Check these first
- Feel the soil depth with your finger to check for moisture.
- Inspect the base of the trunk for soft or discolored bark.
- Observe the drainage speed after a heavy rain or watering.
Likely causes
Poor soil drainage
Most likelyHow to tell: The soil feels soggy or swampy hours after watering, and the base of the trunk may look dark or soft. You might notice a sour smell coming from the dirt.
What to do: Stop watering immediately and allow the soil to dry out completely. If the soil is heavy clay, you may need to amend the area with organic matter or transplant the tree to a better location with sandy, well draining soil.
Overwatering
Most likelyHow to tell: The tree is being watered too frequently, preventing the roots from getting the oxygen they need. The foliage may look dull or start to wilt despite the wet soil.
What to do: Adjust your schedule to water only every 14 days once the tree is established. Ensure the soil is dry several inches down before you add more water.

When to worry
If the trunk bark is peeling away or soft to the touch, the rot may have reached the crown, which is often fatal. Some minor root stress is normal after heavy seasonal rains.
Stopping it coming back
Plant your madrone on a slight slope or in raised beds to ensure water moves away from the root zone. Never pile mulch directly against the trunk.
