At the State Fair this year I was in awe of a miniature version of Arb .My favorite nursery had 5 of them, I bought two. The were about 5 feet tall. I hacked them down to 30 inches and next spring I will repot them. The foliage is tiny and offers great scale... can't wait to get going on them.
First step is to get them in some bonsai soil and straighten out root issues. Next step is to push the foliage back and get it all closer to the trunk. Also some trunk decisions. I might do one as a multi-trunk as that is how you find them naturally.
