Tip: How much “landscape” mulch do I need?

3″ is the recommended depth for areas that have a base of bark down. If it is the first time you are putting bark down or it has been so long that you can see the roots of your trees and mostly bare dirt, then 4″ is ideal to re-establish a base due to the uneven ground that is exposed.
