I was given a few pine saplings a few weeks ago as a birthday present from someone who knows I have an interest in bonsai. I've never grown them before, though, so I'm kind of at a loss for what to do!
All 3 are about 10 inches tall, plus the roots, and I've got all 3 currently in a large plastic pot, about 12 inches in diameter, and about 8 inches of soil. Some metal skewers and some unfolded paper clips are currently serving to keep them perfectly upright, as planting them about 3-4 inches in the soil still left them leaning a little. I watered them once when I potted them, and since then I've left them outside on my covered deck, moving them out from underneath the roof when it rains so they get watered whenever regular trees would get watered. Recently it has started to get very cold, and on nights that threaten frost, I'll pull them inside to an unheated stairwell. Despite my best efforts, though, they're all starting to wilt!
