By popular request of users, there is now the possibility of me the Harvester birch and larch with the jig Demcon MultiTree to plants!
You can always buy as the pallets with 40 seedlings at a garden center! The Damcon MultiTree can be found at Mods - Forestry equipment!
It is a beta version and it could be errors included
