    Default When do Cattleyas form sheaths?

    Is it before the pseudobulb matures? Is it there waiting as the new leaf splits open? Or do they grow in shortly afterward?

    Sheaths always form with the pesudobulb, like the second scenario you mention (waiting as the new leaves split open). I have never had a Catt alliance orchid that formed sheaths after the pseudobulb had matured. Pseudobulbs without sheaths can flower also some Catts will bloom from dry sheaths, but from my observations at least they will never form a sheath once the pseudobulb has completely matured.

    Thanks! I wasn't certain, either, but it makes sense.

    always on the current /newest pseudobulb once conditions are ideal of course....in my experience...shortly after the new leaf almost matures in d case of unifoliate catts and right as new leaves spilt in bifoliate catts
