Apply a layer of 2 to 4 inches of organic mulch and no more; use less if the soil is poorly drained. More than 4 inches can damage the tree's root system. If you use fine-textured mulch or mulch twice, use 1 to 2 inches, as these materials allow less oxygen to pass to the root area. 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). At a minimum, you should have a minimum 2-inch layer of mulch. Try not to exceed 6 inches deep or you may encounter the problems we mentioned above. A 2-inch layer doesn't seem like much, but it's enough to start taking advantage of the many benefits of mulch.
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). If you're late to mulch and can't pull out the weeds, cut them as low as you can and then mulch them.
But what is the right amount of mulch to use? Should you stack it around the tree to create a “mulch volcano”? Does it matter where you place the mulch? And is it really worth it? 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. A thicker layer of mulch is probably not a problem as long as the mulch is separated from the trunk. 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. Arborist wood chip mulch includes bark, wood and leaves (as opposed to bark mulch or mulch made from recycled hardwoods or pallets, for example).
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. 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.
