May I suggest poured earth? We are doing a house in poured earth with
18" walls, and will do our raised garden edges with 4" poured earth
walls. Build a form that can be used over and over, put a strip of
Tyvek in the bottom and pour a slurry of local clay + gypsum or cement +
a waterproofer like Ramseal. Our main form will be one segment of a
keyhole garden, so we sequentially pour several segments and then move
on to the next keyhole. We are also building one form to pour straight
walls and one to do a generic S curve. The labor is in the form, so you
want to think through how to build the smallest number of forms.

Re: cob walls
I like this idea. We have Jeavons-style raised beds in our
garden which rests on a mild slope & I always wish the walls
didn't crumble & the bed would keep its original shape.
A big advantage of raised beds is that it allows more air &
more water in the soil but does not get too wet or too dry.
We have a drought going here, but our veggies are doing
OK.
Has anyone tried this cob-type method & does it allow the soil
breath adequately?
Would something cruder, more like mud work pretty
well?
For Pc & Peace,
John
