Heavy rain followed by long period of drought can cause significant shifting in our soils. This can be concerning for trees that have shallow roots.

Heavy Rain Doesn’t Mean Tree Failure

Healthy trees  that are structurally sound are more resilient and designed to withstand significant environmental forces. 

Trees that already have underlying defects or have experienced substantial stress,  have root-related problems that were already developing are more at risk. 

Stressed Trees Are at More Risk From Tree Failure Post Heavy Rain

The combination of stressed trees with shallow roots, clay soils, wind, and heavy rain after prolonged drought conditions can lead to root plate failure due to shifting soil.

• Prolonged drought creates shrinkage in the soil.
• Heavy rain will expand the soil.
• Wet soil generally provides less resistance to root movement than firm soil.
• Saturated soil and strong winds may increase the possibility of the root plate shifting and the entire tree uprooting.

One of the biggest things to watch for is change.

If a tree suddenly looks different after a storm, particularly at the base or in its lean, that deserves attention, please reach out to us for an assessment.
