Viburnum

Is my viburnum suffering from root rot?

It is less common for a viburnum to develop root rot unless the soil stays soggy for too long. Check the soil moisture levels and drainage immediately to see if the roots are drowning.

Check these first

  1. Feel the soil an inch down to see if it is saturated.
  2. Inspect the base of the plant for any signs of standing water.
  3. Check the roots for a mushy texture or dark color if you can reach them.

Likely causes

  1. Poor Drainage

    Most likely

    How to tell: The leaves are yellowing and wilting even though the soil feels wet. You might notice a sour smell coming from the base of the plant.

    What to do: Improve soil drainage by mixing in organic matter like compost. If the plant is in a pot, ensure it has drainage holes and stop watering until the top inch of soil is dry.

  2. Overwatering

    Possible

    How to tell: The soil remains constantly damp and the plant shows signs of stress like drooping leaves. This prevents oxygen from reaching the roots.

    What to do: Wait until the top inch of soil is dry before watering again. Stick to a schedule of every 7 to 14 days depending on your local weather.

When to worry

If the leaves are turning brown and brittle while the soil is wet, the root system may be severely damaged. This is a serious condition that requires immediate action.

Stopping it coming back

Ensure your viburnum is planted in well draining soil and never let it sit in a saucer of water.

Questions people ask

Can I save a plant with root rot?
If caught early, you can save it by letting the soil dry out and improving drainage. If the roots are black and mushy, the plant may be too far gone.
How often should I water my viburnum?
Water deeply every 7 to 14 days, but only when the top inch of soil is dry. Always check the soil before adding more water.
