Refresh mulch rings
Mulch moderates soil, blocks weeds, and feeds fungi as it breaks down. Piled against a trunk keeps bark wet and invites voles and rot. Pull it back into a doughnut.
Steps
- Pull old mulch off the flare of every tree and shrub you can see.
- Top up to 2–3 inches of shredded hardwood or arborist chips.
- Keep a 3-inch bare collar around stems.
Tips
- Spring after soil warms, and a light fall top-up, beat one giant dump.
