Well, after a lot of indecision, I finally put in the home gardens today. Without my garden companion, all that I am likely to manage is the roughly 1800 square feet of the home gardens, and the 100 square foot garlic bed in the rural garden. I started most of the beans & cucurbits in pots on the 17th, to speed up germination & guarantee a good stand; many are already coming up. My brother - who has been calling or visiting me daily since DW passed - spent the day helping me prep & plant the gardens. All direct seeding is done, and spaces are already marked for transplants as they become ready.
The plans had to be revised, to triage what was most in need of renewal, and to accommodate more food production vs. seed production. Only a few purchased peppers & tomatoes (since I was unable to start any this year) and no cool-weather or long-DTM crops. That left room for 17 beans of various species, 8 soybeans, Painted Mountain corn, chard, some potato onions from seed (via the Experimental Farm Network), okra, bitter melon, luffa, cucumber, zucchini, and some of the Little Greenseed pumpkins. Tomorrow I will finish putting up the fence, then start putting in the transplants.
So... without my DW's unfailing help, it appears unlikely that I will be able to maintain my seed collection in its current size. I will clean out a chest freezer to dedicate it for seed storage, and begin packaging & transferring as much as will fit. Hopefully I can still maintain much of the collection, on a reduced renewal schedule... but a lot of commercial varieties (or even widely-grown heirlooms) will likely be dropped, so I can focus on those most in need of preservation. I'll post a list when I know which varieties will be dropped, and offer seed to anyone interested.
