Few landscaping materials pull double duty like cedar mulch. It naturally repels moths, termites, and certain soil-borne pests through volatile oils released as the wood warms, while slowly darkening landscape beds and pathways as it breaks down over roughly two to three growing seasons. The trick is matching chip size and moisture retention to your specific planting zone and bed depth.
I’m Mohammad Maruf — the founder and writer behind Gardening Beyond. I’ve analyzed hundreds of product listings, cross-referenced forestry service data on resin content, and stacked owner feedback across bulk suppliers and bagged brands to isolate which cedar sources hold their aromatic potency longest and which bags deliver the truest volume for the money.
Whether you are topping raised vegetable beds, lining a perennial border, or refreshing the ground cover around specimen shrubs, this guide narrows the field to five reliable choices. You will finish knowing exactly which best cedar mulch option fits your project size and sensory preference without overpaying for heavy bags of dust.
How To Choose The Best Cedar Mulch
Cedar mulch comes in two primary textures: shredded and chips. Shredded fibers mat together slightly, which helps hold steep slopes and resists washing out during heavy rain. Chips or shavings allow faster water infiltration, making them better for flat perennial beds where you want moisture to reach the root zone quickly. Neither is inherently better — your choice depends on whether you need erosion control or percolation.
Particle Size and Bag Volume
Most bags sold online list volume in quarts (qt) rather than cubic feet. A standard 2-cubic-foot bag equals roughly 60 quarts. For a 2-inch-deep bed, 16 quarts covers about 8 square feet. If you are mulching a 4×8-foot raised bed to a 3-inch depth, you need at least 48 quarts — roughly three of the smaller bags or one large bulk pail. Always calculate area before buying, because paying for multiple small bags often costs more per quart than a single larger bag.
Aromatic Longevity and Cedar Species
Eastern Red Cedar (Juniperus Virginiana) contains higher concentrations of the volatile oil thujaplicin, which drives the characteristic cedar scent and pest-repelling effect. Incense Cedar (Calocedrus decurrens) smells pleasantly woody but fades faster. Kiln drying after harvest locks in these oils by driving off free moisture that otherwise allows the aroma to dissipate during storage. If scent longevity matters for a dog run, closet, or perennial border, prioritize kiln-dried Eastern Red Cedar over air-dried or mixed-wood blends.
Chemical Additives and Dyes
“Natural” on the label does not automatically mean dye-free. Some bulk cedar is double-ground and re-dyed to create a uniform chocolate or red color that fades within months. Check the fine print for the words “no added chemicals or dyes” — otherwise you may be spreading colored wood waste rather than pure cedar. The absence of dye matters most in vegetable beds where soil contact is direct.

In‑Depth Reviews
1. Woodlore Kiln Dried Eastern Red Cedar (9 lb)
Woodlore sources Eastern Red Cedar from Missouri and Arkansas, then kiln-dries it in Wisconsin to lock the aromatic oils into the wood. The result is a consistent chip size ranging from about half an inch to an inch, with minimal dust or fines at the bottom of the bag. At 9 pounds, the bag feels dense relative to larger-volume shavings because the chips are solid and not fluffed with air.
This material works best as a perimeter barrier around foundations, under garbage cans, or in vehicle trunks where the strong cedar scent actively repels silverfish, clothes moths, and spiders. The chip format allows water to pass through quickly, so it is less suitable for moisture-loving hosta beds but ideal for dry areas that need long-lasting odor control.
One practical downside: the chips are relatively coarse and do not interlock like shredded mulch, so they can scatter during heavy rain or if you run a leaf blower near the bed. Considering the oil retention and the fact it is responsibly harvested and kiln dried, this is the most potent aroma-per-pound bag in the group.
What works
- Strongest moth-and-pest repellency of any bag tested
- Minimal dust and fines; nearly all usable product
- Responsibly harvested and kiln dried for oil lock-in
What doesn’t
- Coarse chips do not mat together; may scatter in wind
- 9-pound net weight is modest for large landscape beds
2. Double Tree Incense Cedar Wood Chips (16 Quart)
Double Tree packages Incense Cedar shavings in a 16-quart bag that strikes a strong balance between indoor and outdoor use. The shred size is finer than Woodlore’s chips — roughly matchstick dimensions — which lets it nestle around houseplant pots and top-dress small vegetable beds without looking ragged. The texture also works well as pet bedding because the shavings are soft and free of sharp splinters.
The scent profile is noticeably milder than Eastern Red Cedar. Incense Cedar smells clean and woody rather than pungent, which makes it more pleasant for enclosed spaces like a sunroom or covered patio. The moisture retention is respectable for a chip-based mulch; a 2-inch layer held soil moisture for roughly four extra days in potted tomato trials compared to bare soil.
Where this bag loses ground is longevity. The lighter oil content in Incense Cedar means the aroma fades after about two months in direct sunlight. If you need season-long insect repellency, you will need to reapply or top-dress with a rot-resistant species. The 16-quart volume covers roughly 8 square feet at a 2-inch depth, so plan for multiple bags on larger projects.
What works
- Soft, splinter-free texture ideal for pet bedding and litter boxes
- Finer shred blends well with houseplant soil and small raised beds
- Pleasant mild cedar scent that does not overpower indoors
What doesn’t
- Scent fades faster than Eastern Red Cedar in direct sun
- 16 quarts is a modest volume for larger landscape projects
3. MIGHTY109 100% Natural Shredded Cedar (48 Qt Total)
MIGHTY109 bundles five bags that total 48 quarts — effectively 1.6 cubic feet of shredded cedar with no added dyes or chemical accelerants. The shred size is variable, ranging from thin ribbons to quarter-inch chips, which creates a dense interlocking mat once spread. That matting action reduces weed germination by blocking light and slows evaporative water loss better than loose chips.
The 18-pound total weight is manageable even for someone who needs to carry bags from a driveway to a backyard bed. Because the cedar is forest-sourced rather than kiln dried by a specific species name, the oil content is moderate but consistent. The scent is present when first spread but fades to a faint background woodiness within three to four weeks in full sun.
The main trade-off is the packaging. Five separate bags mean more plastic waste and a longer application time if you are opening each one. A small percentage of reviews mention occasional bark chunks from non-cedar trees mixed in, although the bulk of the material is clearly cedar. For the sheer volume per dollar, this is the most economical way to cover a 4×8-foot bed to a 2-inch depth.
What works
- 48 quarts covers a large bed without buying multiple separate products
- Shredded texture mats together for superior weed suppression
- No artificial dyes or chemical additives
What doesn’t
- Five individual bags increase plastic waste and handling time
- Occasional non-cedar bark fragments mixed into the bag
4. Woodchucks Wood Amish Aromatic Cedar Shavings (1 Box)
Woodchucks Wood packs a generous 13-by-13-by-7-inch box full of dry cedar curls and shavings. The texture is fluffy — think coarse sawdust mixed with thin spirals — which creates a lightweight, high-loft layer that works wonderfully inside drawers, linen closets, and beekeeping smokers. The box weighs about 4 pounds but the volume is surprising for that weight because curls trap air.
The source is Amish-harvested, which appeals to buyers who want to support traditional craftsmanship. The shavings are 100 percent natural with no binders or glues, and the cedar species used is aromatic rather than plain white cedar. The scent is strong out of the box and lasts well in enclosed spaces for several months, though exposure to open air accelerates fading.
This product is less effective as a traditional garden mulch because the curls are too light to stay anchored in wind or rain. They also break down faster than shredded or chip forms, needing replenishment after one growing season. Reserve this box for indoor use, small animal bedding, or as a fragrant base layer beneath heavier mulch in a protected planter.
What works
- Voluminous box fills large drawers or pet enclosures with minimal weight
- Amish sourcing appeals to buyers seeking handcrafted goods
- Strong aromatic scent ideal for closets and smokers
What doesn’t
- Light curls blow away easily and do not stay put in open beds
- Decomposes significantly faster than shredded or chip mulches
5. Vundahboah Amish Cedar Wood Mulch Chips (3 Gallon Bag)
Vundahboah sources these chips from Old Order Amish in the foothills of Tennessee and sells them in a compact 3-gallon (12-quart) bag. The chips are uniform, roughly thumbnail-sized, with minimal dust. At 2.4 pounds total weight, this is the lightest bag in the lineup, which points to airy packing rather than dense wood content.
The intended use is clearly accent-scale: a few container planters, a small window box, or a top dressing for a single raised 2×2-foot herb bed. The chips hold their shape well and look tidy when spread, but the volume is too small for any significant landscape bed. The cedar scent is present but mild — noticeable up close but not detectable from across a patio.
The main limitation is economy. If you need only a small decorative touch, the hand-sourced story and consistent chip size justify the premium. For anything beyond a few square feet, you will overpay compared to buying a larger bag from a different brand.
What works
- Uniform chip size looks clean and decorative in small containers
- Hand-sourced from Old Order Amish for a unique provenance story
- Very low dust content; no need to sift before use
What doesn’t
- High cost per quart compared to larger-volume alternatives
- 3-gallon bag insufficient for anything beyond small accents
Hardware & Specs Guide
Eastern Red Cedar vs. Incense Cedar
Eastern Red Cedar (Juniperus Virginiana) contains thujaplicin, a natural fungicide and insect repellent that gives this species its characteristic pungent, spicy scent. Incense Cedar (Calocedrus decurrens) smells sweeter and more balsamic but has roughly half the volatile oil concentration by volume. If your primary goal is pest deterrence for a chicken coop, dog house, or trunk, Eastern Red Cedar offers longer-lasting repellency. If you want a gentle scent for a bedroom planter or covered patio, Incense Cedar is more pleasant at close range.
Kiln Drying and Oil Retention
Kiln drying pulls the internal moisture of the wood down to around 6 to 8 percent. Dry wood releases aromatic volatile organic compounds (VOCs) more slowly because the oil is trapped within the cell walls rather than flushed out by evaporation. Bags labeled “kiln dried” and “aromatic” retain noticeable scent for 6 to 12 months in open air, whereas air-dried cedar typically loses its smell within 8 to 12 weeks. Check the manufacturer description for the specific phrase “kiln dried” — not just “natural” or “100% cedar.”
