Red Osier Dogwood · Cornus sericea

Why is my Red Osier Dogwood showing signs of root rot?

It is less common for this plant to get root rot unless it is planted in heavy, poorly draining clay soil that stays soggy. Check the soil drainage and moisture levels near the base of the plant first.

Check these first

  1. Feel the soil to see if it is waterlogged.
  2. Check if the planting site sits in a low spot where water pools.
  3. Smell the soil for any signs of decay.

Likely causes

  1. Poor soil drainage

    Possible

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

    What to do: Stop watering immediately to let the soil dry out. If the soil is heavy clay, consider transplanting to a spot with better drainage or amending the soil with organic compost.

  2. Overwatering

    Possible

    How to tell: The leaves turn yellow and drop while the soil remains consistently wet. The stems near the soil line may appear soft or discolored.

    What to do: Adjust your watering schedule to every 7 to 14 days depending on the weather. Ensure the top 2 inches of soil dry out slightly before you add more water.

When to worry

If the stems are turning black or mushy at the base, the damage may be too far gone to save the plant. Minor yellowing can often be reversed by correcting the moisture levels.

Stopping it coming back

Plant your dogwood in well draining soil and avoid creating a depression around the base that collects water.
