I started to No Dig without knowing what it was. I was staying in a cabin on the west coast of Scotland during lockdown. Intuitively the best way to create a vegetable patch seemed to be to collect the leaf/seaweed mulch at high tide and use that to smother the weeds.
Since that time I bought my place on Hayling Island and discovered Charles Dowding's videos.
I am no expert but I have grown a lot of different vegetables including a rather excellent red onion crop: planted after we were flooded with seawater for five days in April this year.
