    Default Approximate blooming time for cattleyas after sheath appears?

    I have a cattleya that recently (maybe a month or so) produced a sheath. In the last week or two I've seen that there is a little bulge of something in the bottom third of the sheath. Assuming that it will be a bloom or spike, how long does it usually take from the time the sheath appears until something comes out of the sheath? Should I open the sheath or just leave it alone?

    Also, could it be "cattleya season" now (if there is such a thing)? Seems like all my catts and catt hybrids are sending out new growth and a few of them have what look like sheaths. I am in Miami, Florida and all my orchids are outside in more or less full sun. Not sure if this is typical catt behavior or if it just means that our current hot and humid conditions are optimal for catt growth.

    As always, the expert input here is appreciated.

    I have seen it usually takes about 2-3 or some times 4 weeks from noticing the buds in sheath to flowering. My cattleya collection is not very small so leave to experts to chip in if I am wrong

    Sheath to bloom time varies a LOT by variety. Some take months, others weeks. But once you get the bulge of buds in the sheath, you are getting closer. I'm sure that varies a lot too, but for most of mine it seems to be a matter of weeks from a noticeable "bulge" of buds to bloom. Generally you do not slit the sheath, the plant will do so at thew right time. If a sheath seems to be collecting water, or buds seem unable to burstb through, you may slit it.

    Season-wise, catt's come in spring, summer, fall and winter-flowering varieties (and some more than once a year), but it does seem like fall/winter is a big time for catts. Congrats on all your growth!
