Is it ok to use mulch on a Meyer Lemon tree?

Question

This tree is planted outside and it gets morning sun and afternoon shade.

Answer 1

There should be no reason not to mulch.

Mulching will help with moisture retention. Do keep the mulch away from the trunk of the tree to avoid causing fungus problems. A 6 inch area around the base of the trunk should be fine.
