Sort of with Crystalmoon on this, grow the stuff that you like (make a lsit of what you like) and especially the stuff that's expensive.... I've goto a bit over 10 rods (2x5 plus the garden) and I put 3 rods down to spuds cos I love heritage and baking potatoes... also there's a load of fruit, blackcurrants and a couple of cherry trees... and an asparagus bed.... and I grow a lot of sweetcorn,,,, but it'as a good idea to ahve some winter veg, and salads almost grow themselves in the summer anyway.... grow offbeat stuff too, good for conversation starters on the plot and some of them are really usefuo crops too... saffron, walking onions, etc...
