Can I save a tree with root rot?

If caught early, you can save it by improving drainage and reducing your watering frequency. If the roots are black and mushy, the damage may be too severe to reverse.

Does mulch cause root rot?

Mulch is great for moisture retention, but keep it a few inches away from the trunk. Piling mulch against the bark can trap too much moisture and encourage rot.

White mulberry: root rot, causes and fixes

Check these first

Check the soil moisture level at a depth of 4 inches.
Inspect the area around the trunk for standing water.
Look for signs of yellowing or wilting leaves.

Likely causes

Poor soil drainage
Most likely
How to tell: The leaves may turn yellow or wilt even when the soil feels wet. You might also notice a sour smell coming from the base of the tree.
What to do: Improve the soil structure by mixing in organic matter like compost to help water move away from the roots. Avoid planting in low spots where water pools after rain.
Overwatering
Possible
How to tell: The tree shows stunted growth and the foliage looks pale or sickly. Dig a small hole near the roots to see if the soil is constantly saturated.
What to do: Wait until the top 3 to 4 inches of soil are dry before watering again. Stick to a schedule of every 7 to 14 days, providing a deep soak only when the ground is dry.

When to worry

If the tree begins to drop leaves prematurely or branches start to die back, the rot may be advanced. It is normal for a few lower leaves to yellow during extreme heat.

Stopping it coming back

Plant your mulberry in well draining soil and ensure it is not sitting in a depression that collects water.
