Good idea, Rob. I did the same.
Re tobacco, I started a whole bunch indoors back in February in a nice flat, got good germination, put it outside, and the chipmunks dug it all up and planted nuts in the pot. The only plants that survived were those seeds I randomly scattered around other plants I had indoors for the winter. I replanted the flat, but it is now far behind those randoms.
However, I also got sprouts coming up here and there in the gardens where I grew it last year. So I just clean up the weeds around the sprouts and let them go. Volunteer tobacco!
Interesting to me, the sprouts did NOT come up in the nice, soft rich areas. They seem to like the garden ends and edges where the tractor wheels packed the clay hard. Will definitely try that next year on purpose and see what happens.
