I've done everything listed above (or pretty close) and probably quite a few yet to be posted.
Today's screw-up? I bought a nice new pair of shohin concave cutters (Kiyozuru $50). While walking into our club workshop meeting tonight (tropical repotting) I tried to carry too much and ended up tipping the bag they were in and dropping them smack onto the pavement. I bet you can guess which part made first contact with the asphalt! Time to get out the diamond file (sigh).
Oh yeah, don't try to repot two medium sized trees in under 30 minutes (today's screw-up #2).
I got a million of em!
