Thank you all. Very helpful to know it can be flexible. I shall consult your almanac for liming advice Tee Gee.
Our soil is neutral to slightly acid so I've bought some lime as I do grow a lot of brassicas especially cavolo nero and PSB which I can't buy here but I also like to grow Savoy, pointy and red cabbage a well as green broccoli and OH has treated himself to some abominable sprouts this year so I thought it would be advisable to add lime. The chooks love brassicas too, as I've discovered....... so we net against butterflies and hens now.
Other movable favourites are garlic, leeks, shallots, beetroot, fennel and broad beans plus cut and come again salad leaves.
We always add some of our own garden compost when replanting a bed and I bunged a whole trailer load of manure (swapped for eggs with neighbour) for the new, permanent dahlia bed and planted the squashes and courgettes in the spare space. There is a seep hose in there so it'll be good to be able to keep topping up the manure and grow more squashes in there.
Other permanent beds are raspberries, a mixed currants bed which includes a pomegranate and a feijoa now and a dryer bed with green asparagus and globe artichokes. Tried fartichokes but it's too dry here.
Tomatoes and chillies are in the polytunnel with seep hoses and herbs up by the kitchen.
