Topsoil vs. Fill Dirt
They look similar in a pile, but they do different jobs. Here is how to choose, and when to use both.
Choose topsoil for growing
Topsoil
Topsoil has more organic matter and is meant for lawns, gardens and landscape beds. Use it as the top growing layer, where grass, flowers, shrubs or vegetables need nutrients and root support.
It is usually not the economical choice for filling deep holes or raising grade.
TopsoilChoose fill for volume
Fill dirt
Fill dirt goes below the surface to raise grade, fill low spots and build volume where growing plants is not the main goal.
After shaping and compacting fill, add topsoil wherever grass or landscaping will go.
Fill DirtSide by side
| Topsoil | Fill dirt | |
|---|---|---|
| Main job | Growing layer | Volume and grade |
| Organic matter | Higher | Low |
| Typical depth | A few inches on top | As deep as the grade change needs |
| Good for | Lawns, sod prep, beds, gardens | Low spots, pads, rough grading |
| Not ideal for | Deep structural fill | The layer plants grow in |
Often the answer is both
Fill the low area and shape the grade with fill dirt, compact it, then finish with a layer of topsoil for sod or planting. That keeps costs down and still gives grass and plants a good start.
