Dyed Black Mulch
Dyed black colored mulch is sold by the yard and picked up at the store. Mulch actually prevents water loss from around plants, breaks down to add nutrients to the soil, and helps to prevent weed germination when used in the recommended thickness. Colored mulch will give your landscaping project eye catching curb appeal.
A cubic yard is 3 feet wide by 3 feet high by 3 feet deep. Determine the size of the area you want to cover in square feet. To do this, multiply the length by the width of the space. Next decide how deep you will want your mulch in inches. Multiply the square feet of your garden space by the inches of mulch depth, divide that number by 324. This is the number of cubic yards of mulch you will need.
