English Holly · Ilex aquifolium

Why is my English Holly showing signs of root rot?

It is less common for an English Holly to develop root rot, as this is usually caused by planting in heavy, clay soil that holds too much water. Check the soil drainage immediately to see if water is pooling around the base.

Check these first

  1. Feel the soil moisture at a depth of 2 inches.
  2. Observe if water pools around the base of the plant.
  3. Check for a foul, swampy smell coming from the soil.

Likely causes

  1. Poor Soil Drainage

    Most likely

    How to tell: The leaves turn yellow or brown and drop while the soil remains soggy for days after watering.

    What to do: Amend the soil with organic matter like compost to improve drainage. If the soil is heavy clay, consider replanting the holly in a raised bed.

  2. Overwatering

    Possible

    How to tell: The foliage wilts even when the soil feels wet to the touch.

    What to do: Wait until the top inch of soil is dry before watering again. Ensure your watering schedule does not exceed once every 7 to 14 days.
