How to Calculate Mulch
To determine how much mulch you need, measure the length and width of the area you want to cover in feet. Then choose your desired mulch depth — most landscapers recommend 2 to 3 inches for flower beds and 3 to 4 inches for weed suppression around trees. The formula is simple: multiply length × width × depth (in feet), then divide by 27 to convert cubic feet to cubic yards. One cubic yard of mulch covers approximately 108 square feet at 3 inches deep.
How Much Does Mulch Cost?
Bulk mulch typically costs $25–$65 per cubic yard depending on the type. Hardwood mulch is usually $30–$40 per cubic yard, while colored or premium mulch can run $40–$65. Bagged mulch from home improvement stores costs around $3–$6 per 2-cubic-foot bag, which is more expensive per volume but convenient for smaller projects. Delivery fees for bulk mulch usually range from $40–$100 depending on distance.
Types of Mulch
The most common types include hardwood mulch (long-lasting, great for beds), pine bark nuggets (decorative, slow to decompose), cedar mulch (natural insect repellent), dyed mulch (available in red, black, brown), and rubber mulch (permanent, often used in playgrounds). Organic mulches break down over time and improve soil quality, while inorganic options like rubber or stone last longer but don't add nutrients.
