How Much Mulch Do You Need?

- Multiply the length by the width. This gives you the area in square feet.
For example:

Deciding the Depth of Mulch
After finding the area, decide how deep to spread the mulch. A common depth is 2 to 4 inches. Here’s how to choose:
- 2 inches is good for flower beds.
- 3 inches is great for vegetable gardens.
- 4 inches works well for trees and shrubs.
For most raised beds, 3 inches is a good choice. It helps keep moisture in without smothering the plants.
Calculating the Amount of Mulch Needed
Now, let’s calculate how much mulch you need. Use this formula:
Area (sq ft) × Depth (inches) ÷ 12 = Cubic Yards of Mulch
Remember, there are 12 inches in a foot. So, you divide by 12 to convert inches to feet.
Let’s use our previous example:
Now, plug in the numbers:
12 × 3 ÷ 12 = 3 cubic feet of mulch.
Now we need to convert cubic feet to cubic yards. There are 27 cubic feet in a cubic yard. So:
3 ÷ 27 ≈ 0.11 cubic yards.
You would need about 0.11 cubic yards of mulch for this raised bed.
Where to Buy Mulch
You can buy mulch in many places. Here are some options:
- Garden centers
- Home improvement stores
- Landscaping companies
- Online retailers
Check for local options. Some places sell mulch in bulk. This can be cheaper than bagged mulch.

- First, clear the area of weeds and debris.
- Next, place the mulch evenly over the soil.
- Use a rake to spread it out.

By following these steps, you will have a nice layer of mulch.
