Thank you both 
I’m on the cusp of the south east and west. It’s a newish site, been going less than a year. The plot has been taken back from the guy next to it as they don’t feel he’s cultivated enough of his original plot - raised beds but a lot of grass. The sun sets down one end of it From what I swam I think so will get a decent amount during the day.
Water from a pump and no shed but am allowed one. Long term plan will be to have one which will allow for water collection. Have to apply for permission which I’ll do soon and they want slabs for a base so i’ll see if I can get hold of some cheap ones. Shed won’t go available this year as currently storing building materials in my garden . But figure if I get slabs down it’s less to cultivate.
It does need a fair amount of work, one section isn’t too bad and they’ve said they’ll weedkiller the other bit when weather warmer which I think I’ll run with. Had ideas of doing some no dig beds but cardboard got vetoed annoyingly. I know the site manager from previous allotment days and he knows health situation and said he’ll go easy on me. I said i’ll be looking at doing squash and pumpkins and borlotti beans rather than runners, borlotti were clearly a new one on him!
Have some rhubarb , gooseberries, thornless blackberries, raspberry canes that can go in and there is a small strawberry patch. I’m going to do things that don’t need constant harvesting (courgettes will be done at home!) so sweet corn, perpetual spinach, chard, parsnips (if I can get them to germinate!) possibly oca, leeks, kale as well as pumpkins squash and borlotti. If I end up out of action for longer than a couple of weeks that will help. If all goes well then I can look at other things, main thing is I’m going to have to try and get a good run at it the next 6 weeks or so and will try to get things started at home as much as possible this year - bit of a faff but need instant impact. Very excited and feel a bit like I’ve won the lottery !
