ORCHID CARE 

In So. California, keeping orchids happy, healthy and productive depends on environment (temperature, light, air movement), Water quality (generally high in minerals, "hard").  We offer the following general guidelines for successful orchid growing and flowering:     Orchids need to breathe, don't smother them with extraneous decorative moss,  don't seal off their drain holes with plastic wrap, close fitting saucers or other containers.  Keep a good air space all the way around the plant and it's pot.  When watering, use copious amounts of tap water to keep the salts flushed through the root system OR use bottled drinking water in smaller quantities. A good source of additional information:   http://aos.org/aos/,  for The American Orchid Society and their "culture sheets",      http://aos.org/aos/orchids/page01.aspx

  CATTLEYA


These many hued orchids grow best in very bright light and partial sun conditions.  Temperatures between 50 and 85 degrees are ideal.  Water and fertilize regularly, once a week in winter and twice a week in summer. Good air movement and perfect drainage are essential.  Do not let the plants sit on saucers or tables that clog their drain holes.  When the plants are flowering, they can be brought indoors (cool, no direct sun) to enjoy. 



 
  ONCIDINAE

Graceful sprays of subtle fragrance can bloom 2 times per year.  Keep blooming plants in shaded patio or indoors out of direct sun and/or heat.  Water thoroughly every 10 - 14 days.  Be sure to keep bottom of pot elevated to insure the drain holes are open and the roots can breathe.  When blooms have faded and stems are withered, cut the stem off and place plant outside in 50/50 sun/shade, water and fertilize once a week.  The Bright light conditions and regular watering and fertilizing are essential for optimum flowering. 



PHALAENOPSIS


The ideal indoor orchid plant.  Requires a bright, but no direct sun location with moderate temperatures.  Water thoroughly every week  and fertilize.  Keep pot elevated at all times to allow drain holes to breathe.  DO NOT trim off flower stems unless it is completely withered.  More buds and blooms usually form after the first set of flowers have faded.  Phalaenopsis can bloom for several months at a time.  ENJOY!! 


DENDROBIUM

These plants produce sprays of long lasting flowers in many colors and sizes.  We grow and offer for sale only the varieties which grow well in coastal Southern California without excessive leaf drop and pronounced rest periods (when the plant can actually look "dead").  We grow them in as much sunlight as we can give them without burning the foliage and thorough watering (with fertilizer) once a week in winter and 2-3 times per week in summer.  Keep them well drained.

                                                               

  CYMBIDIUM

          Cymbidium plants make a good patio or container plant for your garden.  They grow 
best in plastic containers in a fast draining mix.  In the past, we've used Douglas Fir bark in the "Pathway" size but are switching to Coconut husk chunks in a medium to coarse size.  The Coconut husk chunks do need to be well rinsed with water to wash out any residual salt from processing but seem to be more tolerant of our hard water conditions in Southern California.  Tamp the chunks down firmly with a potting stick or hammer handle so the newly potted plant does not "jiggle".  The cymbidium shown is potted in a 2 gallon nursery container and has five flower spikes this spring.  Cymbidiums are the only orchid that we change fertilizers during the year.  No nitrogen during the summer, approximately Fourth of July until Halloween.  If bloom spikes are left on the plant for weeks/months or the plant kept indoors for extended periods of time,  the cymbidium may take the next year off from blooming to recover.
