Your garden looks exciting! How do you make a map like you did? that seems very helpful..

I used Smart Gardener. It's a freemium service, and I bought the "square foot gardening layout" addon, which gives more options for how you want plant-spacing to work. Some of those square feet have one plant, some have 16. There's a key I didn't screenshot and post that tells me how many I need of everything to fill the areas I've designated. You can either tell it which way is north and your location (because hemispheres and climates) and then have it generate an arrangement for you, or you can drag things around yourself.

I have no idea why my screenshot taken from the print view (because in edit view it's too big to fit on one page) jogs the grid over half-a-square inside the beds.

Are you going to allow for crop rotation? Or have you just decided what your first rotation looks like?

This is actually my second year in this garden, so this is rotation number 2. Last year, the tomatoes were in the bed that has cucurbits this year. There were cucurbits in there too, but they were all at the bottom end of the bed, so there's some slight movement shifting them to the top. The sweet potatoes were on the bed that's off to the side, last year. This year, that bed's brassicas.

In the fall, I'll add another bed to the bottom end of each row, and that'll give me a 3-year rotation for the column on the left (nightshade, cucurbits + sweet potato, legumes) which is where the permanent trellises go. I don't know what I'll put in the non-trellised beds for rotating, but I will be adding a second bed so the brassicas can move out of that one next year. At worst, this year's brassica bed goes fallow next year. This is my first year planting brassicas.
