I've asked a similar question back a ways but I thought I'd ask again with a twist.
The coming year we're looking at starting vegetable gardening, however the soil is all dense-pack clay. We're looking at raised beds - by which I mean building boxes and raising them about three feet off the ground because neither of us can bend over for regular weeding easily.
My back-of-the-envelope calculations show a 1m x 2.5m x .5m box, when full of wet soil, weighs in at just over 1400kg!
Has anyone here raised growing beds this high? What sizes of beds would you recommend?
Thanks!
