Could my Bur oak have root rot? Causes and fixes

Check these first

Feel the soil moisture at the base of the tree.
Check for standing water after rain.
Look for yellowing leaves or canopy thinning.

Likely causes

Poor soil drainage
Most likely
How to tell: The tree shows yellowing leaves and general decline. The soil remains wet for days after rain or irrigation.
What to do: Improve drainage by aerating the soil or creating a slight slope away from the trunk. Reduce your watering frequency to allow the top 4 inches of soil to dry out.
Overwatering
Possible
How to tell: The leaves wilt even when the soil is wet. You may notice a musty or rotten smell coming from the soil surface.
What to do: Stop watering immediately and let the soil dry out. Check your irrigation system to ensure it is not running more than once every 14 days.

When to worry

Worry if the tree shows signs of crown dieback or if the bark near the base feels soft and spongy. This is a serious condition that can be fatal if not addressed early.

Stopping it coming back

Ensure the tree is planted in well draining soil and never water directly against the trunk. Always check the soil moisture before adding more water.
