1. What is Mulch Coverage Calculation?

The mulch coverage calculation converts cubic feet of mulch to square feet of coverage based on desired depth. This helps determine how much area a given volume of mulch will cover at your preferred thickness.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( Volume \) — Amount of mulch in cubic feet
• \( Depth \) — Desired mulch depth in inches
• 12 — Conversion factor (inches to feet)

Explanation: The formula converts depth from inches to feet (dividing by 12) then divides volume by this depth to get coverage area.

3. Importance of Proper Mulch Depth

Details: Proper mulch depth (typically 2-4 inches) is crucial for weed suppression, moisture retention, and plant health. Too thin won't be effective, too thick can harm plants.

4. Using the Calculator

Tips: Enter volume in cubic feet (standard bag size is 2 cu ft) and desired depth in inches (recommended 2-4 inches). All values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: How much mulch do I need for a 100 sq ft area?
A: At 3 inch depth: 100 × (3/12) = 25 cubic feet (about 12-13 standard 2 cu ft bags).

Q2: What's the recommended mulch depth?
A: 2-4 inches for most applications. 2 inches for fine mulch, 3-4 inches for coarse mulch.

Q3: How many square feet does a 2 cu ft bag cover?
A: At 3 inch depth: 2 ÷ (3/12) = 8 square feet per bag.

Q4: Should I account for mulch settling?
A: Yes, mulch compacts over time. Add 10-15% more if calculating for long-term coverage.

Q5: How often should mulch be replaced?
A: Typically annually, as organic mulch decomposes. Top up as needed to maintain depth.
