Collect them with as many fine feeder roots as you can with a fair amount of the soil they were in. Don't collect too late and don't bareroot. Let the tree recover in an oversized pot for at least a year. Make sure you give it good drainage. When happy, lodgepole pines grow very vigorously. Don't mess with it till it has recovered it's vigour. Look at lots of threads from other Canadian collectors who have had success. Searching the forums for old threads works well.
