Done right, mulch holds moisture, steadies soil temperature, blocks weeds and protects roots. Done wrong — piled against the trunk — the same mulch traps moisture, rots bark, invites pests and grows girdling roots that strangle the tree.
The sheet shows the donut (2–4 inches deep, a 3–6 inch gap at the trunk, spread out toward the drip line) versus the volcano, with a refresh-don't-pile reminder to rake and check depth before adding more. A clean homeowner leave-behind for pros.
