there is a process called air layering ,where you strip back the bark on a limb and put moss around it and wrap that with plastic wrap and tape the ends,eventually the moss will help the branch produce roots there and then you just snip below the rooted part.. i inquired about this due to wanting to clone a rare breed of Japanese maple tree and thus is what i found..
