Can I save a buckthorn with root rot?

If you catch it early, you can save it by pruning away the damaged roots and repotting in fresh, dry soil. If the rot has spread to the main stem, it is usually too late.

How often should I water my buckthorn?

Once established, it is very drought tolerant. Water every 7 to 14 days depending on the heat and rainfall.

Common buckthorn: root rot, causes and fixes

Check these first

Check the soil moisture level by sticking your finger 2 inches deep.
Inspect the drainage holes to ensure they are not blocked.
Smell the soil for any signs of decay or rot.

Likely causes

Poor drainage
Most likely
How to tell: The soil remains wet long after watering and the base of the stem feels soft or mushy. You might also notice a sour smell coming from the soil.
What to do: Improve the soil structure by mixing in organic matter or grit to help water drain away. If the plant is in a container, ensure it has drainage holes and move it to a spot with better airflow.
Overwatering
Possible
How to tell: Leaves start to yellow and wilt even though the soil is constantly damp. The plant stops growing and looks generally unhappy.
What to do: Wait until the top 2 to 3 inches of soil are dry before you water again. Adjust your schedule to every 10 to 14 days rather than weekly if the soil stays wet.

When to worry

If the stem base is black and mushy, the rot has likely reached the crown and the plant may not recover. Some minor yellowing is normal during seasonal transitions.

Stopping it coming back

Only water when the top few inches of soil feel dry to the touch. Ensure the shrub is planted in well draining soil to prevent water from pooling around the roots.
