Dill · Anethum graveolens

Why is my dill showing signs of root rot?

It is less common for dill to get root rot if the soil drains well, but it happens when the roots sit in water for too long. Check the soil moisture and drainage holes in your pot first.

Check these first

  1. Feel the soil to see if it is soggy.
  2. Check the bottom of the pot for standing water.
  3. Smell the soil for a sour or rotten odor.

Likely causes

  1. Overwatering

    Possible

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

    What to do: Stop watering immediately and let the top 2 inches of soil dry out. If the pot has no drainage, repot the plant into a container with holes.

  2. Poor Drainage

    Possible

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

    What to do: Mix perlite or coarse sand into your potting soil to improve aeration. Ensure you are using a pot that allows excess water to escape freely.

When to worry

Root rot is serious and can kill the plant quickly if the roots are already black and mushy. If the plant is just slightly wilted, it may recover with better care.

Stopping it coming back

Only water when the top inch of soil feels dry and always use a well draining potting mix.

Questions people ask

Can I save a dill plant with root rot?
If the rot is caught early, you can trim away the mushy roots and repot the plant in fresh, dry soil. If the majority of the roots are black, it is usually too late.
How often should I water my dill to prevent rot?
Water every 3 to 5 days, but always check the soil first. If it still feels damp, wait another day before watering.
