CATTLEYAS, MINIATURE: Sheathing Removal From Pseudobulbs It is recommended at repotting time to remove a sheathing if it is brown or dark, to check for fungi or hiding insects as it is a favorite place for them; treat with an insecticide or miticide and clean with a soft toothbrush. F84-229 0
CATTLEYAS, MINIATURE: Sheaths Dry Out Without Buds Reasons are variable and uncertain but C. mossiae hybrids produce flowers after sheaths dry, they flower fall to spring; if the problem is wide-spread the culture may be faulty; other causes may be too much heat or too dry, too much fertilizer or noxious fumes from a heater.

CATTLEYAS, MINIATURE: Under Lights C. trianaei or C. labiata hybrids will not flower if lights are on for more than 14 hours a day so cut the time to 12 hours or less in winter.
