206 PRACTICAL FLORICULTURE. 



seventy-five degrees by day, with air ; in summer, seventy 

 degrees night, ninety or more degrees by day, with plenty 

 of air and ventilation at night. Cattleya, Lcelia, P/iajus, 

 Calanthe, Cwlogyne and Zygopetalum in winter, fifty- 

 live or sixty degrees at night, seventy degrees with sun 

 by day ; in summer, sixty-five degrees at night, eighty-five 

 degrees by day, with plenty of air. Odontoglossums in 

 winter, fifty-five degrees at night, sixty-five degrees by 

 day ; in summer, as cool as they can be kept. All want 

 abundance of atmospheric moisture night and day. 



5th What period of the year is the growing season ? 

 Phalcenopsis and Vandas grow at all seasons ; Cypripc- 

 diums, Cattleyas and Lcelias in spring ; Calanthe, Cce- 

 logyne, Phajus and Zygopetalums in summer ; when any 

 plant grows in winter (except Odontoglossums} it should 

 be placed in a warm house ; Odontoglossums do best at a 

 temperature of fifty-five to seventy degrees, never hotter, 

 if possible. 



6th What period of the year is the resting season ? 

 Orchids are at rest when the growth is mature. Cattleya 

 triancB, Lcelia anceps and Cypripedium insigne bloom 

 during the resting period, which is from December to 

 January. Phalcenopsis and Vandas grow all the year; 

 during the short dark days of fall and winter less food is 

 given by withholding water. Calanthe, Ccelogyne and 

 Phajus bloom with the maturity of the growth, then 

 lay dormant until spring. 



7th What is the best shading for an Orchid house 

 w hen ground glass is not used ? The Phalcenopsis and 

 Od'mtoglossums I shade with canvas raised eighteen 

 inches above the roof ; all other houses I shade with thin 

 paint, made of turpentine and whiting or white lead ; 

 lay it on the middle of March and brush it off the middle of 

 October ; the plants do well. Ground glass is too dark 

 from October to March for plants ; nothing does well with
