The bed on the left is filled with old soil from a bed I moved, the one on the right is filled with new soil purchased from Living Earth.  I planted 2 varieties of onion, half in each bed.  This should be a pretty good comparison of the two.

I purchased 3 cu-yds of soil from Living Earth in Plano.  Price was $62/yd

I assembled 2 beds from the formed concrete sides I made in the past.  I also built 2 more beds from treated 2×12 lumber.

The beds I made ~8 years ago from cedar are starting to deteriorate to the point they are failing.
