In spring 2012, while helping a friend weed her daylily beds, I dug up an eastern red cedar seedling that was maybe six inches tall. Brought it home with me that night and planted it in my yard the next day. It's still here, and it's at least twice as tall as it was when I brought it home. I didn't pay any attention to whether it had a tap root or not, or whether I got all of it or not. It was out of the ground, NOT in a bucket of water, for several hours while I helped my friend weed, and then for the 30 mile drive home. I don't remember doing anything special to help it settle in, but I *do* have a soaker hose around the perimeter of the bed where I planted it.
