No. 912—Vanda Waipuna 
VANDA HYBRIDS 
Among the most beautiful of all Orchids. They 
belong in every collection. Reports we have 
from our customers indicate they produce more 
flowers per year than any other genus. 
Culture: Strap-leaf Vandas are of easy culture, 
including the temperate-zone glasshouses. They 
are not to be confused with some of the old 
species that were very large plants and flowered 
infrequently. The new hybrids are compact and 
flower almost continuously. Temperatures 
should be from 58 degrees F at night to 80 
degrees F during the day. Higher day temper- 
atures will not harm them if humidity is main- 
tained. They require as much light as you can 
give them without foliage burn. Obviously, such 
light intensity will vary from region to region. 
They are heavy feeders and should be fertilized 
regularly. Any good complete nutrient solution 
recommended for orchids will do. They like 
light, buoyant air but should have at least 60 
70% humidity. Potting can be done in either 
pots or slatted baskets. Use osmunda of hard- 
fibre type in pieces the size of an orange, OT 
chunks of tree fern. Interspace with equal-sized 
pieces of charcoal. Do not pot hard. They must 
have complete drainage. They want to be 
watered frequently but to dry quickly. Obvious- 
ly, hard potting is not conducive to this. 
In tropical regions where the temperature does 
not fall below 50 degrees F, these plants make 
excellent garden subjects. Give full morning 
sun, 50% shade in the afternoon. Fertilize 
frequently and water daily. Pot as described 
for temperate regions. 
Soft rot or crown rot is sometimes a problem. 
This is easily controlled by the use of Manzate, 
one tablespoon per gallon of water, applied 
thoroughly once a week over the entire plant. 
For leaf spots use Dowicide A spray. 
All of our plants are grown hard. Their vigor 
is unsurpassed. All are ready to shift to the 
next size pot when shipped. Vandas benefit by 
oversizing, therefore be liberal in selecting the 
pot size. 
If you haven't tried a Vanda hybrid, do so now! 
They are sure to give you much pleasure.
