In the past few years pots were more often cleanly mulched with bark. Mainly in case of longer cultivations it offers great advantages. Demtec developed a proper working bark mulcher which can be added to your installation. The bark mulcher is equipped with a 800 l container. The layer thickness can easily be set. During mulching the pots are rotated, afterwards the excess bark is removed by vibration. Moreover, we provide our potting machines with a second drill engine to fill pots with a pouring edge so the bark is not on top. This way we prevent bark from coming on the cultivation surface.
