Ok so I am thinking about my plot layout and trying to crop rotate too and I'm having a play with a plot planner online - First draft and not to scale of my real plot  but it gives me a good visual for planning to build on, once I get the hang of the online plot!

Here I am fighting for room for more crops but know that there is more in reality - which is a good thing because I am yet to fit in a whole other lot of crops as well as a pumpkin patch!! 

Perhaps by the time I can actually get there and put a shift in, I will have this nailed....Quite fun playing with it though - vegplotter.com - You cna get a free trial, have a go!
