I’ve tried a mixture of fruit, flowers and herbs in an allotment environment and it does work but is quite difficult to manage. In terms of no dig, after a first thick mulch all over I mulched each time I took plants out. My problem was remembering where I had planted things and therefore being able to harvest at the optimum time. Also I found it difficult to find room to plant things like brassicas for the winter as my system rather lacked any planning.
I now work with a series of patches approx 1 .2m x1.2m which I find I can plan better for follow on crops – each patch has a different veg or flower in and some patches have perrenial herbs and I can also rotate the patches each year. It works quite well but I do have to think about the shade that some crops cast over others. I wish you good luck and lots of enjoyment finding a system which siuts you.
