Why Winter Is the Best Time for Tree Inspections in Napa Valley

November 20, 2025

Winter may seem like a quiet season for trees, but it’s actually the ideal time to assess their health. Napa Valley’s rainy, windy winter months reveal structural issues and hidden damage that aren’t obvious during the rest of the year. At Mike’s Tree Service, we recommend winter inspections to keep your trees safe, stable, and ready for spring growth.



Here’s why this season matters most.

Winter Weather Reveals Structural Weaknesses

Wind, rain, and saturated soil put stress on tree limbs and root systems.
If a tree has internal decay, storm damage, or weak branch unions, winter conditions make those issues visible.


Signs we look for include:



  • Cracks

  • Leaning trunks

  • Dead or hollow branches

  • Root instability

No Leaves Make Tree Defects Easier to Spot

With foliage gone, arborists can clearly evaluate:



  • Branch structure

  • Deadwood

  • Overextended limbs

  • Crowded or crossing branches

This makes winter the most accurate season for inspections.

Preventative Pruning Is Safer and More Effective in Winter

Winter pruning offers major benefits:


  • Lower risk of disease transmission

  • Less stress on the tree

  • Improved spring growth

This is especially important for Napa’s ornamental and fruit-bearing species.

Protect Your Property Before Storm Season Peaks

Napa’s most intense winter storms often hit between December and March.


A winter inspection allows you to:


  • Identify hazards

  • Remove dangerous limbs

  • Prevent emergency removals

  • Protect structures, vehicles, and power lines
