Not all topsoil is the same. Suppliers carry different grades and blends, each suited to specific projects. The six main types are unscreened topsoil, screened topsoil, blended topsoil, sandy loam topsoil, black dirt topsoil, and organic/compost-rich topsoil. Choosing the right type can save money on cheap projects and dramatically improve results on planting projects. Here’s what each type is, what it costs, and when to use it.
The 6 main types of topsoil
1. Unscreened topsoil
Natural topsoil dug from the source without sifting or processing. Contains everything that was in the original soil — rocks, roots, twigs, occasionally trash. Cheapest topsoil option.
- Cost: $10-25 per cubic yard
- Best for: Fill, grading, foundation layers below the planting zone
- Avoid for: Planting beds, lawn establishment, garden use
- Quality variance: High — quality depends entirely on the source
2. Screened topsoil
Natural topsoil sifted through a ½ or ¾ inch screen to remove rocks, roots, and debris. The standard retail product. Uniform texture, easier to work with than unscreened.
- Cost: $20-40 per cubic yard
- Best for: General landscaping, lawn projects, mixed planting beds
- Note: Screening removes physical debris but doesn’t change soil composition or fertility
For full detail on screening, see our screened vs blended topsoil guide.
3. Blended topsoil
Screened topsoil mixed with compost and/or other amendments to improve growing performance. Common blends include 70% topsoil + 30% compost, or 50/50 topsoil/compost ratios.
- Cost: $35-70 per cubic yard
- Best for: Vegetable gardens, raised beds, ornamental beds where soil quality matters
- Note: Verify the actual blend ratio with the supplier — “blended” can mean anything
4. Sandy loam topsoil
Topsoil with a specific texture: roughly 60% sand, 25% silt, 15% clay. Excellent drainage with adequate moisture retention. Considered the ideal soil for most plants.
- Cost: $35-55 per cubic yard
- Best for: Vegetable gardens, root crops, fruit trees, lawns, perennial beds
- Note: “Sandy loam” should match real soil texture standards — see our sandy loam guide
5. Black dirt / muck topsoil
Very dark topsoil with extremely high organic matter content, often from wetland or former-lake-bed sources. Sometimes sold as “black topsoil” or “muck.”
- Cost: $30-60 per cubic yard
- Best for: Amending existing soil, adding organic matter to garden beds
- Watch out for: Very high water retention — can be too wet for some applications. Often acidic.
- Use in moderation: Mix 25-50% with standard topsoil rather than using pure
6. Organic / compost-rich topsoil
Premium topsoil with 15-25% organic matter content (vs 3-6% for standard topsoil). Often certified organic and tested for contaminants.
- Cost: $50-100 per cubic yard
- Best for: Organic vegetable gardens, high-value ornamentals, raised beds where premium quality justifies cost
- Note: Look for OMRI listed or USDA Organic certified options
Comparison table: all 6 types at a glance
| Type | Cost/yd | Organic Matter | Best For |
|---|---|---|---|
| Unscreened | $10-25 | Variable | Fill, grading |
| Screened | $20-40 | 3-6% | General landscaping |
| Blended | $35-70 | 10-20% | Vegetable beds, raised beds |
| Sandy loam | $35-55 | 3-6% | Most vegetables, fruit trees |
| Black dirt | $30-60 | 25-50% | Soil amendment (use in moderation) |
| Organic/compost-rich | $50-100 | 15-25% | Certified organic gardens |
How to choose the right topsoil for your project
Filling low spots or grading a yard
Use unscreened topsoil. The debris doesn’t matter beneath the planting zone, and you save 30-50% on material cost. Cover with a top layer of screened topsoil if grass will eventually grow there.
Establishing a new lawn
Layer approach: 3-4 inches of screened topsoil as the foundation, 1-2 inches of lawn soil blend on top. See our lawn soil vs topsoil guide.
Vegetable garden
Use blended topsoil or sandy loam with compost amendments. Aim for 10-20% organic matter content. For raised beds, fill with a 70/30 blend of topsoil and compost.
Building a perennial flower bed
Blended topsoil works well. The compost component supports vigorous flowering and extends the productive life of the bed.
Container or potted plants
None of these — use potting soil instead. Topsoil compacts too much in containers. See our topsoil vs potting soil guide.
Tree backfill when planting
Use screened or sandy loam topsoil mixed with the existing native soil (50/50). Trees need to root into the native soil, so pure premium topsoil can actually slow root spread.
Regional variations in topsoil availability
The types and quality of topsoil available vary significantly by region:
- Midwest: Excellent natural topsoil from former prairie land; sandy loam common
- Southeast: Often clay-heavy native soil; screened topsoil widely available
- Northeast: Rocky native soil; screened topsoil necessary; higher prices
- Pacific Northwest: Volcanic-derived topsoil; often acidic; mostly amended for retail
- Southwest: Low-organic-matter native soil; most retail topsoil is heavily blended
- Mountain West: Limited natural topsoil; most products are blended or imported
What about specialty topsoil?
Some suppliers offer specialty products beyond the six main types:
- Mushroom soil/compost: Spent substrate from mushroom farms. Used for amendment.
- Garden soil: Similar to blended topsoil but typically pre-mixed for retail bag sales
- Topdressing mix: Finely-screened blends for lawn topdressing
- Bioretention soil: Specially designed for rain gardens and stormwater management
- Turf-grade topsoil: Sand-heavy blend specifically for sports fields and golf courses
Frequently asked questions
Which type of topsoil is best for a vegetable garden?
Blended topsoil (70% screened topsoil + 30% compost) or sandy loam topsoil with added compost. The combination of structure, drainage, and organic matter supports the widest range of vegetables.
Is more expensive topsoil always better?
For planting projects, generally yes — better-quality topsoil with more organic matter produces better results. For fill projects or foundation layers, no — premium topsoil is wasted below the planting zone.
Can I mix different types of topsoil?
Yes. A common approach: use cheaper screened or unscreened topsoil for the bottom 60-70% of fill, then top with premium blended or sandy loam topsoil for the planting zone.
How can I tell what type of topsoil a supplier is selling?
Ask for a sample, then evaluate: color (dark = more organic matter), texture (the ball/ribbon test reveals sand/silt/clay ratio), debris (rocks indicate unscreened). Don’t rely on labels alone.
Is black dirt the same as topsoil?
Not exactly — “black dirt” usually refers to high-organic-matter soil from wetlands or former lake beds. It IS a type of topsoil, but with much higher organic content than standard topsoil (25-50% vs 3-6%).
