It seems to have taken the gardening fraternity a hugely long time to realise that the main reason for digging is to break up the soil compacted by continually walking over it in the first place. Classic books of my childhood such as Middleton's Gardening Guide (2/6d in old money or 12.5 pence in new - paid for out of hard earned pocket money!!) and Arthur Hellyer's The Illustrated Gardening Encyclopedia have no mention whatsoever of the technique of raised beds and both devote quite some space to telling the reader exactly how to dig, and double dig!
And this week I have been up there smartening the paths again, spreading more chippings and generally tidying up. Adding my own compost, fresh manure or rotted manure on top of the soil according to the planned use of the area next year helps to maintain the height of the raised beds above the paths and only needs a light forking in when I am ready to sew or plant or whatever. And harvesting roots etc loosens and works the soil with minimum effort. So - NO DIGGING!
