How do I know if my elderberry has root rot?

It is less common for an elderberry to get root rot unless it is sitting in heavy, waterlogged soil. Check the drainage of your pot or garden bed first to ensure water is not pooling around the roots.

Check these first

  1. Smell the soil for a foul or rotting odor.
  2. Check if the pot has drainage holes that are not blocked.
  3. Gently inspect the roots to see if they are soft or mushy.

Likely causes

  1. Poor drainage

    Most likely

    How to tell: The soil stays soggy for days after watering and the plant looks yellow or wilted. You might notice a sour or swampy smell coming from the soil.

    What to do: Repot the plant into a container with drainage holes using a well draining soil mix. If in the ground, amend the soil with compost to improve drainage.

  2. Overwatering

    Possible

    How to tell: The leaves turn yellow and drop while the soil remains constantly wet. The roots appear mushy or black instead of firm and white.

    What to do: Allow the top 2 to 3 inches of soil to dry out completely between waterings. Reduce your watering frequency to every 10 to 14 days during cooler months.

When to worry

If the roots are black and slimy, the plant is in critical condition and may not recover. It is normal for the soil to be damp immediately after a thorough watering.

Stopping it coming back

Always use a well draining soil mix and never let the plant sit in a saucer of standing water.

Questions people ask

Can I save a plant with root rot?
You can try by trimming away the mushy roots and repotting in fresh, dry soil. Success depends on how much healthy root system remains.
How often should I water to avoid rot?
Water only when the top few inches of soil feel dry. This usually happens every 7 to 14 days depending on your home's temperature.
