How much soil do I need? (& will it fit in my Prius?)

Posted on Apr 12, 2020 in Growing Help

1. Measure your garden bed:

4’x8’x1’=32cu.ft (1.2cu.yds)

2. Calculate the volume of your bed:

3. Will my soil fit in my vehicle?

Vehicle volume guide:

  • CARS
    • FYI your car will probably only hold up to 10-13 cu.ft of soil max (unless you get really creative). We only sell in bulk so you will need to bring your own containers (or use our recycled bags) and determine your vehicles capacity.
  • SMALL TRUCK (Toyota Tacoma, Nissan Frontier, Ford Ranger, etc)
    • holds up to 1 cu.yd soil or compost, or 1.5-2 cu.yds mulch
  • LARGE TRUCK (F-150, Chevy Silverado, 6 or 8ft bed)
    • holds 1.5-2.5 cu.yds of soil or compost

Basic weights & volumes guide:

  • Weight of soil & compost (depending on moisture):
    • about 30-40 lbs per cu.ft
    • about 1,200-1,700 lbs per cu.yd
  • Weight of wood mulch:
    • about 500-800 lbs per cu.yard
  • Volumes of soil, compost, and mulch:
    • 1 cu.ft = 7.5 gallons
    • 13.5 cu.ft = 0.5 cu.yds (half a small truck load)
    • 27 cu.ft = 1 cu.yd (small truck load)
