root growth looks pretty good. i would separate now, but i have to do a big trunk chop, so i was thinking February. i don't know how it'll respond to a chop in fall instead of spring and if it'll backbud and push shoots or not.
hard chopped and pulled from the woods while it's still cold. i read dogwood bleeds, so avoid big spring and summer chops. it had a nice amout of roots. i let all the coco/perlite fall off without washing or cutting the roots and potted up.
i went to pick some moss and other stuff from the woods off the bark and noticed new buds. in the woods, i noticed all the dogwoods that ended up exposed to full sun because their shade had died had bark loss, die back and death.
