When planning a landscaping project in Gaithersburg, MD, one of the most common questions homeowners face is whether to buy mulch in bulk by the cubic yard or in individual bags. Both options have their pros and cons, and knowing the right quantity to purchase can make all the difference in your project’s success. This guide will explain the differences between cubic yard and bagged mulch, help you calculate how much you need, and guide you toward making the best decision for your property.

What Is Mulch and Why Is It Important?

Mulch is any material spread over the surface of the soil to retain moisture, suppress weeds, regulate soil temperature, and enhance the landscape’s appearance. Common types include shredded hardwood, bark, pine straw, and dyed wood chips.

Benefits of Mulch:

• Reduces weed growth

• Retains soil moisture

• Regulates soil temperature

• Enhances curb appeal

• Prevents soil erosion

What Is a Cubic Yard of Mulch?

A cubic yard is a unit of volume equal to 27 cubic feet (3 feet long x 3 feet wide x 3 feet deep). When you purchase mulch in bulk, it is often sold by the cubic yard and delivered in a truck or trailer. Bulk mulch is ideal for large projects or when you want a consistent look throughout your yard.

1 Cubic Yard = 27 Cubic Feet = Approximately 13.5 Bags (2 cu. ft. each)

What Is Bagged Mulch?

Bagged mulch is pre-packaged in convenient sizes, typically 1.5 or 2 cubic feet per bag. It is available at local garden centers, hardware stores, or home improvement stores.

Typical Bag Sizes:

• 1.5 cu. ft.

• 2.0 cu. ft.

• Sometimes 3.0 cu. ft.

Bagged mulch is easier to transport and store, making it a great choice for smaller landscaping jobs.

How to Calculate How Much Mulch You Need

To determine how much mulch you need, you’ll first need to calculate the area to be covered and the desired depth.

Formula:

Square footage x desired depth (inches) ÷ 324 = cubic yards needed

Example: You want to cover 500 square feet with 3 inches of mulch.

500 x 3 ÷ 324 = 4.63 cubic yards

You would round up and order 5 cubic yards of mulch.

Bag Calculation: If you need 4.63 cubic yards:

4.63 x 13.5 (bags per cubic yard) ≈ 62.5 bags (2 cu. ft. each)

Pros and Cons of Cubic Yard Mulch

Pros:

• More economical for large projects

• Fewer plastic bags = more environmentally friendly
