>>17303823I have no garden, but I cope by guerrilla farming as I live semirural. Right now I'm preparing 20 tobacco plants, as a counter-move to the recent increase in price. After that another 50.
Regarding seeds, viability and shelf life is dependent on species. Take for example the coca plant, seeds have to be germinated within 1 month of harvestig or they die. While other plants have seed that's viable for years, even decades.
