Wood Chips

Bulk wood chips typically come from tree trimming and removal operations, where branches and trunk sections are run through a chipper that produces the characteristic mixed particle sizes, from small fragments to pieces a few inches across. Because the source material includes bark, twigs, and sometimes leaves, the resulting product has more textural variety than screened hardwood bark mulch, which is processed for uniform particle size. Arborist chip loads, whether sourced fresh from tree work or from a bulk yard, can vary from load to load in species mix and moisture content, which is why weight per cubic yard swings from about 400 lbs dry to 1,000 lbs wet. Buyers who want a consistent, weed and invasive seed free product should specifically ask for clean chips, since unscreened arborist loads can carry seed or plant fragments from species like ivy or holly that sprout unexpectedly in a bed. Graded landscape wood chips sold in bulk are generally more consistent than a random arborist drop off load, though both are legitimate options depending on budget and how much variability a project can tolerate.

Start by clearing the area of turf and debris, then lay landscape fabric only where a permanent path base is intended, not under general bed mulch, since fabric under standard bed applications interferes with the fungal decomposition process that builds soil health over time. For beds and tree rings, spread chips directly over bare soil at 2 to 3 inches, tapering off near stems and trunks. For paths and play areas, a slightly deeper 3 to 4 inch layer over a compacted base or landscape fabric gives a firmer, longer lasting surface, since chips do not knit together the way shredded mulch fibers do and instead rely on depth and coarse interlock for stability. Avoid exceeding 4 inches anywhere, since layers beyond that become water repellent and can starve roots of rainfall. Plan on a light annual top dress rather than full replacement, since coarse chips break down more slowly than shredded material and can hold their structure for several seasons before needing a full refresh.

Compared with shredded hardwood mulch. Shredded mulch is finer and more uniform, knitting together into a mat that resists wind and washing on flat ground. Wood chips are chunkier, do not mat the same way, and hold up better as a stable path or play surface over time, though on slopes shredded material generally stays in place more reliably than loose chips.

Compared with pine straw. Pine straw interlocks and resists washing away on slopes, breaking down faster and needing more frequent replacement. Wood chips retain moisture and suppress weeds effectively on flat beds and paths but are more prone to migrating downhill than pine straw during heavy rain.

How much wood chip mulch do I need to order. At a standard 3 inch depth, one cubic yard covers roughly 100 to 108 square feet, so divide your total bed or path square footage by 100 to get a workable cubic yard estimate. For a thinner 2 inch application, one yard stretches to about 162 square feet. Always round up slightly since settling and uneven ground reduce effective coverage.

How wood chips are sold and delivered in bulk. Wood chips are sold by the cubic yard for bulk delivery rather than by the bag, which is far more economical for beds, paths, or play areas of any real size. Loads are dumped at a driveway or accessible spot on the property, and because weight per yard varies with moisture content, cubic yard volume, not tonnage, is the more reliable way to plan and order the right amount.
