Keep mulch 12 to 18 inches away from the trunk for any size tree. Mulch should not be stacked against the trunk (top) because roots can grow there (below) and surround the trunk. Simply spread 2 to 3 inches of mulch evenly around the tree and leave a few inches around the tree trunk to expose the bell-shaped root. Make sure that no mulch touches the trunk itself.
The ideal is to mulch up to the drip line of a tree. Trees, especially younger trees, tend to benefit more from a 2- to 3-inch layer of mulch around their base. However, for the first 12 inches that immediately surround the trunk, dilute the layer of mulch so that it covers the soil. This will avoid common problems associated with excessive use of mulch.
Mulch should never touch the tree trunk. The mulch should only be 2 to 3 inches deep around the tree. Keep the mulch 1 to 2 inches away from the trunk. And extend the mulch ring a minimum of 2 to 3 feet around the tree (the drip line is preferred).
When spreading mulch around trees, try to place at least 3 to 4 inches of mulch (up to 6 inches is fine). In flower beds and orchards, approximately 2 to 3 inches of mulch is usually sufficient (but opt for composted wood chips, rather than fresh or with a different type of organic mulch). The mulch should be at least 5 inches from the tree trunk and should cover the entire trunk. We recommend extending it as wide as the top of the tree, but you can make it as wide as you want or a little thinner.
The roots of a sapling are not as widespread, so you're likely to cover it well in a circle of mulch a few feet in diameter. A thinner layer of mulch over a larger area is much better than a mulch volcano for the health and longevity of the tree. A mulch volcano is often the result of people building circular raised beds around their trees and then filling raised beds with mulch. Unfortunately, many people think that having a lot of mulch is good, so they create a mulch volcano around the base of the tree instead of spreading it over the root system.
Let's take a look at the advantages and disadvantages of placing mulch around shrubs and trees, as well as the appropriate ways to apply mulch. A thicker layer of mulch is probably not a problem as long as the mulch is separated from the trunk. In fact, it's OK to not have any mulch right next to the tree trunk and gradually increase the depth of the mulch layer as you move toward the drip line. If you're late to mulch and can't pull out the weeds, cut them as low as you can and then mulch them.
Arborist wood chip mulch includes bark, wood and leaves (as opposed to bark mulch or mulch made from recycled hardwoods or pallets, for example). Inadequate mulching, such as a mulch volcano, can be fatal to the tree because of the risk of excess moisture entering the bark of the tree trunk.
