How to Propagate Aeonium arboreum ‘Zwartkop’
It is best to grow aeonium arboreum from cuttings. As the stem grows taller, the lower leaves will fall off and leave a bare stem. You can behead the rosette as it grows.
To behead Zwartkop, use a sterile knife or scissors. Allow the main plant’s stem to callous for several days before placing it on well-draining soil. Water whenever the soil has dried out.
