When we used to cultivate 'Plot Growster' in the eighties, we watched how everyone else did their work, and copied the styles and methods - even asking lots of questions as well.
One system was generally evident, which I still use at the moment, and that is to dig a deep 'kerb' or 'trench' at the perimeter, and gently camber the topsoil to a high point in the middle of the entire plot.
It helps drainage, and also the edges can be trimmed of invading couch from the paths. I find the plot usually looks tidy, and easy to maintain.
But this flies in the face of raised beds, although the principle is not dissimilar!
Although now, I'm looking at ways where other members have described having individual blocks of topsoil - say 4' x 6', and I think it may well work with me. I've always been anti-paths to date, but will still learn from chums here, and if we get the new plot, then I'm probably going to give it a whirl!
They won't be raised beds, as it'll take too much cash to buy the timber, but I reckon a mini-cambered area - say - 4' wide by 14' long, with a mown strip at the edges is a leading option at the moment...
And all this thinking has come from reading posts by everyone here so thank you - the long sleepless nights just fly by...!
