Four widely spaced birch cells have separate bone meal storage, hoppers and dispenser buttons. Grow trees on demand, then chop every trunk and replant by hand.
Each dirt pad holds one birch sapling. A dispenser immediately north of it applies one bone meal per button press, supplied by a north-side hopper and chest. Four independent cells are spaced nine blocks apart, so normal birch canopies remain separate. Floor lights keep the growing spots lit. All space above the saplings is deliberately open; the viewer shows the permanent station and initial saplings, rather than a fabricated fixed tree shape. Players operate the buttons, chop trunks, collect fallen saplings and replant. The single south chest is manual output storage. This is a semi-automatic growing aid, with no automatic wood breaking, replanting or item transport.
