Has anyone ever had any luck air layering or ground layering one of these? I bought one a few years ago, which only had three large roots shooting straight down at the base. I was told that it would layer easily, so it’s been in the ground with bands (zip ties) around each of the three roots.It is swelling at the base, but no roots yet. Earlier in the late summer, I made some vertical slits and applied rooting hormone. Still nothing. If people have been successful, I may need to just give it more time, or I could be more aggressive and cut an actual band of bark at the base. This would make it do some thing or die.
