The French Intensive, Double-Dug Raised Bed Vegetable Garden -- useful summary.
However, the best thing I've read is not a website -- although it can be downloaded from the web:
The Market Gardener : A Successful Grower's Handbook for Small-Scal... by Jean-Martin Fortier. DIY manual that covers all the day to day challenges.A great gardening book rooted in the real world.
Bought a book on French Intensive Gardening - sounded brilliant until I read about all the manual labour involved :-(
French Intensive doesn't foster lazy gardening, especially not in the first year.
But I appreciate it because:
Given my conditions and already existing habits I'm thinking that adaptions are required -- tweaks -- but my sandy soil got me thinking that maybe I'm already part of the way there, esp when I'm on my knees sifting cow manure through it. En route I get to free myself from a few Permaculture shibboleths.
As for the labour involved -- let's call it an 'exercise' regime: good honest toil.
Of course a lot of this is about the perspective unfolding in your head -- what you 'think' you are doing. While all these gardening systems have specific merits they do engineer things differently, despite overlapping. Nor do you have to be either/or. Instead of 'one' garden you may end up with several, each ruled by different protocols.One size won't fit all.
Where the French Intensive system edges ahead of these other approaches is in its productivity. It's also rooted in actual urban conditions -- albeit when horses were the primary transport means -- in part as a means to handle waste. Golly if the automobile hadn't come along and the Haber process hadn't invented synthetic fertilisers, we'd still be poo dependent today.
The digging itself disturbs the soil microbes - that's the rub.
