Layering is a fantastic way to make more free plants with very little risk. Propagating a plant through layering usually involves pinning down a branch to make contact with the soil so that the branch can begin forming roots. I’ve used layering to propagate more difficult to root plants like oak leaf hydrangeas. Below you will find a short video I put together on layering a deciduous magnolia (‘Jane’). It took a few months for the magnolia roots to form but as you can see in the video the layering technique was very successful.
The only disadvantage to rooting a plant through layering is that you are limited in the amount of material you can produce. That’s not really a problem if you are just make a plant or two for yourself or a friend.
