    Default Stanhopea oculata backbulbs

    On our society meeting last Saturday, I received these two Stanhopea oculata back bulbs. I have absolutely no idea what to do with them. Please help me getting these to produce new growths and new roots. Until I get help from you I've put them in loose sphagnum so they have some humidity. Thanks for your help.

    I think you're on the right track. When I have tried to start back-bulbs of other genera, I use perlite in something of a semi-hydro setup. The finer-grade material keeps a lot of contact area with the plant tissues, but is still very open and airy - even more so than the sphagnum.

    Hi,

    Would suggest the following steps

    1. Being an outside plant, I would suggest fungicide treatment. Soak it for about 15 minutes in a systematic fungicide. I use 2g per liter of bavistin (Carbendazim 50%)
    2. Soak the pseudo bulbs in seaweed extract or KLN for 15 minutes to promote root growth. I use about 3ml per liter
    3. take a plastic bag and add some moistened sphagnum moss in the bottom and then add the pseudo bulbs and puff in air as you would do with a balloon and quickly close it with a twine.
    4. leave it in a place that can receive indirect bright light...not direct as it would cook the plant.
    5. observe in 2 weeks time and may be repeat moistening the sphag and repack the plastic bag.
    6. should produce roots and new shoots in 4-5 weeks time or longer.
