I'm sure that there will be refinements, but the calendar is complete as of today. Tomato was last on the list - I'm not growing turnips, and zucchini was filed under "summer squash."
Here are a couple of screenshots (click on images for larger size) for how I've organized my thinking. The first is my veggie list, with the tomato section show, which contains the different vegetables with some of the pertinent information. This information has been gleaned from Step by Step, with some additional help from seed catalogs for timing and spacing.
The second is my garden calendar, showing April through July, with dates for sowing indoors, transplanting, and direct sowing (putting the seeds directly in the garden beds.)
With this framework, I now have a pretty good idea of what I need to do for next year's garden. Of course, I'll continue to learn and adjust my ideas and strategies, but the basics are in place. It feels pretty good.
