We had the key holes for a year, and because of wrong sizing did not enjoy
it very much. I see it often, that people try to save space for the
walkways, and oversize the beds, which in combination compromises the whole
idea. Now I have a garden that has free style bed layout according to
grade, existing perennial vegetation, pollination requirements, aspect,
irrigation method and aesthetics. (We could not grow corn happily in a key
hole, but like it grown in a "butterfly" bed - two key holes attached on
the exterior edge. )
The principle of "increase edge" is still met, the layout in not super
imposed, but rather adopted for my needs.
I also raise beds by excavating the top soil from the paths, and then sheet
mulch and add 2-3' of shredded wood to raise the level of the walkway, as
we live in desert, and a true raised bed is not a good idea.
I have not done it yet, but I am sure it is possible to make a good
"increased edge" garden in conditions of flood irrigation, as the water
also benefits from moving in not-so-straight lines, as it aerates, and
deposits its silt load more evenly. The walk way then will serve the
function of water channel as well, and I heard of some amazing gardens,
that had small bridges and decks so one can walk over the moving water, and
keep the weed at bay, and the irrigation going.

Why is that? The only reason my first herb spiral is abandoned, is that we
moved to a new place. I also have seen this idea adopted to different
environments, like half spirals attached to a wall, or free shape multiple
level beds around fixed objects (trees, poles, etc)
I think the problem is that we take some things as directions and the only
solutions, when they are only examples. I feel less and less comfortable
to give our students any plant lists, or examples of lay out of forest
gardens, or gardens, as I see how some people tend to receive it as the
prescribed way of doing it, rather then "a possible way".
What is your experience with it?
