When applied properly, mulch can greatly benefit your trees by:
- Controlling weeds and grass
- Maintaining moisture in the soil and keeping your tree hydrated
- Protecting the roots and trunk from mowers and other lawn maintenance tools
Here are a few simple tips to keep in mind when mulching your tree:
- Use organic mulch. While inorganic mulch is sometimes useful for soil protection, organic materials are best when mulching trees. Shredded bark, leaf compost, and composted wood chips all work well.
- Remember the 3-3-3 Rule. Create a ring of mulch around your tree, 3 inches deep in a 3-foot radius from the trunk, making sure to leave a 3-inch space right around the tree trunk.
- Avoid volcanoes. Don’t pile the mulch against the trunk of your tree. When you’re finished, the mulch should look more like a doughnut than a volcano.
