What West Coast Chip Harvesters supplies

Bulk mulch comes in hardwood, dyed, cedar, cypress and pine bark varieties. Bought loose by the yard it usually costs well under half the per-volume price of bagged mulch at a big-box store, which is why most repeat buyers switch to bulk.

Double-ground hardwood is the common default and knits together well on slopes. Dyed mulch holds colour longer but fades unevenly. Pine bark is lighter and floats, so it travels in heavy rain. Ask how long the pile has been sitting — fresh, hot mulch can burn tender plants.

Screened topsoil is the workhorse material for new lawns, raised beds and regrading work. Yards typically screen to ½" or ⅜" to pull out rocks, roots and clods, and many sell blended mixes that cut native soil with compost or sand to improve structure and drainage.

How much material you need

Mulch is sold by the cubic yard. A cubic yard of mulch weighs roughly 400–800 lbs, so a pickup can typically manage two to three yards.

As a rough guide: 1 yard covers about 100 sq ft at 3 in; 3 yards covers about 325 sq ft at 3 in; 10 yards covers about 1,080 sq ft at 3 in.

Have length, width and target depth ready when you phone. Yard staff convert those into cubic yards far more reliably than a generic online calculator, and they know how their own material settles.

Ordering and delivery

Ask about delivery minimums and trip charges up front — for smaller orders these often matter more to the final bill than the headline per-cubic yard price.

Check where the truck can actually dump. Tandem trucks need overhead clearance and firm ground, and most drivers will not reverse across a soft lawn or a new driveway. If access is tight, ask whether they run a smaller truck or can leave the load at the kerb.

Best time to buy in California

California's longer growing season spreads demand across more of the year, which generally means better availability than northern markets. Even so, spring remains the peak for mulch, and summer heat makes midday loading and installation punishing — early-morning pickups are worth the alarm clock. Autumn and winter are frequently the best value windows, with shorter queues and more flexible delivery scheduling.
