in Fruit & veg
I have reached a place in the garden where the soil is not so lush (the garden was neglected for years, and overgrown when I moved here) and so I have decided to have a go at the no-dig method, I have seen the video'sand thought I would have a go myself, I have loosened the ground beneath, however, I wouldn't think a carrot could penetrate it with success, so I will only plant Brassica in this plot and maybe lettuce, I started with 3 layers of Corrugated card, then the frame and finally compost which is 12 cm deep, but I have some more to add to take it to approx 16 cm. Would anyone like to comment?
Brassicas take up a LOT of space and may fall over in shallow compost, you wouldn't get many plants in there.
So perhaps go with carrot and lettuce.
In time the soil underneath should improve if the only lining is cardboard and then you could plant something deeper rooting.
I tried the no dig method last year to create new borders. The ground was hard from foot traffic and I did as you did: cardboard straight on the grass, compost (in my case topsoil/compost mix) on top to depth of 10". I've had no problem putting in 3 litre shrubs and perennials this year (12 months on from when I started) plus a few larger plants. Ground here is very stony and I didn't fancy the effort of stripping the grass and digging it all over.
I've just started a new veg bed in exactly the same way but to overcome lack of space and desire for deeper rooted crops I have placed a smaller frame on top and filled that too. This will enable me to grow parsnips, etc.
