Where do you even start, anyway?

So my first working trip to the allotment today. I didn't do too much, honestly, I needed a spade and I hadn't brought it along, and frankly, I didn't want to dig enough to walk the ten minutes home to fetch it. In all fairness, I was expecting to dig the little patch that I had nominated as my first job with a fork because I assumed the soil might be bad and sticky. I was surprised the soil was nice and crumbly. There's a bit of me that thinks that I don't have to dig it over or do very much at all, just add some soil and some fertiliser and dig it in, but I'm kidding myself, out of choice. Anyway, the sun was out and I quite enjoyed just sitting on a patch of couch grass and enjoying the fresh air.

The bed was covered in couch grass obviously, as every single uncovered inch of the plot is, and it was harder than I anticipated getting rid of it, although I suspect some of the problem was the tiny size of the bed that the last tenant had made out of tiles.It was hard, and I'm not that strong. I have a grub hoe, or azada, which I could get better at  using and then acually cut through the bloody stuff. Even when I have dug it up, I dont know what to do with the couch grass, I want to compost it but I know that I have to either drown it or compost it for a couple of years before I can use it in a normal bin or on the plot or its just going to resprout. I have at least two bins, as I've said before, so potentially I could use one for 'naughty compost' and one for the safe stuff.
Anyway, once properly cleared, dug over and fed, it will be my first growing space. I'm thinking of tomatoes or herbs. Tomatoes are risky when the summers are cold and damp (often) but I also want to grow tomatillos and I know that toms are a (fruit) veg that my family eat a lot of. I've got some maincrop spuds coming in the post soon. Maybe there isn't enough room though...
So its going to rain a lot of the next couple of weeks. I think that precludes digging (although I might be ok to clear a patch from couchgrass that I plan to cover and forget about for a year, surely?), so I think my allotment time will be mostly based around clearing the flipping brambles that try and trip me up every time I walk across the plot, and cut some planks for the beds I need to terrace. Cold, wet and sawing. Can't wait.
