I have known about no dig for a few years now but have only managed to get started properly recently.
I prepared my small plot in December, placing cardboard then covering with store bought peat-free compost.
I have had to make an addition of a net cage as the local gang of jackdaws find it amusing to pull out my seedlings.
I also have a small willow tree in my plot! I couldn't think of anywhere to transplant it to, so decided it could stay and get surrounded by veg. 😁
I have Charles' calendar and follow the planting guides to help me get timings right. I also find his YouTube videos really helpful.
