I do fertilize and water regularly, but I know that I should be mulching them and I’m not quite sure how. At the moment I have lots of leaves around the base of the trees because I didn’t clean up after winter yet. Is it a good idea to leave the leaves there? I feel that there are too many leaves there not allowing the cedars to breathe. I’m not sure if I’m correct on that.

Or should I remove the leaves, add some topsoil and then wood chips for mulch? Any suggestions? I could add some pictures later.
