy and dark instead of firm and white.

    What to do: Stop watering immediately and allow the top 2 inches of soil to dry out. If the soil is heavy clay, amend it with compost or grit to improve drainage.

  2. Overwatering

    Possible

    How to tell: The plant shows signs of decline despite regular watering. The base of the stems may feel soft or show signs of decay.

    What to do: Adjust your watering schedule to every 5 to 7 days, ensuring the soil is moist but not waterlogged. If the plant is in a container, ensure it has holes at the bottom.

When to worry

If the stems are turning black at the base or the plant is collapsing, it is likely too late to save it. Minor yellowing can often be reversed by letting the soil dry out.

Stopping it coming back

Ensure your soil is well draining and never let the plant sit in standing water. Always check the soil moisture with your finger before adding more water.

Questions people ask

Can I save a plant with root rot?
If the damage is limited, you can trim away the mushy roots and repot the plant in fresh, well draining soil. If the majority of the root system is decayed, it is usually best to start over.
Does this plant need constant moisture?
It likes evenly moist soil, but that does not mean wet or swampy. Always allow for some airflow around the roots.
