I am completely unskilled with pines but decided to try my hand and picked up a JWP from a local landscape nursery's 50% off end-of-season sale. The tree is massive and so is its pot. I think it is a 25 gallon pot and must weigh about 150-200 lbs. The trunk has a low graft that shows no issues as of yet. The tree is just shy of 6' with a 3 1/2” caliper at its base. It actually has a good amount of low branching which surprisingly have needles close to the trunk and not just at the tips. So my questions, I really want to get this tree more manageable. How much can I reduce the roots when repotting in the spring? I really want to get it out of its nursery muck as much as is safe to do so and reduce the roots so I can pot it in a bit more manageable sized pot. Plenty of plump roots are visible in every drainage hole. I know that bare rooting is not advisable and to keep some of the white beneficial fungus. Also, I want to start to get the tree's height down. From my understanding, it is not wise to remove more than 1/3 of a pine's foliage at a time. How much should I remove, when and when should I make the next large prunning?
