Maintenance keeps a finished tree in shape, whereas refinement builds trunk thickness, corrects taper, and forces internal ramification.

To redistribute this energy inward—triggering backbudding and thickening structural areas—you must master two advanced techniques: Sacrificial Branches and Defoliation / Partial Defoliation…
