Understanding Cubic Feet and Cubic Yards

Many gardeners encounter both cubic feet and cubic yards when purchasing soil.

Cubic Feet

Smaller soil quantities are often sold in cubic feet.

Example:

Add Extra Soil if Needed

Soil naturally settles over time. Consider purchasing slightly more than the estimated amount.

Consider Soil Type

Different projects may require:

  • Topsoil
  • Garden soil
  • Compost blends
  • Raised bed mixes

Plan for Future Growth

Vegetable gardens often benefit from deeper soil layers for healthy root development.

Compare Bagged vs Bulk Soil

Large projects are often more cost-effective when purchasing bulk soil rather than individual bags.


Advantages of Proper Soil Planning
