Where do I start?

Because I've managed to get a day of my holiday to myself I have done some brewing stuff and managed to get a pottering hour at the plot. What's still in is growing steadily, some cabbages look like they want harvesting and I'm scared of the parsnips. I'm sure there is a lot to do up there but I can't really work out what. The beds aren't too weedy so I'm really not sure where to start. Essentially I just pottered, watered and picked some tomatoes.

So I think the job for the weekend is to get a list together so we know what needs doing!
