If you wish, you can place a plastic sleeve around the trunk of a young tree to prevent damage from lawnmowers, edge trimmers, etc. It is not absolutely necessary to do so, however, since mulch already does the job. If you do decide to protect your tree or shrub, make sure that the sleeve isn’t touching the trunk. If it does, it will keep the bark moist and make it more susceptible to injury, insect pests and canker and fungal infections.
