I am selling plants, mostly herbs but some edibles too. To broaden my range I want to offer some potted Christmas trees. I am in the Southern hemisphere so there is no problem bringing the tree from the cold into the heated room. We are in cool mountain climate, maybe zone 8. Which conifers do you recommend? Were do I get trees seeds? Or is it better to take cuttings (I never did this with conifers) It would be cool to sell the tree in a really nice pot, maybe I should make hypertufa pots or do that jointly with a potter. How long do the trees take to a sellable size?
