I'm currently growing Eastern White Pine Trees (Pinus strobus), from seed. After cold stratifying the seeds, I placed them on a heat mat & they began to germinate.
I just placed them outside last night. As you can see, they are sitting in the shade, provided by a large tree.
I did this because I was afraid they might get burned by the sun, as they are still small seedlings.
Any tips/suggestions on how many hours I should be giving them direct sunlight? They're currently sitting in the shade, but I would assume that they're still absorbing some rays? I don't know.
All I know is that I don't want them to die. Can someone please help?
