How much does 1 yard of mulch weigh? A yard of mulch usually weighs between 400 and 800 pounds. This is a cubic yard mulch weight. The exact weight changes a lot. It depends on the kind of mulch you choose. It also depends a lot on how much water is in it. This means the average weight of a yard of mulch is just an estimate. So, how many pounds is a yard of mulch? Think of it as a big range, typically from 400 lbs when very dry to 800 lbs or more when soaking wet. Knowing this helps you plan.

Why Mulch Weight Matters
Knowing how much mulch weighs is important for a few reasons.
It helps you figure out how to get it home. Can your truck carry it? Do you need it delivered?
It helps you know the bulk mulch weight you are ordering. This is key for large projects.
It tells you how much work it will be to move it. A few hundred pounds is heavy!
It can even affect the cost. Sometimes, delivery fees depend on weight or how many loads are needed.
What Is a Cubic Yard of Mulch?
Before we talk more about weight, let’s picture a cubic yard. It is the standard way mulch is sold in bulk.
A cubic yard is a measure of volume, not weight.
Imagine a box that is 3 feet wide.
Now imagine it is also 3 feet long.
And it is 3 feet tall.
That box is one cubic yard.
Think of it like this: 3 feet x 3 feet x 3 feet = 27 cubic feet.
So, one cubic yard is equal to 27 cubic feet.
Factors Affecting Mulch Weight
The weight of mulch can change a lot. Several things cause these changes.
Type of Mulch
The biggest factor is the material the mulch is made from. Different materials have different densities. Density is how much “stuff” is packed into a space.
- Wood Chip Mulch Weight: Wood chips come from grinding up trees or wood waste. The weight depends on the type of wood and the chip size. Hardwoods are usually heavier than softwoods. Larger, chunkier chips might have more air space. Wood chip mulch often weighs around 400-600 pounds per cubic yard when dry.
- Shredded Bark Mulch Weight: This mulch comes from the bark of trees. It’s often stringy or fibrous. Different barks (like pine, cypress, or hardwood) have different weights. Shredded bark mulch tends to hold water more easily than chunky chips. Its weight is often similar to wood chips, maybe 400-700 pounds dry.
- Pine Mulch Weight: This can mean pine bark or pine needles. Pine bark mulch is a type of shredded or chipped bark. Pine needles are much lighter. A cubic yard of loose pine needles might only weigh 200-300 pounds dry. Pine bark weight is more like other bark mulches.
- Other Mulch Types:
- Compost or Soil Blends: These are often heavier than pure wood mulches. They can weigh 800-1200+ pounds per cubic yard.
- Rubber Mulch: This is made from recycled tires. It is very heavy compared to wood mulch. It can weigh 1000-1800+ pounds per cubic yard.
- Gravel or Stone: This is much heavier. A cubic yard can weigh 2000-3000 pounds or more. But this is often called aggregate, not mulch in the gardening sense.
Moisture Content
This is perhaps the most important factor causing weight changes for organic mulches (wood, bark, needles).
Dry mulch is much lighter than wet mulch.
Wood and bark soak up water like a sponge.
Rain, irrigation, or being stored outside can make mulch very wet.
Water is heavy. One gallon of water weighs about 8.3 pounds.
A cubic yard of mulch can hold many gallons of water.
If a cubic yard of mulch soaks up 50 gallons of water, that adds over 400 pounds to its weight (50 gallons * 8.3 lbs/gallon = 415 lbs).
This is why the weight of wet mulch can be double or more the weight of dry mulch.
A cubic yard of dry wood chips might be 400 lbs.
That same cubic yard soaking wet could be 800 lbs or more.
Density and Compaction
How tightly the mulch is packed also matters.
Loose, fluffy mulch has more air space. It weighs less per cubic yard.
Compact mulch has less air space. It weighs more.
When mulch sits for a long time, it can settle and become more compact.
Different types of mulch compact differently. Shredded mulches can sometimes compact more tightly than chunky chips.
Particle Size and Shape
The size and shape of the mulch pieces affect how they fit together.
Smaller, uniform pieces might pack more densely.
Larger, irregular pieces might leave more air pockets.
This is a smaller factor than type or moisture, but it plays a role in the final cubic yard mulch weight.
Typical Weight Ranges for Mulch
Because of these factors, the weight is always a range. Here are some common estimates. Remember, these are rough numbers.
| Mulch Type | Condition | Estimated Weight Per Cubic Yard (Pounds) |
|---|---|---|
| Wood Chips | Dry | 400 – 600 |
| Wood Chips | Wet | 600 – 1000+ |
| Shredded Bark | Dry | 400 – 700 |
| Shredded Bark | Wet | 600 – 1100+ |
| Pine Bark | Dry | 400 – 650 |
| Pine Bark | Wet | 600 – 1000+ |
| Pine Needles (Straw) | Dry | 200 – 300 |
| Pine Needles (Straw) | Wet | 300 – 500 |
| Compost/Soil Blend | Varies | 800 – 1200+ |
| Rubber Mulch | Varies | 1000 – 1800+ |
Note: These are just estimates. Actual weight can vary.
Weight of Mulch Per Cubic Foot
Sometimes, you might want to know the weight per cubic foot. This is useful if you are using bags (often sold in cubic feet) or loading smaller containers.
We know 1 cubic yard = 27 cubic feet.
To find the weight per cubic foot, divide the weight per cubic yard by 27.
Let’s use the ranges from the table as examples:
Calculating Weight Per Cubic Foot
-
Dry Wood Chips (using a range of 400-600 lbs/yard):
- Minimum: 400 lbs / 27 cubic feet = About 14.8 pounds per cubic foot.
- Maximum: 600 lbs / 27 cubic feet = About 22.2 pounds per cubic foot.
- So, dry wood chips weigh about 15-22 pounds per cubic foot.
-
Wet Shredded Bark (using a range of 600-1100 lbs/yard):
- Minimum: 600 lbs / 27 cubic feet = About 22.2 pounds per cubic foot.
- Maximum: 1100 lbs / 27 cubic feet = About 40.7 pounds per cubic foot.
- So, wet shredded bark can weigh about 22-41 pounds per cubic foot.
-
Dry Pine Needles (using a range of 200-300 lbs/yard):
- Minimum: 200 lbs / 27 cubic feet = About 7.4 pounds per cubic foot.
- Maximum: 300 lbs / 27 cubic feet = About 11.1 pounds per cubic foot.
- So, dry pine needles weigh about 7-11 pounds per cubic foot.
This gives you an idea of how much a smaller amount weighs. This weight of mulch per cubic foot is helpful for filling wheelbarrows or spreading.
Estimating Mulch Weight for Your Project
You won’t have a scale big enough for a cubic yard of mulch. But you can make a good guess.
Check the Mulch Type
What kind of mulch is it? Is it wood chips? Is it shredded bark? Is it pine needles? Different types have different starting weights. Look at the typical ranges for that type.
Look at the Moisture Level
Is the mulch covered? Has it been raining? Is it wet to the touch?
- If it’s very dry, use the lower end of the weight range for that type.
- If it’s damp, use the middle of the range.
- If it’s soaking wet, use the higher end of the range, or even add more weight depending on how wet it is. Mulch sitting in a wet pile after heavy rain will be very heavy.
Consider the Source
Where are you getting the mulch?
- Bulk from a landscape supplier: Ask them! They often know the typical weight range for their specific products. They might even be able to tell you if a batch is unusually wet.
- Bagged mulch: The bag usually tells you the volume (e.g., 2 cubic feet). It might also list a weight range or a typical weight for that size bag. Remember, bagged mulch can also get wet if stored outside.
Use an Online Mulch Weight Calculator
You can often find a mulch weight calculator online.
These tools usually ask for:
* The type of mulch (wood chips, bark, etc.)
* Sometimes, the condition (dry, damp, wet)
* The volume (cubic yards or cubic feet)
The calculator will give you an estimated weight based on typical densities for that material and moisture level. It’s a quick way to get a ballpark number.
Practical Uses of Knowing Mulch Weight
Knowing the cubic yard mulch weight helps in many real-world tasks.
Transporting Mulch
This is where weight is critical. Vehicles have weight limits.
- Pickup Trucks: The amount a pickup truck can carry depends on its size and type (light-duty, heavy-duty).
- A standard half-ton truck might carry about 1000-1500 pounds safely.
- A three-quarter-ton or one-ton truck can carry more, maybe 2000-3000+ pounds.
- Since a cubic yard of mulch can easily weigh 500-1000+ pounds, a half-ton truck might only be able to carry one to two cubic yards, especially if it’s wet. A heavy-duty truck could potentially carry more.
- Always check your vehicle’s payload capacity in the owner’s manual. Do not overload your truck. It is unsafe and can damage the vehicle.
- Trailers: Trailers also have weight limits. Make sure the trailer and the towing vehicle can handle the load.
- Delivery Trucks: Landscape suppliers use large trucks. They are built to carry heavy loads. But even they have limits. They calculate how many cubic yards they can haul based on the estimated weight of the material, especially for heavy things like soil or stone. Knowing the bulk mulch weight helps the supplier schedule and load correctly.
Calculating Delivery Costs
Some suppliers charge based on the weight delivered, not just the volume. Or they might have a maximum weight per delivery trip. If you order a large amount of heavy, wet mulch, it might require more trips than if you ordered the same volume of light, dry mulch. This affects the final cost.
Spreading and Moving Mulch
Moving mulch from the pile to your garden beds is hard work. Knowing the weight helps you understand the effort needed.
- Wheelbarrows: A standard wheelbarrow holds about 2-3 cubic feet of material.
- We calculated that mulch weighs about 7 to 41 pounds per cubic foot, depending on type and wetness.
- So, a full wheelbarrow could weigh anywhere from (2 cu ft * 7 lbs/cu ft) 14 pounds (very light, dry pine needles) to (3 cu ft * 41 lbs/cu ft) 123 pounds (heavy, wet shredded bark).
- This is just the weight of the mulch! Add the weight of the wheelbarrow itself.
- Moving 100+ pounds in a wheelbarrow is a significant task. Knowing the weight helps you plan how many people you need or how many trips you will make.
- One cubic yard is 27 cubic feet. If your wheelbarrow holds 3 cubic feet, that’s 9 wheelbarrow loads by volume. But if the mulch is heavy, you might only fill the wheelbarrow halfway to make it manageable, doubling the number of trips needed by weight.
- Shoveling: Wet, heavy mulch is much harder to shovel than dry, light mulch.
Ordering the Right Amount
While mulch is sold by volume (the cubic yard), thinking about the weight can prevent problems. If you’re close to the limit for your truck or trailer, it’s better to order a bit less or plan for two trips, especially if the mulch looks wet. Don’t just assume a cubic yard is always 500 lbs.
Interpreting Mulch Weight Information
When a supplier gives you a weight for mulch, remember it is usually an average or an estimate.
Mulch is a natural product. Its exact makeup and moisture level change all the time.
The weight listed is a good guide.
If you are right at the edge of a vehicle’s weight capacity, be cautious. Assume the mulch might be heavier than the average estimate, especially if it looks wet or feels dense.
Why the Range is Wide
The wide range (400 to 800+ pounds per cubic yard) shows how much moisture and material type matter. Don’t expect the weight to be exact.
It’s like asking how much a person weighs. It depends on many things!
Focus on the factors that change the weight:
* What kind of material is it?
* How wet is it?
This will give you a better idea of where the actual weight will fall within the range.
Comparing Bagged Mulch Weight to Bulk
Bulk mulch is sold by the cubic yard. Bagged mulch is sold by the cubic foot or cubic foot increments (like 2 or 3 cubic feet).
Knowing the weight of mulch per cubic foot (calculated earlier) helps compare.
A 2 cubic foot bag of dry wood chips might weigh around 30-45 pounds (15-22 lbs/cu ft * 2 cu ft).
A 2 cubic foot bag of wet shredded bark could weigh 45-80 pounds (22-41 lbs/cu ft * 2 cu ft).
A cubic yard is 27 cubic feet.
If you buy 2 cubic foot bags: 27 cubic feet / 2 cubic feet/bag = 13.5 bags. You’d need 14 bags to get one cubic yard volume.
If each bag weighs 50 pounds (a common weight for a 2 or 3 cu ft bag that’s slightly damp), then 14 bags would weigh 700 pounds (14 bags * 50 lbs/bag). This is right in the middle of the typical 400-800 lb range for a cubic yard.
Bagged mulch weight is often more consistent for that specific product because it’s processed and packaged. But like bulk mulch, it can still get heavier if the bags get wet outside.
Summary of Key Weight Points
- A cubic yard of mulch weighs about 400-800 pounds on average.
- Type of mulch (wood chip, bark, pine, etc.) changes the base weight.
- Moisture level (how wet it is) is the biggest factor changing the weight from dry to wet. Wet mulch is much heavier.
- 1 cubic yard = 27 cubic feet.
- The weight of mulch per cubic foot is roughly 15-40+ pounds, depending on type and wetness.
- Always consider the weight for transport (truck limits, trailers).
- Use the weight estimate to understand the effort needed to move and spread it.
- Ask your supplier for their specific product’s estimated weight range.
Frequently Asked Questions (FAQ)
How many pounds does a cubic yard of mulch weigh?
It weighs about 400 to 800 pounds. It depends on the kind of mulch and how wet it is.
What is the average weight of a yard of mulch?
The average is often cited around 500-700 pounds, but this can change a lot based on moisture.
Does wet mulch weigh a lot more than dry mulch?
Yes, much more. Water adds significant weight. Mulch can easily double its dry weight when it’s soaking wet.
How much does a cubic foot of mulch weigh?
A cubic foot of mulch weighs about 15-40 pounds. It depends on the type and how wet it is.
How many cubic yards of mulch can a pickup truck carry?
This depends on the truck’s weight limit (payload capacity) and the mulch’s weight. A half-ton truck might carry 1-2 cubic yards safely. A heavier truck might carry 2-3 yards. Always check your truck’s manual and the estimated mulch weight.
How many wheelbarrows are in a cubic yard of mulch?
A standard wheelbarrow holds about 2-3 cubic feet. A cubic yard is 27 cubic feet. By volume, that’s 9 to 13.5 wheelbarrows. However, because of weight, you might not fill the wheelbarrow completely, meaning you’ll need more trips.
Is bagged mulch sold by weight or volume?
Bagged mulch is usually sold by volume (cubic feet). The bag will list the volume. However, the actual weight of the bag will vary depending on how wet the mulch inside is.
How do I use a mulch weight calculator?
A mulch weight calculator online will ask for the type of mulch and the amount you need (cubic yards or cubic feet). Some might ask if it’s dry or wet. It uses typical densities to give you an estimated total weight.
Why is shredded bark mulch weight sometimes heavier than wood chips?
Shredded bark can sometimes hold more moisture or compact more densely than chunky wood chips, making it heavier per cubic yard when wet or compacted.
How much does pine mulch weigh per yard?
Pine bark mulch weight is similar to other bark or wood chips, around 400-650 lbs dry. Pine needles (pine straw) are much lighter, often only 200-300 lbs dry per cubic yard.
Knowing the estimated weight of your mulch helps you make smart choices for buying, moving, and using it in your yard. Always be safe and avoid overloading vehicles or yourself.
