Mulch is a newly planted tree’s best friend because it:
Insulates the soil, helping to provide a buffer from heat and cold.
Retains water to help the roots stay moist.
Keeps weeds out to avoid root competition.
Prevents soil compaction.
Reduces lawn mower damage.
Steps to Adding Mulch Around Your Tree
Remove any grass within a 3-foot area (up to 10 feet for larger tree).
Pour natural mulch such as wood chips or bark pieces 2 to 4 inches deep within the circle.
Keep the mulch from touching the trunk of the tree.
