SEASONABLE ADVICE ON THE CULTURE OF SPRING-FLOWERING 
CATTLEYAS. 
The Fournal des Orchidées has already at different times given some useful 
information respecting the culture of Cattleyas. We must again insist on a 
point which is of great importance at the present time of year, when the growth 
of the new bulbs is completed. About the middle of September these bulbs 
have generally arrived at their complete development, thanks to an abundance 
of heat and moisture down to that time. Growth being completed, we must 
begin to diminish considerably the amount of humidity, to decrease the tempe- 
rature, and to give plenty of air. The point now is to mature the growths and 
prepare them for a strong and vigorous flowering. We ventilate largely the house 
in which these Cattleyas are grown up to the end of October, and also if the 
fine weather is prolonged far into the month of November. Throughout the winter 
these spring-flowering Cattleyas should be kept in a medium temperature, ran- 
ging from 10° to 15° Centigrade (50° to 59° Fahrenheit), with a corresponding 
amount of humidity. The plants should be lightly watered once or twice a week, 
but only in sufficient quantity to prevent the-bulbs from shrivelling. 
The results of good culture after the manner described will be an abundant 
flowering, and highly coloured flowers. 
Gardeners will also do well to remember that these Cattleyas should not 
now be repotted; when they require it, it should be done just after the flowering 
period. 
The successive use of the stalks and midribs of tobacco (), or some efficient 
substitute, on the hot-water pipes will completely destroy insects in the house, 
and is particularly recommended at this season of the year for Cattleyas and 
other Orchids. 
The Cattleya house should be kept as light as possible during the winter.
