Hello I have a new plot too, so wading in. It's about 15m x 5m, pretty neglected. So far (last couple of weeks) I've stripped back and dug over about 2/3 of it I am tempted by "no dig" but this is riddled with horsetail and not even the greatest no dig advocate suggests that you can beat horsetail with it, so I suspect I have a couple of years at least of dig before I can consider switching. But I'm structuring it in 2m x 2m (ish) beds anyway.
So far I have in broccoli, cauliflower, beetroot, spinach, spring onions, a couple of types of lettuce, potatoes (need to buy more seed potatoes), two types of carrots (one that's apparently good with stony ground), autumn raspberry canes, a couple of blackcurrant bushes and a dwarf apple tree that was in a pot on my balcony and I thought was dead until it suddenly blossomed a week or so ago -- not expecting any fruit off it this year, but it'll be a lot happier in the ground and there are plenty of bees at the allotment so it may even get fertilised next year. I'm planning additional sweetcorn (the packet says to plant it next month if sowing directly outside), pumpkins and quinoa (my mother has some spare seedlings that she's throwing my way).
This is all a bit random this year on a basis of just getting things in so that I manage to harvest something, but I need to work out a proper rotation system for the vegetable beds and want to acquire more fruit bushes next year (gooseberries, at least).
