If you’ve ever overbought mulch—or had to make multiple trips for more—you’re not alone. Calculating how much mulch your Cabot garden or landscape needs can be confusing, but a few simple formulas make it easy.
Whether you’re mulching flower beds, trees, walkways, or commercial properties, knowing how to accurately measure and order your mulch saves time, labor, and money.
In this post, we’ll walk through step-by-step instructions on how to calculate mulch volume, understand depth and coverage, and choose the right mulch type for your landscape.
Why Proper Mulch Calculation Matters
Getting the right amount of mulch has more benefits than you might think:
Saves Money: Avoid paying for excess material or extra deliveries.
Ensures Even Coverage: Promotes consistent moisture retention and weed suppression.
Improves Plant Health: Prevents over-mulching, which can cause root suffocation.
Enhances Curb Appeal: Keeps Cabot gardens and lawns looking professional and well-maintained.
Step 1: Measure Your Garden or Mulch Area
Start by determining the square footage of the area you plan to mulch.
For a rectangular or square area:
Length (ft)×Width (ft)=Area (sq. ft.)\text{Length (ft)} × \text{Width (ft)} = \text{Area (sq. ft.)}Length (ft)×Width (ft)=Area (sq. ft.)
For circular areas (like around trees):
3.14×(Radius)2=Area (sq. ft.)3.14 × (\text{Radius})^2 = \text{Area (sq. ft.)}3.14×(Radius)2=Area (sq. ft.)
💡 Example: If your flower bed is 10 feet by 15 feet:
10 × 15 = 150 square feet.
Step 2: Choose Your Mulch Depth
Depth matters depending on your landscaping goals:
PurposeRecommended DepthFlower Beds2–3 inchesTrees3–4 inchesSlopes / Erosion Control4–5 inchesWalkways / Play Areas2–3 inches
Too little mulch won’t suppress weeds effectively; too much can trap moisture and harm plant roots.
Step 3: Convert to Cubic Yards
The formula for cubic yards is:
Area (sq. ft.) × Depth (in inches)324=Cubic Yards\frac{\text{Area (sq. ft.) × Depth (in inches)}}{324} = \text{Cubic Yards}324Area (sq. ft.) × Depth (in inches)=Cubic Yards
💡 Why 324?
One cubic yard covers 324 square feet at 1 inch deep (27 cubic feet × 12 inches = 324 cubic inches per square foot).
Example Calculation
Let’s say your flower bed is 150 sq. ft., and you want 3 inches of mulch:
150×3324=1.39 cubic yards\frac{150 × 3}{324} = 1.39 \text{ cubic yards}324150×3=1.39 cubic yards
Round up to 1.5 cubic yards to ensure full coverage.
Step 4: Converting to Bags
If you’re buying bagged mulch (2 cubic feet per bag):
Cubic Yards×13.5=Bags Needed\text{Cubic Yards} × 13.5 = \text{Bags Needed}Cubic Yards×13.5=Bags Needed
So for our 1.5 cubic yards:
1.5 × 13.5 = 20.25 bags → Buy 21 bags.
Step 5: Consider Mulch Type and Material
Different mulch types spread and settle differently.

Cabot Landscaping offers professional mulch delivery with color options like redwood, cedar, and dark bark mulch to suit your garden’s style and soil health needs.
Step 6: Account for Settling
Mulch compacts about 10–20% after installation.
Add a small buffer to your order—5–10% more mulch—especially for larger landscapes.
Example: If your total is 1.5 cubic yards, order 1.65 cubic yards to compensate.
Step 7: Tools for Easy Calculation
Several online mulch calculators can help verify your math, but knowing how to do it manually ensures accuracy when discussing orders with Cabot Landscaping professionals or requesting mulch delivery quotes.
Step 8: When to Reapply Mulch
In Cabot, Arkansas, harsh sun and heavy rain gradually break mulch down.
Plan to refresh mulch:
Every 12–18 months for organic bark mulch.
Every spring for colored or dyed mulches.
Immediately after major storms or erosion.
Routine maintenance keeps your landscape healthy, your soil rich in nutrients, and your property looking fresh.
