Orchids in September

General Growing Tips. The welcome transition to fall is upon us. Once the temperature and humidity mediate, you’ll notice many of your plants putting on a second growth spurt. Reward them by watering a little more frequently with dilute fertilizer. You can expect the emergence of buds on many orchids from the cattleyas, evergreen dendrobiums and vandas to cycnoches, catasetums and miltonias. Select the ideal spot for the plant and place pendulous bloomers atop an inverted pot. Support the inflorescence as it emerges and open the sheath to prevent the accumulation of moisture around the developing buds.

Cattleyas. Despite the shortening days and lowering angle of the sun, you will see a flush of new root tips. Keep water and fertilizer in balance with heat and light. Check plants for potting needs for the last time. Any in dire need should be repotted as there is just enough of the growing season left for plants to establish before the days get short and cold. The spectacular, multiflowered C. bowringiana should be in sheath. Observe the puffy sheath structures often, they may need to be opened at the tip to encourage evaporation of condensation that forms around the buds. C. labiata and its hybrids will begin to flower this month along with the spectacular and fragrant forms of the species C. percivaliana.

Cymbidiums. Through diligent breeding programs, the cymbidium season gets stretched longer and longer. Cym. ensifolium hybrids will bloom first with the winter blooming standard sized hybrids soon to follow. Stake Inflorescences and move plants to a shadier location to help the flowers develop.

Dendrobiums. This is the season for the phalaenopsis and canaliculatum type dendrobiums. The long, arching sprays of flat dark red-purple to white or pink saucer-like blossoms provide weeks of satisfaction. Fertilize with low nitrogen fertilizer for the best flowers. Nobile-type hybrids should continue to be maintained on a nitrogen free fertilizer program. You can start to gradually reduce watering frequency on the winter dormant dendrobiums.



Oncidiums. Of the three popular pansy orchids Miltonia xbluntii, roezlii and spectabilis, the latter is probably the most showy. The reddish purple flowers of Milt. spectabilis var. moreliana usually appear singly and last for weeks.

Paphiopedilums. Standard green-leaved paphiopedilums begin to show their bloom sheaths this month. Late season heat waves can blast these early sheaths, so provide proper cooling and air circulation.

Phalaenopsis. The bulk of this season's growth is being ripened this month. Begin to watch watering more carefully and reduce feeding proportionately with reduced watering needs. Phal. hieroglyphica flowers reliably in the autumn. Its fragrant pale yellow flowers are distinctively marked with well defined brown lines on the sepals and petals. Phal. equestris and Phal. lindenii may also show their best now, the former may be everblooming through spring and the latter will arouse curiosity with its attractively striped lip.

Vandas. This is the principal blooming season for V. sanderiana that is the foundation for large flowered modern vandaceous hybrids. Position plants so the inflorescences will grow out of the leaves toward the light. Help uncooperative types by placing a thin bamboo stick between the emerging inflorescence and the flattened form of the leaves, thereby forcing the raceme outward.

Dr. Martin Motes Notes:
Progress of the Season. July has been exceptionally cool with temperatures rarely topping 90 degrees. This welcome relief to high temperature stress for ourselves and our plants resulted from the over abundant rain we received. With most of our sympodial orchids in full growth mode they are exceptionally vulnerable to fungal infections... read more
Orchids in September. September looms as the only truly dismal month in South Florida. Even without the prospect of the unspeakable 'H' word, September disheartens since it is easily the dampest, dullest month in the year. Although more inches of rain fall in June, more hours of rain occur in the often slow, seemingly endless drizzles of September. Frequently a day or two can pass without so much as a solid hour of truly bright... read entire article

Culture Article by Sue Bottom:
Calcium and Magnesium My understanding of what is and what should be in the fertilizers we use for our orchids has evolved over time. First you learn that the three letters on fertilizer container represent the percentage of nitrogen, phosphorus and potassium present in the fertilizer. Then you get treated to a missive on the nitrogen forms, the nitrate and ammoniacal nitrogen that are available to your plant and the urea nitrogen that is not easily used by your orchid... read more
