  • Check for spring/fall sales

🌿 Understanding Mulch Measurements

When shopping for mulch, you'll encounter two main buying options: bagged mulch (sold in cubic feet) and bulk mulch (sold by the cubic yard). Understanding the conversion between these units helps you buy the right amount and get the best value.

Key Conversion: 1 Cubic Yard = 27 Cubic Feet

  • 2 cu ft bags: 13.5 bags = 1 cubic yard (most common size)
  • 3 cu ft bags: 9 bags = 1 cubic yard
  • 1.5 cu ft bags: 18 bags = 1 cubic yard

How Deep Should Mulch Be?

2 Inches — Light Coverage

Good for decorative purposes and light weed suppression. Best for refreshing existing mulch beds. 1 cubic yard covers 162 sq ft at this depth.

3 Inches — Standard (Recommended)

Ideal balance of weed control, moisture retention, and soil temperature regulation. 1 cubic yard covers 108 sq ft at this depth.

4 Inches — Heavy Coverage

Maximum weed protection. Be careful not to pile against plant stems or tree trunks. 1 cubic yard covers 81 sq ft at this depth.

🌿 Quick Facts

1 yard = 13.5 bags (2 cu ft)

Standard depth: 2-3 inches

Bulk saves 30-50% vs bags

⚠️ Common Mistakes

  • Piling mulch against tree trunks (causes rot)
  • Going too thin (<2") — weeds will grow through
  • Not buying 10% extra for settling
  • Forgetting delivery fees for bulk

Frequently Asked Questions

One cubic yard equals 27 cubic feet. For the most common 2 cubic foot bags, you need 13.5 bags per yard (27 ÷ 2 = 13.5). For 3 cubic foot bags, you need 9 bags per yard. For smaller 1.5 cubic foot bags, you need 18 bags per yard.

You need approximately 13-14 bags of standard 2 cubic foot mulch to equal 1 cubic yard. If using larger 3 cubic foot bags, you only need 9 bags. Always round up and buy 10% extra to account for settling and spillage.

Bulk mulch is typically 30-50% cheaper than bagged mulch. For example, bagged mulch might cost $3-5 per 2 cu ft bag ($40-67 per cubic yard), while bulk mulch costs $30-45 per cubic yard. For projects requiring 2+ cubic yards, bulk is significantly more economical.

A standard 2 cubic foot bag covers about 12 square feet at 2 inches deep, or 8 square feet at 3 inches deep. A 3 cubic foot bag covers about 18 square feet at 2 inches deep, or 12 square feet at 3 inches deep.

For 500 square feet at 2 inches deep, you need about 42 bags (2 cu ft) or 28 bags (3 cu ft). At 3 inches deep, you need about 63 bags (2 cu ft) or 42 bags (3 cu ft). This equals approximately 3-4.6 cubic yards depending on depth.

You need 18 bags of 1.5 cubic foot mulch to equal one cubic yard (27 ÷ 1.5 = 18). These smaller bags are easier to carry but require more bags overall, so they're best for small projects or when heavy lifting is a concern.

🌿 Disclaimer: Calculations include a 10% buffer for settling and spillage. Actual coverage may vary based on mulch type, moisture content, and spreading technique. Bulk prices may not include delivery fees.
