I think HH did a progression on a Hornbeam in his 2nd book. This will give me some direction while I wait on a garden of trees that are growing out.Best beginner collector species is Hornbeam. Easy to collect-- just saw off the roots six inches out and under, saw the main trunk three feet up or so, use it as a lever to break the final roots, pick it up, take it home, hose off all the dirt, plant in the smallest container possible in plain old bonsai soil and wait for a few weeks for new buds.
