I use cinnamon routinely when dividing orchids or treating any wound on my plants. I use rooting hormone when rooting plumeria and air-layering plants, but because I use a really expensive rooting hormone and one that is mixed at the time of use, I use cinnamon much more often.
I haven't watched any of the videos showing cutting the tap-root. All my plants are growing in 4" clay pots and they don't really seem to have a tap-root yet. Mine were all germinated in June, 2015, and probably potted up individually in July/August. At what age is the tap-root normally cut?
