Pretty easy. All you need is dirt, light, and enough space to accomodate the trunk part of the tree. Just...don't set it up near a lava pool. That tends to end a bit badly in my experience.
Even if you don't find it, you can always just place it there. That's what I did when I did the 404 challenge. And lava will set flammable stuff on fire if it's in close proximity. Without warning.

Well, there's embers popping off of the lava, so what do you expect?
