I agree with the planting for next year theory! I live in Ontario and every year I faithfully planted my tomatoes inside in March for planting in May. Until last year when I simply left the garden to feed the birds through the winter months and this spring
...well, I have beef steaks & cherry tomatoes in several different beds! They were also easily transplanted for sharing.
This fall I will simply gather the fruits together where I want them to go next year, cover them with a spadeful manure and see what happens. As for cucumbers...I will try it too, save some seeds
for backup but its worth a shot. I always wash my seeds
and leave them to dry on a paper towel, I just cut the paper towel into squares with 6 or so seeds
in each section.
I wonder if the zuccini would work too?
