Robertson County, near Springfield. Dark fired tobacco required smoke curing in the barns. Steamed plantbeds in Feb. while we were in the barn stripping and grading for market. Crop overlapped.
Plants were started about the same time.
Funny thing about ND, I should have started my plants in Feb, but didn't until March (indoors--waaay to cold outside), planted the second week of June, (after the chance of a late frost), and with the longer days at this latitude (5AM to 11:30 PM) almost got them to maturity. Only had aphids to contend with, no tobacco worms here.
I think I'll try again next year.
