I have grown my 30yr Norfolk Island Pine from very young, and it has been repotted a number of times over the years ... remaining in my bay window with west/north/east daylight exposure. As it outgrew its space, two years ago I cut accross the trunk below the branches, and three trees have sprouted into a 4ft tall tree w/1ft roots. Question: As it is once again outgrowing the space I have, I want to plant it in the ground. Understandably, the roots may be somewhat comprimised, although they looked workable when last repotte (15" pot). What are your suggestions for a successful transition from inside pot to outside ground?
