Leaning Ash Tree: 5 Degrees Is Normal, Not a Hazard

Your 50-ft ash leans 5° east, heavy limbs east, saturated soil. Will it fall on garage?

Assessment

• Most trees have some lean; 5° is negligible.
• Root spread = 1.5× canopy width; anchors well even with lean.
• Saturated soil reduces friction, but ash roots are extensive.

When to Worry

• Lean >30° + soil heaving/mounding on opposite side.
• Cracks in trunk, major deadwood, fungal conks.

Action

• No action needed. Monitor annually.
• If concerned, hire ISA Certified Arborist for formal risk assessment.

Bottom Line

5° lean on a mature ash in saturated soil is normal. Not a hazard. Sleep easy.
