    Cool help, large catt makes sheaths that turn into leaf

    HELP!! I'm inexperienced but I have a huge catt (i lost the tag to identify). I've had it for about 4 years, it has grown in excess of 30 bulbs. It produces sheaths but they all turn into a leaf making the plant a bifolate I think. How do I get it to bloom?

    I have started to grow Catts not that long ago but I have read about them before growing them. Usually growth but no blooms means not enough light.

    But some Catts are photoperiodic, meaning they will initiate the buds only when the nights last longer than the days, usually in December in sheaths that have appeared sometimes several months before (Cattleya amabilis, guttata, labiata, mendelii, mossiae, percivaliana, schroederae, skinneri and trianei)

    Some others will only initiate the blooms when days get longer around May/June (Cattleya forbesii and Sophronitis purpurata which people consider to be a Catt)

    And some don't care about lenght of days or nights and flower up to 3 times a year provided they get enough light (Cattleya aclandiae, bowringiana, dowiana, harrisoniana, intermedia, leopoldii, luedemanniana, violacea, warneri and warscewiczii)

    It would be interesting to know which one you have.
    That's the extent of my knowledge

    If it is growing that well, you are treating it correct with food and water, but it needs more light. Put it gradually into much stronger light. Some catts can take full morning sun, but i advise you to ease it into the full, bright light over several days so that it adjusts. The number one reason orchids do not bloom is insufficient light.

    I put my orchids outside in the summer underneath a tree and screen material. They are under a large plant light when I bring them in late fall. Some of my smaller catts and paphs will flower but this is a tall 17" catt. I did find the tag under the growth it is BLC Nina de Primavera (BLC Orange nugget x C. Horace). I know I need to divide this monster but wanted to be sure I would not affect the plant when Iit already has sheaths.

    That is going to be a real beauty when you convince it to bloom.
    Remember potting is best done during the growing season and if you wind up with more plants that you want there are a few eager collectors out here willing to negotiate.
