Humidity: Natural humidity is usually sufficient. 
Watering: Keep moist, but not dripping wet, at all times. 
Flowering: Flowers early January through late Spring. 
May be displayed indoors when in bloom, at which time 
they stand heat best. 
VANDAS 
Light: Needs more light than most orchids. Some varieties 
grown in full sunlight in Hawaii. 
Temperature: Strictly a warm-growing variety, ideal 
minimum at night is 65° plus. Not recommended for 
in-the-home collections, although a fair degree of suc- 
cess has been attained by some home growers. These 
plants do best in glasshouses. 
Humidity: Same arrangement as for Cattleyas, like even 
more humidity. 
Watering: Should be always moist. Water frequently. 
Flowering: Long lasting sprays appear, sometimes six 
times a year.

Flowering: Each growth will flower as it comes into pe a ee 
maturity, seldom a set season, but heavy winter bloomers. Flowering: Long lasting spikes, flower usually twice a 
year. 
ODONTOGLOSSUMS 
Light: About the same light as for Cattleyas. 
Note correct water level BELOW surface of pebbles. 
Temperature: A cool-growing plant, needing 72° or so 
daytimes, with a drop to 50° or 55° at night. NOT 
RECOMMENDED where climate includes prolonged 
high heat at night. 
Humidity: Same arrangement as for Cattleyas. 
Watering: Water same as for Cattleyas, except during 
semi-dormant season, just after flowering until new 
growth appears, when watering should be decreased 
slightly. 
Flowering: Flowers once a year about the same time 
each year. 
CYMBIDIUMS 
Light: Filtered sunlight. 
Temperature: Same as for Odontoglossums. Grows best 
in cool glasshouse, etc., but may be grown outdoors in 
climates where killing frosts do not occur. Not recom- 
mended for in-the-home culture, or for tropic or semi- 
tropical climates.
