Can I save a wisteria with root rot?

You can save it if you catch it early. Trim the rotted roots and move the plant to a drier, better draining environment.

Japanese wisteria: root rot, causes and fixes

Check these first

Smell the soil for a sour or rotten odor.
Examine the roots to see if they are firm or mushy.
Check if the pot has adequate drainage holes.

Likely causes

Overwatering
Most likely
How to tell: The leaves turn yellow and wilt even though the soil is wet. The roots appear mushy and dark instead of firm and white.
What to do: Stop watering immediately and let the top 2 inches of soil dry out. If the rot is severe, repot the plant into fresh, well draining soil and trim away the dead roots.
Poor drainage
Possible
How to tell: Water pools on the surface of the soil for a long time after watering. The base of the stem may look soft or discolored.
What to do: Ensure the pot has large drainage holes at the bottom. If planting in the ground, amend the soil with organic matter to improve aeration.

When to worry

Stopping it coming back

Always check that the soil is moist but not waterlogged before adding more water.
