I purchased (saved) a small pot of pine saplings over christmas, one small pot, three saplings. The store had allowed them to dry out completely and I complained about it. I even watered the one I bought before I left the store. Once home I transplanted them in a large enough pot of store bought potting soil and undid their roots so they could properly grow. I'm careful not to overwater but the largest sapling has needles that are drying out all except the very bottom branches, the other two are fine. I first put it into a closed plastic container for a day and it softened again. Once replanted in soil it began to dry out so I put a plastic bag over the plant and it seemed to come round. My house is warm at times because its winter and quite dry, though I do have a humidifier. In reading some posts, I just put them outside. Its a cool day but not cold with a little wind and raining slightly. I'm wondering if the problem isn't humidity. The saplings are not brown at all but their branches do come off easily. I really need help here.
