I think the original question was about foliar feeding and Junipers, Consider: The reputable bonsaists currently active and referenced by many, almost revered, say that the roots of a Juniper are not so much important as the foliage to a Juniper. Think about it ------?? If the roots are not so important as an abundance of foliage to the health and function of a Juniper, how is it possible that a Juniper does not function through foliar feeding? There is undoubtedly something wrong about all of this, people making policy on two sides of a contrary discussions.
Again this enforces, or at least makes a place for, continuing to examine those things we have to date accepted as graven in stone, or authored by the finger of a god. Chief among them are the concepts of foliar feeding, repotting in spring, summer, and fall, and the ever dreadful and maligned concept of pinching.
