Dendrobium Culture

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.

Members' Choice Plant
Hazra Maraj won the Members' Choice for August with her beautifully flowered Catasetum (Ctsm.) Memoria Vera Mc Millan 'Little Shaffina' AM/AOS 2007. This plant is a locally bred hybrid, bred by Carlyle McMillan and named after his mother in 1997. His hybrid was first awarded by the American Orchid Society in 1999, with a First Class Certificate (FCC) of 91 points to the clone Catasetum Memoria VeraMcMillan 'Millenium Queen'. Parent plants of this hybrid are Ctsm. Sandy Gibson, another locally bred hybrid and Ctsm. pileatum.

Cultural Corner

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.
