Antonio De Gannes gave a very informative lecture on growing Dendrobiums,
which is the second largest group of orchids with over 1200 species. He
advised that selecting plants to grow should be based on the parentage
of particular plant hybrids with emphasis on selecting those with suitable
intermediate to hot growing temperatures and elevation where they are
found in the wild. We should select plants with warm growing parents and
found at sea level.
He grows his dendrobiums in bright light with good air movement. Do not
water plants after 4 pm as this promotes fungal problems. His potting
media is broken red clay blocks and charcoal. He prefers to stay away
from using coconut shell as it breaks down after 1 - 1.5 years at which
point you need to re-pot on time or you can lose your plant. Two key indicators
that your dendrobiums are doing well are each sequential growth being
larger and green root tips. His fertilizer of choice is Nutrex 20-20-20
at ¼- ½ tea spoon per gallon twice per week, applied during
the cooler parts of the day.
The monthly show bench was presented by Mark Robinson, one of our very
knowledgeable student judges.

Cattleyas can be divided into two basic groups based on their number of
leaves on the pseudobulb: unifoliate and bifoliate.
Unifoliate cattleyas (labiata, mossiae, percivaliana) have one leaf per
pseudobulb. Generally quite easy to grow as long as potted while roots
are active, which is generally right after they have flowered. Some types
such as Cattleya labiata and Cattleya trianaei form sheaths and then rest.
The sheaths may begin to turn yellow and die, at which time, if they are
not carefully removed, the flowers buds may rot.
Bifoliate cattleyas (amethystoglossa, bicolor, guttata) have two or more
leaves per pseudobulb. These are very sensitive to potting when not actively
rooting, which must be determined for each species individually. Plants
can be quite large and subject to breakage of the rapidly growing pseudobulbs,
hence good idea to stake psuedobulbs. Many of these produce waxy textured
flowers and spotted flowers.
