as much as it has been said already this tree needs to be shortened severely, and then regrown out, i suggest to do it in ground as it will speed the process up.
or at least a grow box.
CD can i ask how long you have been playing around with bonsai? and do you have any experience with growing trees? i only ask as the couple of trees you have posted are kind of a worry, speaking from my experience i was so keen when i first started bonsai to get trees in pots i didnt realise that there was so much more to bonsai than having a tree in a pot, over the past few years this concept changed, i started realising that i needed to get stock that had been grown out (more advanced), and even then most of the trees i aquired had to be chopped down, this also applies to ground grown trees, yamadori.
as you have dug both trees you have posted this is a good thing as you have had some ground growth on the tree, once lifted it shouldnt really have any work on it apart from the roots cleaning them out of old soil and replacing with fresh. then if necessary top growth taken to equal out the impact of the loss of roots. then a rest period is required as the tree has gone through a lot of stress, which brings me to this question, has the two trees you posted had any of this?
the good thing is they are hardy trees to lift from the ground. once the trees have had there rest period and have started growing strong which can sometimes take 1-2 seasons of growing.
if you could chop down while in the ground to induce taper that will make the process a lot quicker, but bonsai isnt something that can really be done fast.
my advice to you is if you can join a club and learn as much as you can from people, get books and read, learn how to look after the trees as if you cant keep a tree alive then bonsai will be hard, people spend lifetimes looking after trees and growing on just for the next generation after them to work on.
im not having a crack at ya mate, your enthusiasm is great, i just think you need to start considering the trees you have dug and how they will go in these tiny pots. it does concern me is all.
keep the enthusiasm mate, keep the excitement its a good thing, you will learn every day with this art and it is very rewarding, i have been in bonsai for 5 years and i can gaurantee i will be into it for the rest of my natural life. it has taken me up to now to really appreciate the how long trees take to get to a certain stage, and the trees i had in pots 5 years ago are basically all out of pots now and in grow boxes as i dont have ground to grow in.
keep it green mate
