Plnting from pot ok sorta. True transplanting removing from ground and relocating, yeah wait.
Dig the hole you can, but take care of the roots carefully. Better to cut than rip.
I really like my root assain RA18 shovel. Narrow, but deep, and has cutting teeth. Cut the circle, loosen with some water, the npick up what you can. Digging around to get the bottom cut well is good too.
You feel like an iditot when you transplant them by 6 feet. Wanted some room for the solar pool heaters. Just about bow hunt from the living room.
Big around as a 55 gallon drum and 20 or 30 degree angled in, should be enough. Go for more if you can. IF the soil is different than where its now, bring some to blend in with new native stuff. Cut back some of the tree if you feel you dont have much roots.
November planting is way better than spring. Give the roots some time to grow and heal, and the soil to settle.
