Mulch Weight Per Yard, Dry and After Rain
How much does a yard of mulch weigh? Between 300 and 700 lb dry, depending on the wood. Shredded hardwood sits at the heavy end near 600 lb, cypress at the light end near 400. Rain changes all of it: the same yard can gain half its weight again in a night.
Why mulch weight swings so much
Mulch is mostly air. Shredded wood stacks in a tangle with gaps everywhere, and the gaps are a large share of any cubic yard you buy. That is why a volume of it weighs so little compared to soil or stone.
Which is also why water changes everything. Those gaps fill, and the wood itself drinks. A yard that came off the pile at 600 lb in August can weigh 900 lb after a wet week, with not one extra shred of mulch in it.
So any single number for mulch weight is a snapshot of a condition rather than a property of the material. That is the thing worth carrying away from this page, and it is why every row below has two columns.
How much a cubic yard of mulch weighs
300 to 700 lb dry for wood. Rubber is the exception at about 1,150 lb, roughly double the heaviest wood, because ground tire has none of the air that makes bark light.
| Mulch | Dry | Dry range | After rain | Gain |
|---|---|---|---|---|
| Shredded hardwood | 600 lb | 500 to 700 | 900 lb | +50% |
| Dyed black or brown | 600 lb | 500 to 700 | 900 lb | +50% |
| Cedar | 550 lb | 500 to 600 | 825 lb | +50% |
| Cypress | 400 lb | 300 to 500 | 600 lb | +50% |
| Pine bark nuggets | 450 lb | 400 to 500 | 630 lb | +40% |
| Rubber mulch | 1,150 lb | 800 to 1,200 | 1,150 lb | none |
Read the last column and the point of the page is there. Wood gains between a half and two thirds of its own weight in rain. Rubber gains nothing, because there is nowhere in a rubber crumb for water to go.
For comparison, a cubic yard of topsoil is around 2,200 lb and gravel closer to 2,800. Mulch is by a distance the lightest thing on this site, which is why it is the one bulk material most people do move themselves.
Weight by mulch type
The spread between the lightest and heaviest wood is about 50%. That is enough to matter on a full load and not enough to choose a mulch over.
Dyed black or brown is the heaviest of the woods because it is dense and finely shredded, so it packs with fewer voids. Cypress sits at the other end, being lighter timber and cut coarser.
Pine bark nuggets behave differently again. They are chunky and waxy, so they shed water rather than soaking it up, and they gain the least of any wood when it rains. If you are hauling in a wet season, that is a genuine advantage.
Colour makes no difference. Dyed mulch is the same wood with pigment on it, and the dye adds nothing you could weigh. If a dyed load feels heavier, it was wetter.
Wet vs dry weight
Assume about 50% on shredded wood after heavy rain. Plan the load around that figure, not the dry one.
The reason it matters is that mulch is usually bought in the wet half of the year. Spring deliveries come off piles rained on for weeks. So the dry figure in any chart, including this one, is the optimistic case.
You cannot tell by looking. Drained mulch looks the same as soaked mulch, and the difference sits in the middle of the pile rather than the surface. Squeeze a handful. If it clumps and stays clumped, plan for the wet column.
It dries out fast once spread. A bed mulched in the rain carries a lot of extra weight on the day and almost none a week later. That matters for the truck and not at all for the plants.
How much a bag of mulch weighs
A 2 cu ft bag, which is the standard, runs 30 to 44 lb dry. Hardwood is about 44 lb.
Bagged mulch tends to run a little lighter than the same volume in bulk, because it is bagged under cover and sealed. A bag that has spent a wet fortnight outside a store is a different matter and can reach 45 lb.
| Mulch | 1.5 cu ft | 2 cu ft | 3 cu ft | Bags per yard (2 cu ft) |
|---|---|---|---|---|
| Shredded hardwood | 33.3 lb | 44.4 lb | 66.7 lb | 14 |
| Dyed black or brown | 33.3 lb | 44.4 lb | 66.7 lb | 14 |
| Cedar | 30.6 lb | 40.7 lb | 61.1 lb | 14 |
| Cypress | 22.2 lb | 29.6 lb | 44.4 lb | 14 |
| Pine bark nuggets | 25 lb | 33.3 lb | 50 lb | 14 |
| Rubber mulch | 63.9 lb | 85.2 lb | 127.8 lb | 14 |
The last column is the one that surprises people. It takes 14 standard bags to make a single cubic yard, so a job needing three yards is over forty bags of lifting.
2 cu ft and 3 cu ft bag weights
Two cubic feet is the size almost every retailer stocks. Three cubic feet turns up at builders merchants and on contractor pallets, and it is half again as heavy per bag.
In hardwood that is 44.4 lb against 66.7 lb. Neither is difficult on its own. Forty of them across a driveway is another matter. So check which size you are being quoted before comparing two prices per bag.
A full pallet of 65 standard bags comes to about 2,889 lb in hardwood. Pallets run 60 to 75 bags, so expect somewhere between 1,300 and 2,000 lb. And expect a truck with a forklift, not a pickup.
Will it fit in your truck?
One yard of dry wood mulch, yes, easily. Two is fine in most half-tons. Three is over the line for nearly all of them once you allow for the mulch being damp.
| Load | Hardwood dry | Hardwood wet | Verdict |
|---|---|---|---|
| 1 yd³ | 600 lb | 900 lb | Fine either way |
| 2 yd³ | 1,200 lb | 1,800 lb | Over a half-ton payload |
| 3 yd³ | 1,800 lb | 2,700 lb | Over a half-ton payload |
Most half-ton pickups carry near 1,000 to 1,500 lb. The sticker in the door jamb is the figure that counts, not the badge on the tailgate. And payload includes you, your passengers and anything already in the bed.
Volume runs out before weight does with mulch, which is unusual. A short bed holds about two cubic yards heaped, so on dry wood you will fill the truck before you trouble the axle. On rubber the opposite is true, and one yard is plenty.
Convert your own volume
The tool below takes cubic yards or a bag count. It returns the weight for the type and condition you pick, plus what that means for a pickup.
Your result
- In bags
- 3 cubic yards is 41 2 cu ft bags at 44.4 lb each. A full pallet of 65 would weigh about 2,889 lb.
- What your truck can take
- At 1,800 lb this is over what a half-ton pickup is rated to carry, so it wants two trips or a delivery.
- How this is worked out
- 3 yd³ × 600 lb = 1,800 lb
It runs off the same weight table printed above, so the tool and the chart can never disagree with each other. Switch the condition to wet and watch the pickup verdict change, because that is the swing that catches people out on delivery day.
Mulch weight questions
How much does a yard of mulch weigh?
Between 300 and 700 lb dry, depending on the wood. Shredded hardwood is the heavy end at about 600 lb a cubic yard, cypress the light end near 400. After a couple of days of rain the same yard can gain half its weight again.
How much does a bag of mulch weigh?
A standard 2 cu ft bag runs 30 to 44 lb dry. Hardwood is around 44 lb. Bags that have sat outside on a pallet in the rain come in heavier, sometimes closer to 45 lb.
How much does a cubic yard of mulch weigh?
The same as a yard of mulch, since they are the same unit. Wood runs 300 to 700 lb dry. Rubber mulch is the outlier at roughly 1,150 lb, which is about double the heaviest wood.
How much does 2 cubic feet of mulch weigh?
About 44 lb for hardwood, 30 lb for cypress. Two cubic feet is the standard bag size, and it is a fraction of a yard: it takes 14 bags to make one cubic yard.
How much does a pallet of mulch weigh?
Around 2,889 lb for 65 hardwood bags at 2 cu ft. Pallets run 60 to 75 bags depending on the supplier, so the total lands somewhere between 1,300 and 2,000 lb. That is a forklift delivery, not a pickup.
Does wet mulch weigh more?
A great deal more. Wood absorbs water, so a yard of shredded hardwood at 600 lb dry can reach 900 lb after heavy rain. That gain is what turns a legal pickup load into an overloaded one, and it happens overnight.
Will a yard of mulch fit in a pickup truck?
A yard of dry wood mulch will, comfortably. At 600 lb it sits well inside a half-ton pickup's payload. Two yards is borderline and three is over the limit for most half-tons, especially if the mulch is wet.
Why is rubber mulch so much heavier?
Because it is ground tire rather than wood. Rubber is denser to begin with, and it does not have the air pockets that make bark light. At roughly 1,150 lb a cubic yard it is close to double the heaviest wood mulch.
