I have a Dendrobium spectabile which I received last year. It is of blooming size and looks to have bloomed many times previously. It has not bloomed for me - yet. Anyway, it has started a new cane - which I was really chuffed about - and I have noticed that there is happy sap on it at the tip. Does this means anything significant or do all canes produce sap at this stage of development? What I am really wondering is whether or not it is a pre cursor to a spike being in the making.
