CATTLEYAS, BIFOLIATES: Flower Problems In December and January when most problems arise, the alliance is fussy about conditions necessary to produce good flowers because of the lack of light, etc.; good light, a steady supply of food and a buoyant atmosphere are hard to combine in overcast areas; growth becomes abnormal so additional artificial light and better air conditioning become inevitable. OR80-207 0
CATTLEYAS, BIFOLIATES: Flowers Get Smaller From Year to Year This is not unusual with plants grown in the home or under lights where a change in culture is involved contributing to a loss of vigour or energy; a greenhouse produces better flowers usually. A84-473 0
CATTLEYAS, BIFOLIATES: Hybrids Day length and temperatures necessary to induce buds: those with C. labiata or C. mossiae in their forbears usually flower during short days (fall, winter, spring) and can be controlled to flower twice a year with eight to ten weeks of short days; those with C. gigas forbears flower when the new growths mature and can11 be controlled; night temperatures of 55 to 60 dF favor flowering. A83-698 0

CATTLEYAS, BIFOLIATES: New Growth Turn Black This could indicate starvation from loss of roots or overlong day lengths. A86-274 0
CATTLEYAS, BIFOLIATES: Stems Elongated and Weak A period of overcast days can cause flower stems to lengthen and hang down, expecially in long-stemmed types. A88-280 0
