Likely causes
Poor soil drainage
Most likelyHow to tell: The tree shows stunted growth and yellowing leaves while the soil remains soggy for days after rain. The roots may appear mushy or dark if you can inspect them.
What to do: Improve the soil drainage by amending the surrounding area with organic matter. If the tree is in a low spot, consider installing a drainage pipe or building a raised berm.
Overwatering
PossibleHow to tell: The tree is watered too frequently, preventing the roots from getting oxygen. The foliage may wilt even though the ground is wet.
What to do: Adjust your watering schedule to every 7 to 14 days. Ensure the soil dries out slightly between waterings to allow the roots to breathe.

When to worry
Root rot is a serious condition that can kill a tree if left untreated. If the tree is leaning or the trunk base is soft, it may be too late to save.
Stopping it coming back
Plant the tree in a well draining location and avoid piling mulch directly against the trunk. Only water when the top few inches of soil feel dry.

Questions people ask
- Can I treat root rot with fungicide?
- Fungicides are rarely effective for established root rot. The best approach is to fix the drainage and manage the moisture levels.
- How do I know if my soil drains well enough?
- Dig a hole 12 inches deep and fill it with water. If it takes more than 24 hours to drain, your soil is likely too heavy for this tree.
