    Default HELP - Onc. Jinhbao "Gold" spike dying

    Got the plant as a seedling and it finally put out a spike last month. It was growing nicely until it reach 1 1/2 ft and at the very top of the spike (bloom formation) started to change to a light green color. I knew right away this was bad and within 2-3 days, the whole tip got brown and the spike is slowly turning yellow from the top of the spike downward. Now at the different nodes of the spike with a branching growth, they are beginning to turn yellow starting with the top most node. So the spike is dying from the top going down killing off all my bloom growths at each nodes. I don't think I will get to see any blooms from this spike.

    I think I must have damaged the roots in one or many of my watering cycles. This is so distressing because the bloom of this hybrid is supposed to be as large as 1/2 the size of a human hand with dark red maroon striping. I checked the roots and a few have gone soft, too soft.

    Orchidman Murray, what is your conclusion on this matter ???

    Hi Trung,
    I have had a read and am sorry to here of your plite.
    Lets start with the name ,here is the correct spelling

    Jiuhbao Gold = Shonan X Kaizumic Delight and both parents have s species as the pollen parent.Shonan having marshallianum and Kaizumic Delight having varicosum.


    From what you have said about the roots ,it sounds like it is not dring out between watering and has lost a very large part of its root mass and can not support the flower spikes.
    Another possibilitity is bud blast,or the equivilentas there dont have to be buds on the spike.I had that problen back early July when my plants were frosted.
    I would sugest that you repot the plant as there is still time for the plant to develope some roots before winter.

    Hope these notes are of help.
