Variegated dogwood · Cornus alba 'Elegantissima'

Why is my variegated dogwood suffering from root rot?

Root rot is less common for this plant, usually caused by heavy, waterlogged soil that prevents roots from breathing. Check the soil moisture levels and drainage immediately to see if the roots are sitting in standing water.

Check these first

  1. Feel the soil 2 inches deep to check for excess moisture.
  2. Inspect the base of the trunk for soft or discolored bark.
  3. Check if the planting site has standing water after rainfall.

Likely causes

  1. Poor drainage

    Most likely

    How to tell: The soil stays soggy for days after watering and the plant looks wilted despite wet ground. You might notice a sour smell coming from the base of the plant.

    What to do: Improve the soil structure by mixing in organic compost or perlite to increase aeration. Ensure the planting site is not in a low spot where water collects after rain.

  2. Overwatering

    Possible

    How to tell: Leaves turn yellow or brown and drop prematurely while the stems feel soft. The root system will appear mushy or black instead of firm and white.

    What to do: Adjust your watering schedule to every 5 to 7 days, allowing the top 2 inches of soil to dry out slightly. Only water deeply during extended dry spells rather than on a rigid calendar.

When to worry

If the entire shrub is wilting and the stems are turning black, the damage may be too extensive to save. Minor yellowing is normal during the transition to autumn.

Stopping it coming back

Plant your dogwood in well draining soil and avoid watering if the ground is already saturated.

Questions people ask

Can I save a dogwood with root rot?
If you catch it early, you can improve drainage and reduce watering to help the plant recover. If the roots are completely black and mushy, the plant likely cannot be saved.
How often should I water my dogwood?
Water every 3 to 7 days depending on the weather. Always check the soil first to ensure it needs moisture before adding more.
