1) This was excerpted from a response to a similar request (i.e., how to
create a regular raised) by Jack Hale, a master gardener and CG garden program
"In our smaller gardens on bad soil, we often build raised beds that are 4'
by 8' and a foot deep. We use recycled plastic landscape timbers that are about
3" thick. It takes 12 timbers, 4 of them cut in half, plus about 30 6"
galvanized twist deck spikes to make one bed. It holds just over 1 yard of soil.
I figure a little over $100 per bed when I'm budgeting. There are cheaper ways
to do raised beds - making them bigger, for instance - but this size is very
solid and easy to build. A group of people can pick them up and move them after
they have been constructed. They make a nice manageable unit within the
Note: The plastic landscape timbers are non-reactive and do not leach
chemicals into the soil. If you choose to use wood - USE ONLY UNTREATED WOOD. NASTY THINGS LIKE ARSENIC AND OTHER
CHEMICALS LEACH INTO THE SOIL FROM ALL PRESSURE TREATED LUMBER, MAKING IT
2) For a senior in a wheelchair, we made an enabled bed in our garden in
brick about 2' high, 3' wide and 9 foot long next to one of our back garden
paths. We may build a hollow square one ( with one of the sides missing) in the
future as an alternative design. Here is the website of the garden I volunteer
