ONCIDIUM (on-SID-ee-um)


Oncidium

LIGHT  60% shade.  Leaves should be a bright apple green.  Dark green foliage indicates too little light and will prohibit flowering.  If growing indoors it should be placed by a bright window.

WATER  Allow to dry almost completely before watering.  This usually means 2 -3  times per week.  Water until the water flows freely from the bottom of the pot.  This should be done 2 – 3 times a few minutes apart.  It is o.k. to wet the foliage.  Look for exposed roots to turn green to know the orchid is thoroughly saturated.

TEMPERATURE Can tolerate our hot summers.  Needs to be protected below 50 degrees.

FERTILIZER Time release fertilizer applied in the Spring.  We recommend Dynamite13-13-13, nine month formulation (apply as directed on the manufacturer’s label).  Liquid fertilizer can be applied weekly at a reduced rate.  If the manufacturer’s directions, say 1 teaspoon, use ½ teaspoon “weekly, weakly”.  It if o.k. to use both time release and liquid fertilizer together.  Reduce fertilizing to every other week during the winter.

REPOT  Use a porous, well draining media, such as a fired clay pellet, coconut chips, charcoal and sponge rock.  Avoid fir bark as it tends to break down in one season with our humidity.  Usually only need to be repotted every 2-3 years.  Spring and Summer are the bests times to repot.  Remember to always use as small a pot as possible and secure the plant tightly.
