A large and varied genus of plants with beautiful, showy flowers 
of various hues and pleasing color combinations. Distributed 
throughout the East from Ceylon through India, Burmay Assam, 
Maylasia, parts of China, Japan to the Philippines and Australiae 
The majority are easily grown and are free-flowering with long= 
lasting qualities, especially when a chanse of season occurs or 
when climatic conditions allow for temperature variations during 
their ripening or resting periodss ; 
Divided in two cultural groups - the Nobile and Phalaenopsis sections» 
CULTURE: Generally spealcing, their requirements are periods of 
growth and reste When srowing, a cattleya temperature with plenty 
of humidity, moderate quantities of water, overhead syringing and 
light are reaquirede As the new season's growths are completed; 
start ripenine them off by cutting down on pot watering, contine 
uing the overhead syringing until the flower buds appear, at 
which time increase the watering againe During this ripening 
period it is beneficial to move the plants cooler and lishter if 
possible, This ripening off or artificially changing the seasons 
is of prime importance for best flowering resulve, but should not 
be so severe as to shrivel the bulbs. 
The Dendrobium Phalaenopsis section will do best in cattleya tem- 
peratures with the resting period shorter. 
All of the Nobile section will do well hanging and this is espec= 
ially true through the resting or checking periodse 
PROPOGATION: Dendrobiums are raised from seed and plant stock can 
so be increased by dividing the plants at the rhyzomes. They 
sometimes have a tendency to grow offshoots from the pseudo bulbs 
which, when rooted, may be cut off and potted. Old pseudo bulbs 
can sometimes be cut into sections between the nodes, leaving two 
nodes to each section, and laid horizontally on sphagnum moss or 
Vermiculite, covered over, placed in a warm, moist atmosphere and 
little plantlets will start at the nodes. 
POTTING: Pot in a good, medium grade of Osmunda fibre as small 
as possible, allowing for a two year growth period. For best 
results repot the Nobile section soon after flowering. The Phal- 
aenopsis section should be repotted when the new growth reaches 
a height of 2-3 inches. 
FEEDING: Dendrobiums respond beautifully to feeding and we re- 
commend Wilson's Orchid Fertilizer, a 10-10-10 developed by Dre 
Os We Davidson, Florticulture Department, New Jersey Experiment 
Station at Rutgers University. 
GRAVEL CULTURE: All of the Dendrobiums do very well potted in 
gravel and again we recommend the above Orchid Fertilizer used as 
directed for gravel culturee In gravel potting, use larger sizes 
of pots and a one-quarter inch granite gravela 
We have had an interesting experience in growing Dendrobiums over 
a 12 month period in a Cymbidium house with a high light intensity 
of about 75% total light. We used a light weave green 18 x 1h 
Lumite Horticultural Shade Cloth of a e015 mil. filament with a 
licht transmission factor of close to 75% on the outside of the 
clear glass, with no other shading from March through October s 
This, together with a feeding programs as well as under the bench 
humidity system of our special H-261 nozzle tips; plus acequate 
too and bottom ventilation, resulted in exceptionally fine growth 
and flowering, with some large plants producing over 100 flowers 
measuring up to } inches acrosse At the show of buds we moved 
some into a warmer house and flowered them for Christmas, New Years 
and January. The balance left in the cool house flowered in Feb= 
ruary and Marche In addition to the following listing of flowering 
size plants, we often have smaller plants in established divisions 
or offshoots, a year or two from flowering, the prices and descrip- 
tions of which will be sent upon request. 
Every collection should include some plants of this beautiful and 
showy orchide
