1.
Start by putting together the two east/west sidepieces from 2x2s.
I used 28" long pieces for the horizontals and 36" pieces for the
verticals. Each side has TWO verticals at each end.
2.
The boards for the north and south sides slide between these
verticals, supported by small L brackets. Be sure you leave
enough room for the combination of brackets and boards but not
too much. I used L brackets that had a real dimension of about
3/4", so I left exactly 1 inch between the verticals, and that
worked very well.
2
Measure up from the bottom horizontal in order to figure out
where the first bracket should go, and then up again for the next
bracket, and so on. Your measurements for bracket position will
vary depending on the size of boards you use. I used 1 x 8 boards
(which are really only 7 3/8”, not 8") and allowed 7.5" measured
between bracket screwholes. Do a test with a small section of
board to ensure that your calculations will work with your
materials! Once the measuring is done attach the brackets, and
screw the 2x2s together.
3.
Next screw one or two boards to the frame to make the base of a
solid side and give the structures some stability. These boards
should rest on the bottom horizontal 2x2 of the frame and only
go to the width of the inner verticals of each pair. When you
build above the boards that are screwed into place, you should
be able to do it by resting the boards on top of each other and
relying on the weight of the dirt to hold them in place.
4.
Once you've got the east and west sides built, connect them
using a single 2x2 bar at the top, attached to each side by a bolt
run through drilled holes.

I ran additional connectors on both sides of the bottom and fit
them above the horizontal 2x2s on the bottom of the east/west
sides, just outside where the loose boards fit. Drill holes through
them for bolts to drop through.
Because the 2x2 underneath has a screw through it forholding
the vertical 2x2s in place, you can't drill a hole right through it,
but I could drill in about half an inch, and that seems to be
enough to keep the pieces in place.

Untested modification: shove the two stabilizing 2x2s right up
against the sideboards—this should provide room for the drill
hole to go through the space between the screws holding the
vertical 2x2s in place.
Slide in the first loose boards on north and south (in the
modification they’ll rest on top of the stabilizing bottom 2x2s
instead of the bottom horizontal 2x2) and then build them up
with the rest of the box as the project proceeds.
