Ensure that drainage around area to be mulched is proper and that you will not create a drainage issue once the mulch is in place.
For flower gardens, apply mulch in a 2-4 inch layer to create a nice uniform blanket over the bed in order to maximize the benefit of the mulch.
For trees, it is preferable to mulch area as wide as the tree drip. Place mulch in a 2-4 inch layer and keep away from the tree trunk or stems so the trunk is fully exposed.
