Also, what is the best mulch for perennials?
A. For vegetable gardens, an inch of dried grass clippings, straw, chopped corncobs, or shredded newspaper works great. Annuals and perennials grow best with a couple of inches of wood chips on the ground, and trees and shrubs would be well suited with a 2- to 3-inch-deep layer of mulch.
Also Know, do you have to remove old mulch before applying new mulch? For an annual bed, remove old mulch before you till the soil and add compost.

Remove as much of the old layers as possible before you add more.
