Giga....I will wait to repot it, thank you for the advise.
John.....I'm not sure if you saw the pics I posted of the dig...? They are on page 2 of this thread.... Short answer to your question is I did both digging and cutting. I first dug around the trunk to find the flare before basically taking a chainsaw and cutting a 24 dia. slice into the ground about 12 to 15 inches deep. The soil was nice and sandy and didn't have too many rocks in it.....I then dug a channel around so I could cut the tap roots. I hooked up a come-a-long to the hitch of my truck and started pulling the tree over so I could keep cutting it across the bottom....Before I got it all cut the teeth on my chain were shot, it was a wore out chain to start with. I grabbed the wrong spare chain which was too big so I was left to hand cut the rest. I got most of it cut then decided to just pull the tree out of the ground with the truck.
When I got it home I did flat cut it across the bottom but I didn't do a very good job at getting it square.....It sat crooked in the pot so I added dirt and a couple of small pieces of granite to get it to sit straight before wiring it in. I could have fixed the cut but I was wore out and I was afraid to take too much off considering the time of year.....I shouldn't have to do much root work to get it in a pot about 4" shorter than the training pot it's in now.
I know this is no masterpiece but I still think it will be cool as a yard bonsai planted in a large concrete pot sitting on an old stump of some kind, like I have my large collected juniper on now.....I still have to get it in it's concrete pot I made but I decided to wait till spring....But that is a whole nother post.
