i was going to put the following in a "crop rotation" thread but searching turned up scattered mentions but not a comprehensive thread. So I'll start this one and I hope everyone will join in with your experiences and plans
I received an email notice that the "seed" garlic I ordered is being shipped so it's time to finalize plans for where to plant them. This is also when I formulate crop rotation plans for next year.
A while back when I looked into crop rotation and succession, someone who gardens year-round in Ecuador shared her basic core rotation schedule. I drew a diagram of it framed in black with black font, then drew up a large complex diagram, surrounding the core schedule with my garden beds and color coding the crops according to planting/growing seasons -- current year fall/winter (blue), next year spring (yellow green), then summer (yellow orange). The diagrams are so huge I can't see the whole thing unless I look at the PDF file, but here are a couple of screen shots.
I don't follow these strictly, I'm still working on succession schemes within the growing season that intersperses with the main season block rotations of tomatoes --> cucurbits --> corn and back to tomatoes. These include the previous fall to next summer garlic, early spring peas and onions, greens and brassicas, summer beans and edamame, and fall brassicas, greens, and peas.
I'll try to describe more individual examples and details later.
