Filling a raised bed
The volume is length × width × depth, and loose soil settles after watering, so a 10 to 20% buffer is common. The raised bed soil calculator and the soil calculator handle that, plus round beds, several identical beds, and bulk versus bagged cost.
Typical soil depths
| Project | Typical depth |
|---|---|
| Raised vegetable bed | 8 to 12 in |
| In-ground garden bed | 6 to 8 in |
After planting, finish beds with the mulch calculator. More calculators are planned, such as plant spacing and raised bed layouts.
