How much mulch do I need for 200 sq ft?

At the recommended 3-inch weed-barrier depth, a 200 sq. ft bed requires 50 cubic feet of mulch, which equals 1.85 cubic yards (or about 2.04 cubic yards with a 10% settling/waste factor). If buying store bags, you will need 25 standard 2.0 cu. ft bags (28 bags with 10% extra).

How many bags of mulch are in a cubic yard?

One cubic yard equals exactly 27 cubic feet. That breaks down to 13.5 standard bags (2.0 cu. ft each) or 18 smaller bags (1.5 cu. ft each). Because stores only sell whole bags, always round up to 14 bags (2.0 cu. ft) per cubic yard.

How many tons of gravel are in a cubic yard?

One cubic yard of standard crushed stone, pea gravel, or driveway rock weighs approximately 1.4 tons (2,800 lbs). Quarries sell loose aggregate by the ton, while bags at home improvement stores weigh 50 lbs and contain 0.5 cubic feet.

How many retaining wall blocks do I need per square foot?

Standard segmental landscape blocks (6 inches high by 12 inches wide) provide 0.5 square feet of face area, meaning you need exactly 2 blocks per square foot. Always add 10% extra for cutting edge blocks and stepped corners.

How do I calculate hedge plant spacing for privacy?

For linear planting, divide total row length by the on-center shrub spacing and add 1. For rapid, dense privacy screening, plant a double-staggered row (two offset parallel rows), which doubles the plant count (Single Row × 2) for immediate complete privacy without sightline gaps.

Should I choose bulk truck delivery or bags from the store?

If your project requires less than 2 cubic yards (up to ~27 bags), bagged materials are convenient and fit in an SUV or pickup bed without a tarp. Once you exceed 3 cubic yards (40+ bags), bulk delivery is typically 30%–45% cheaper even after delivery fees.

Why does QuickYardCalc recommend a 10% waste & settling factor?

Organic mulch and loose topsoil compress by 10–15% after the first heavy rain or watering. Additionally, garden beds rarely have laser-straight edges or perfectly flat subgrades. Adding 10% upfront prevents coming up short on project completion.
