Allotment rotation?

[Louiseness]

Hi guys and girls,

This weekend I'm paying my first visit to my newly-acquired allotment, which I'm sharing with my parents.

I can't tell you much about the allotment size, aspect or even type of soil or anything yet, but I know they're planning on dividing it into four sections with a sort of cross shape of paths between.

I've been reading about crop rotation and looking at plans but I'm having a bit of trouble figuring what should go where as we want to grow things that aren't really included in the ones I've read, like three-year and four year plans.

For example, some of the things we definitely want to grow are:
Potatoes
Peas and beans
Squashes/pumpkins
Parsnips and carrots
Onions and garlic
Probably things like cabbages/cauliflowers/broccoli or salad leaves too

Plus I have 8 raspberry canes and some strawberry plants in containers which I'd really like to plant out too. I know strawberries need to be replaced every 3 years or so so that's making me even more confused!

Any suggestions for what sort of plan we should follow and what should go where in the 4 potential quarters? The first things that will be going in are the strawberries and raspberries, then probably garlic and overwintering onions soon, so everything else can really be built around those.
