Why These Names Are Not Describing the Same Thing
Pull up a bulk price list and you will usually see loam, screened topsoil, 3-way blend and garden mix stacked in a single column with a price beside each one. The layout makes them look like tiers of the same product, cheapest at the top, best at the bottom. That is not what is going on. Those four words are not four grades of soil. They are labels from three different systems that happened to end up on the same page.
Loam is a texture class. It describes the proportion of sand, silt and clay particles in the mineral part of the soil. That is all it describes. Loam tells you how the material will drain, how it will pack down, how it will feel in your hand. It tells you nothing about how much organic matter is in there. A soil can be textbook loam and still be close to lifeless as far as plants are concerned.
Garden blend, garden mix, 50/50, 70/30. Those are recipes. The number is a ratio, and the thing being measured is how much compost got mixed into the soil. A recipe name says nothing reliable about the mineral texture underneath the compost. The base could be a nice sandy loam or it could be heavy, sticky stuff that was screened and blended to hide it.
Screened is neither of those. It is a processing step. The material went across a screen and the rocks, roots and hard clods bigger than the mesh got pulled out. Screened is a size spec. It is not a quality grade, and it does not mean the soil is rich.
Key takeaway: you are actually choosing along two separate axes at the same time, mineral texture and organic content, and each product name only reports on one of them. That is why the price column is misleading. The expensive material is not better, it is different.
The practical fix is short. When you call the yard, ask two questions. What is the sand, silt and clay character of the base soil in this product. And roughly what share of it is compost. A yard that mixes its own material can answer both in about fifteen seconds. If nobody can answer either one, that tells you something too.
Loam and Screened Topsoil: The Structural Workhorses
Plain loam and basic screened topsoil sit at the cheap end of the list and move in the highest volume. People read that as the budget compromise. It is not. Mineral-dominant soil is the correct material for a whole category of jobs, and paying more would make those jobs worse, not better.
The reason is stability. Soil that is mostly mineral compacts predictably and then stays where you put it. It has already done most of the decomposing it is ever going to do. Nothing in it is going to rot away and leave a void.
Sandy loam and why it holds a shape
Sandy loam is the standard pick for building up grade, mounding, and filling low spots. It packs, it drains reasonably, and it holds the shape you rake it into. If you are raising a section of yard by four inches, or building a gentle berm, or correcting a spot where water pools against a foundation, this is the material.
Compost-rich blends behave the opposite way. Organic matter breaks down, and as it breaks down the material loses volume. That is the mechanism behind a very common complaint. Somebody fills a whole bed with garden mix, it looks great in May, and two seasons later the surface has dropped noticeably below the edging. A loam base under the same bed would not have moved. Nothing was in it to disappear.
Screened vs. unscreened, and when unscreened is fine
Screened soil is what you want any time you need to rake the surface level or spread the material thin. Unscreened topsoil is full of rocks, root chunks and clods. Every one of them fights a rake, and in a seedbed they show up as high spots, bare patches and things you trip over with the mower a year later.
Unscreened is perfectly acceptable, and cheaper, when nothing is going to be planted in the top few inches. Deep backfill. Filling in behind a retaining wall. Bringing a large low area up most of the way before you cap it with something finer. There is no reason to pay for screening on material that is going to be buried under a foot of other soil.
The honest limitation on both of these is nutrition. Plain loam and basic screened topsoil are thin food for plants. They support roots, they hold water at a reasonable rate, and they give a lawn something firm to sit on. They do not feed anything particularly well without amendment. That is not a defect. It is just the boundary of what the product is for.
Garden Blends: What the Ratios Actually Mean
A garden blend is topsoil with compost mixed into it, and when a number appears in the name, that number is usually the ratio. A 50/50 mix is roughly half compost by volume. A 70/30 leans harder on the soil side, so it is denser and less rich. The higher the compost share, the lighter the material feels, the more moisture and nutrients it holds, and the more it is going to settle over time.
Three-way blends usually combine soil, compost and sand. The sand is there for drainage, the compost for organic matter, the soil for body. A 3-way tends to run denser than a 50/50 garden mix but lighter and richer than plain screened topsoil, which puts it in a useful middle spot for beds where you want good structure and decent fertility at once.
Now the warning that the price list will not give you. More compost is not automatically better. A very rich blend spread as a lawn base gives you a spongy surface that dips where you walk and holds water in low spots. Rich material under sod is one of the most common reasons a new lawn looks wavy by midsummer. For a rooting medium in a raised bed, rich is right. For a surface people walk on, rich is a problem.
Ratios also are not standardized across suppliers. There is no governing body that decides what garden mix means. One yard's garden mix can be noticeably richer than another yard's, and both are labeled honestly by their own standard. This is why the label is not the thing to trust. Look at the material, or ask what went into it.
When the truck dumps, spend a minute on the pile before you start moving it. Good compost-blended soil smells earthy and clean, and a handful crumbles apart when you squeeze and release it. A sour, ammonia-ish or swampy smell means the compost is not finished and is still actively breaking down, which can tie up nitrogen and burn tender roots. A greasy, sticky feel that holds a fingerprint like modeling clay means the base is too clay-heavy for what you are about to plant in it.
Match the Material to the Job
New lawns, sod prep and leveling
For building and leveling grade, use sandy loam or screened topsoil. A firm mineral base is the only thing that keeps a lawn flat over the long term. Get the grade right, roll or tamp it, and it will still be right in five years.
Sod in particular wants a firm, screened, rake-smooth surface. Sod is heavy, and it gets watered hard for the first couple of weeks. Any soft, compost-heavy pockets underneath will compress unevenly under that weight and water, and you get visible dips within the first month. Firm base, thin seams, flat lawn.
Overseeding and thin-patch repair are the exception. There you want a light topdressing of a soil and compost mix, raked in maybe a quarter inch deep. That gives the seed contact with soil and helps hold moisture during germination without changing the grade underneath.
In-ground planting beds
You already have soil here, so the job is amending, not replacing. Work compost or a rich garden mix into the top several inches of the existing ground with a fork or a tiller. Do not just dump a fluffy layer on top of untouched, compacted dirt and plant into it.
The reason is what happens at the boundary. A pocket of very light material surrounded by dense clay acts like a basin. Water moves quickly through the loose stuff, hits the clay, and stops. Roots sit in it and drown. Blending the material into the native soil, and feathering the transition especially at the edges of the bed, gives water somewhere to go.
Raised beds
Here a garden blend or a 50/50 mix is the right call. You are building a rooting medium from scratch, the frame handles drainage for you, and the plants you are growing in a raised bed are usually hungry annuals and vegetables that want the organic matter. This is the job the product was designed for.
Pots and containers
Bulk garden blend is the wrong material for pots, and this is the one place where bagged is simply the correct answer. Bulk soil is too heavy and drains too slowly in a container. Without the surrounding ground to pull water away, it stays saturated, packs down into a dense brick, and the roots suffocate.
Containers need a bagged potting mix built around bark, perlite or coir. Those ingredients keep air space in the pot even after repeated watering. And this holds no matter how rich or expensive the bulk soil is. Small pots especially will compact and stay wet with any bulk material.
The Layering Trick That Saves Real Money
Here is the direct answer to the price question underneath all of this. If a job needs a lot of volume, you do not have to buy the expensive blend for all of it.
Fill the bottom two thirds of a raised bed, or the bulk of a deep regrade, with plain loam or screened topsoil. Then cap the top six to twelve inches with garden blend. Most annual and vegetable roots do their real work in that top layer anyway, and the plants that root deeper will find their way down into mineral soil, which is what they do in the ground.
Layering has a second benefit beyond cost. A bed built this way settles less overall, because the structural layer underneath is not breaking down. Only the cap loses a little height, and you top that up with a fresh inch each spring, which you were going to do regardless.
The other approach is to order plain screened soil and compost separately and mix your own blend on the driveway. It is more shovel work. In exchange you control the ratio exactly, you can see both ingredients before they get combined, and it often lands cheaper per yard than a pre-mixed product.
If you go that route, start conservative. A modest share of compost worked into topsoil is plenty for most planting beds. Compost is easy to add next year as a topdressing and close to impossible to take back out once it is mixed in.
One more line on that. Compost is an amendment and a topdressing, not a soil. Planting directly into pure compost is too rich, too unstable, and it will slump dramatically as it finishes breaking down.
Ordering Smart: Quantity, Access and What to Ask
Start with finished depth, because depth is what drives the number more than area does. A cubic yard spread thin covers a lot of ground and the same yard spread thick covers very little, so decide how deep you want the finished surface before you calculate anything. Measure the area, pick the depth, then work out the volume.
If you are layering, order the structural soil and the blend as two separate drops, and say so when you place the order. Otherwise you can end up with one combined pile and no way to separate it. Tell the yard where each pile goes. It is also worth checking what forms of bulk topsoil and garden soil a given yard actually carries before you commit to a layering plan, since not every supplier stocks a plain screened option alongside the blends.
Account for settling. Anything with meaningful compost in it is going to lose height. Fill raised beds slightly proud of the rim rather than level with it.
Think hard about the drop spot, because soil is much heavier than mulch, especially wet soil. A yard of damp topsoil is a genuinely serious wheelbarrow load, and the distance from the pile to the bed matters far more than it does with bark. Get the truck as close to the work as the driveway and the overhead clearance allow.
Timing matters too. Soil handled wet smears, clumps and compacts, and clay-heavy material is the worst offender. If you can wait for a dry window, wait. Working dry soil is faster, lighter and better for the finished structure.
The decision rule, in one line. Cheap loam for structure and volume, garden blend for the root zone, bagged mix for containers.
How We Started
We started Mulch Mound because we got tired of the hassle that came with buying landscaping materials. The options were either loading bags into your car at a garden center or calling around to local suppliers, trying to figure out pricing, minimums, and delivery schedules. Neither option felt convenient or transparent.
Three of us – Alec, Mo, and Tyler – decided there had to be a better way. Alec and Tyler got their start back in 2013 running a landscaping business during college, moving mulch and mowing lawns to pay tuition. That experience taught them how frustrating it was to source materials, and years later, that frustration turned into Mulch Mound.
We focus on making it simple to get mulch, stone, and soil delivered directly to your home. Order online, pick your delivery date, and we handle the rest. No loading bags. No calling multiple suppliers. No wondering if you bought enough or paid a fair price.
We work with quality local suppliers in the areas we serve and aim to be straightforward about what we offer and what it costs. Landscaping is hard work. Buying the materials for it shouldn't be.
Frequently asked questions
Is loam the same thing as topsoil?
No, and the confusion causes real problems. Topsoil describes where the material came from, the upper layer stripped off a site. Loam describes the particle mix of sand, silt and clay. A load sold as topsoil might happen to be loam, or it might be sandy, or it might be heavy clay from a site where that is what the upper layer was.
That is why two topsoil deliveries from two different yards can behave completely differently on the same job. Same word on the ticket, different material in the pile.
How much compost should go into a planting bed?
Work it into the top portion of the bed rather than trying to hit an exact percentage. Precision is not really achievable with a fork and a wheelbarrow anyway. Start conservative, because compost keeps releasing nutrients as it continues to break down, so a bed that looks lean in April is often about right by July.
The better habit is an annual top up. Add a fresh layer each spring and let worms and weather work it down, instead of trying to load the bed with everything it will ever need on day one.
Can I use garden mix to level a lawn?
For filling small depressions in an established lawn, yes. A thin soil and compost mix works fine there, spread shallow enough that the existing grass grows up through it.
For establishing grade across a whole yard, no. Use a mineral soil. A compost-heavy material will keep settling under foot traffic and mowing, and the flat surface you raked in spring will not be flat in two years.
What is the difference between screened topsoil and garden mix on a delivery ticket?
Screening is about what was taken out. Blending is about what was put in. They are independent facts about the same load.
So a screened topsoil can still be perfectly plain with no compost in it, and a garden mix can be screened or unscreened depending on the yard. If the ticket only says one of the two words, you still do not know the other, and it is worth asking.
Do I need to test soil before ordering?
A basic test on your existing ground is worth doing before you spend money on amendments, particularly in a bed that has struggled for a couple of seasons without an obvious cause. It is cheap relative to a soil delivery.
The value is that it separates three different problems that look similar from above. You may need organic matter, you may need a pH correction, or you may just have a drainage issue that no amount of new soil on top is going to fix.
