I have a large Lobophytum leather that is dropping lobes. A white line appears at the base of a lobe and then the leather slowly tears along the line. It is growing new lobes as fast as it drops them and has even increased in size. The leather is currently 7"x8" but can expand out to 10". Has anyone experienced this in the Lobophytum? When do they stop propagating? And does anyone know what the trigger is? All parameters are stable, no changes.
