Mum, when we had the 'Patch' and the 'Plot', I used to manage a huge Excel spreadsheet with all the bed measurements, what we planted etc, with an intricate plan, all coloured and numbered, printed and copied...
...then I went and changed it all most Saturday mornings, and had to come home and alter it all...
Its a winter thing, and you have to conform, which means you change your mind about every ten minutes!
Wouldn't gardening be boring if we all did it from a single plan starting on January 1st!
Nobody does that!
