Quick answer: Cambria Tree Care Blog — Mulch is the cheapest thing that happens to a tree: a flat layer over the root zone holds moisture through the dry season, keeps the soil temperature steady and feeds the soil life the tree depends on. Almost every mulch problem is a depth problem or a contact problem — too thick, or piled against the trunk where the bark has to stay dry.

  • Typical depth: Two to four inches, flat, from the drip line inward — never a cone against the trunk.
  • Typical timing: After planting or after a clean-up; refreshed in autumn so winter rain carries it down.
  • What it involves: Keeping the root flare visible, keeping mulch off the bark, and choosing material that breaks down rather than mats.
  • The standard: ISA and university extension guidance on arboricultural mulching and the root flare.

Field note. What we see most on this coast is not too little mulch but too much, in the wrong place: the volcano against the trunk that keeps the bark wet through the fog season and invites rot where the tree cannot show it until the canopy thins.

On the other hand, a thin ring of the wrong material is worse than none at all — matted, water-repellent mulch sheds the rain it was meant to store.
