Topsoil vs. Garden Mix vs. Compost: Which One Do You Actually Need?
Three products, three jobs. They look similar in the pile, but they're built for very different projects. Here's how to pick the right one — and stop guessing on the phone.
The Quick Version
If you just need a fast answer, here it is:
| Product | What It Is | Use It For | Price |
|---|---|---|---|
| Screened Topsoil | Farm loam + compost, screened to 1/2" | Lawns, grading, seed prep, sod base, filling | $45/yd |
| Garden Mix | 50/50 topsoil + compost with 9-0-5 fertilizer | Raised beds, vegetable gardens, flower beds | $48/yd |
| Screened Compost | Pure organic leaf compost, screened to 1/2" | Amending existing soil, enriching beds, topdressing | $45/yd |

Screened Topsoil
A blend of native Connecticut farm loam and organic leaf compost, screened to 1/2". The farm loam gives it structure — it holds its shape when graded, supports root systems, and doesn't wash away in heavy rain. The compost gives it organic matter, color, and nutrients.
Use topsoil when you're creating a new surface layer. New lawns, seed prep, sod base, grading, leveling, filling low spots — any project where you need a clean layer of workable soil on top.
Best For
New lawns, seed prep, sod installation, finish grading, leveling, filling low spots, and any project where you need a standalone growing surface.
Most residential lawn projects use topsoil at 3–4 inches of depth. One cubic yard covers about 100 square feet at 3 inches deep. For a 1,000 square foot lawn, you'd need roughly 10 yards.
Topsoil is the finished product. You spread it, grade it, and plant into it. It works on its own — you don't need to add anything else for a lawn or general planting.
Screened Compost
Pure organic compost — locally collected leaves and clean yard waste, composted at our CT DEEP permitted facility and screened to 1/2". No sewage sludge, no municipal waste. Just decomposed organic material.
Compost is not a standalone soil. It's an ingredient. You don't fill a bed with straight compost and plant into it. You mix compost into existing soil to make that soil better.
Best For
Amending clay or sandy soil, enriching existing garden beds, lawn topdressing after aeration, and boosting organic matter and soil biology.
The Flour Analogy
Think of topsoil as a finished meal. Compost is one of the ingredients in that meal. You wouldn't eat a bowl of flour by itself — but flour makes bread better. Same idea. Compost makes soil better, but it's not soil by itself.
A common mistake is ordering compost when you actually need topsoil. If you're building a new lawn from scratch or filling an area that has no soil, compost alone won't give you the structural base you need. You need topsoil for that. Compost is for improving soil that's already there.
Organic leaf compost produced at our facility — the foundation ingredient in our topsoil and garden mix blends.
Organic Garden Mix
A 50/50 blend of screened topsoil and screened compost with a 9-0-5 slow-release organic fertilizer already mixed in. The higher compost ratio gives it more organic matter, better moisture retention, and a slightly acidic pH that most vegetables and flowers prefer.
Use garden mix when the goal is maximum plant growth. It's the richest growing medium we produce — and the built-in fertilizer means you're not buying soil, compost, and fertilizer separately.
Best For
Raised beds, vegetable gardens, herb gardens, flower beds, and any planting area where you want the best possible growing conditions straight out of the pile.
Garden mix costs $3 more per yard than topsoil. For a 4x8 raised bed, you need about 1–1.5 yards. The price difference on a project that size is negligible — and the growing results are noticeably better.
Don't use garden mix for lawns. It's too rich and too loose for turf grass. Topsoil is the right product for lawn work.
The Decision Tree
Two More Products Worth Knowing About
Top Dress Mix
4 parts topsoil, 3 parts coarse sand, 1 part peat moss. A specialty lawn blend designed for topdressing, leveling, and overseeding prep. It spreads into grass without smothering it. This is what golf courses and professional landscapers use for turf renovation work.
Screened Fill
Subsoil screened to 5/8". Not a growing medium — this is structural base material. Use it to raise grade and fill, then cap with topsoil for the finish layer. Save money by using fill where you need volume and topsoil only where you need growth.
Mix and Match on One Delivery
A lot of projects use more than one product. A common setup for a backyard renovation:
Screened fill for the deep base layer where you need volume — saves money at $20/yard.
Topsoil for the lawn areas on top of the fill.
Garden mix for the raised beds and planting areas.
Add all three to your cart, pick your quantities, and check out. We load them separately so you know which pile is which.
