I have a potted White Pine that's about 6' tall and has been in the pot longer than I want to confess to. What should I do to give it the best chance to survive in the ground?
Excellent article. The only thing I would add is, especially in clay soils, dig a square hole, not a round one. Roots follow the path of least resistance, and a square hole actually gives them a point to punch into the native soil, whereas a round hole can encourage them to just circle around.
