The most popular mulches are organic mulches like bark and hardwood mulch. There are many types and variations of both including the color, shred and trees. In general, bark mulch typically lasts longer than hardwood and decomposes over time, adding nurturance to your soil. Hardwood is probably the most commonly used because of its ability to be shredded to various textures and ease of colorization. Hardwood decomposes quickly and provides nurturance to your plants and soil. Inorganic mulch such as lava rock and pee gravel do not decompose and are more of a permanent solution for soil erosion and landscape design. Inorganic mulches are most commonly used in desert type climates.

What is the difference between organic and inorganic mulch?
Organic mulch can be made of many substances which are naturally occurring. Hardwood mulch and Hardwood Bark Mulch are two of the most common. However, pine needles, leaves, or even grass clippings are sometimes used as mulch. Organic mulches decompose over time. Organic mulch can attract insects, mostly slugs and worms witch is great for your soil. Unfortunately sometimes termites and other annoying pests get into it as well. Usually organic mulch should be replaced every couple of years.

How do I determine how much mulch I need?
To calculate the volume of mulch you’ll need, multiply the square footage of the area to be covered (SF) by the depth of the mulch (DM). Multiply the result by 0.0031 to determine the number of cubic yards you’ll need. The equation looks like this:
SF x DM x 0.0031 = Cubic Yards.
What thickness in depth should I lay mulch?
To maintain moisture and effectively prevent weed growth, the recommended depth is 3 inches thick.
How many square feet of mulch are in a cubic yard?
One cubic yard will cover a 324 square-foot area with one inch depth.
How many bags of mulch do I need to cover 1 yard?
Bagged mulch usually comes in 2 cubic foot and 3 cubic foot sizes.
2 cubic foot bags = 14
3 cubic foot bags = 9
What is the difference between bagged and bulk mulch?
It’s a matter of preference and price. Some people prefer to have a load of mulch delivered to their house and use a wheelbarrow to move it throughout the yard. Some prefer to carry bags to each landscape bed.
Bulk mulch is generally much cheaper than bag mulch. However, if you need less than 2 yards of mulch you may want to consider using bags. Some landscape supply companies have a minimum delivery of 2-3 cubic yards.
