How many bags do I need?

Use the mulch calculator. Enter your bed dimensions and desired depth and it gives you a bag count based on your bag size. A 10x10 bed at 3 inches deep takes about 13 standard 2 cubic foot bags.

Should I use landscape fabric under mulch?

For most garden beds, no. Landscape fabric blocks water and air exchange, breaks down over time into a tangled mess, and doesn't stop weed seeds that blow in on top of the mulch. Two to three inches of mulch suppresses weeds more effectively in the long run. Fabric is useful under gravel paths and hardscape, not in planting beds.

Bulk or bagged mulch?

Buy bulk when you need 3 or more cubic yards — it's 30 to 50% cheaper and means less plastic waste. Buy bagged when you need less than 3 yards, don't have a truck, or need specific types your local bulk supplier doesn't carry. Most landscape supply companies deliver starting at 3 to 5 yards minimum.

What does triple-shredded mean?

Triple-shredded mulch has been processed through a shredder three times, producing finer, more uniform pieces. It interlocks better than coarse chips, stays in place more reliably, and has more surface area — which means it breaks down faster and adds organic matter to the soil sooner.

Best Mulch for Gardens

The right mulch depends on what you're mulching. Ornamental beds, vegetable gardens, tree rings, and slopes all have different requirements.

Choosing by application

Ornamental flower and shrub bedsShredded hardwood or dyed wood mulch

Looks clean, stays in place, breaks down into organic matter

Vegetable gardensStraw or shredded leaves

Breaks down fast and adds nitrogen; wood chips tie up nitrogen as they decompose

Tree ringsShredded hardwood at 3 inches

Keeps a mulch-free zone right at the trunk — never pile mulch against bark

Slopes and drainage areasPine bark nuggets

Heavier and stays in place; shredded mulch washes out on steep grades

Acid-loving plantsPine bark or pine straw

Lowers soil pH over time — good for blueberries, azaleas, hollies

Bagged vs. bulk

At 3 or more cubic yards, bulk mulch from a landscape supplier costs roughly half what bagged mulch costs per cubic yard, and you eliminate dozens of plastic bags. Under 3 yards, bagged is more practical — you can mix types, store unused bags, and avoid a minimum delivery charge. The mulch calculator shows you your cubic yard total so you can make the call.

What to avoid

Fresh wood chips from a tree service are fine for pathways and around trees but aren't ideal in planting beds — they tie up nitrogen as they decompose, which competes with your plants during the first season. Rubber mulch lasts forever but heats up significantly in direct sun and leaches zinc into the soil. Hay looks like straw but contains seeds that will sprout in your beds.
