Bulk mulch is sold by installed cubic yard. It arrives fluffed and settles after watering; that is a measurement basis, not a reason to automatically order more.

Estimator confidence
HighBulk mulch is sold by installed cubic yard. It arrives fluffed and settles after watering; that is a measurement basis, not a reason to automatically order more.
Improve confidence: Plan a seasonal top-off rather than over-ordering the initial delivery.
Why this behavior applies: Ordering the geometric installed volume is the honest baseline; decomposition is a separate long-term line.
- Target depth after settling — Fresh mulch compresses to roughly 80–90% of installed depth in the first month.
- Bed geometry — Long, narrow beds waste more mulch at edges than a square bed of the same area.
- Mulch blend — Fine bark compresses more than coarse chips.
- For mature beds, 2 inches is usually enough — deeper smothers shallow-rooted perennials.
- Refresh with 1 inch annually rather than piling on 3+ inches at once.
- Bagged mulch is fine under 1 cubic yard; anything larger is much cheaper in bulk.
- Piling mulch against tree trunks ("mulch volcanoes") — invites rot and pests.
- Ignoring irregular bed shapes when estimating waste.
- Using dyed mulch near vegetable beds without confirming the dye is plant-safe.
Smart tips
- Ordering 5–10% extra is standard on irregular layouts. Running short costs more than the excess.
How it's calculated
Area is derived from your shape inputs and converted to sq ft.
Depth is converted to feet; cubic feet = area × depth.
Cubic yards = cubic feet ÷ 27, then × (1 + waste %) × (1 + compaction %).
Estimated tons = cubic yards (with waste) × 0.35.
Truckloads = cubic yards (with waste) ÷ truck capacity.
Total cost = cubic yards (with waste) × price per cubic yard + delivery.
Material assumptions
- Mulch density: 0.35 tons per cubic yard.
- Recommended depth: 2–4 inches for weed control.
- One cubic yard covers ~108 sq ft at 3 inches deep.
- One 2 cu ft bag = 0.074 cubic yards.
