Dendrobium cuthbertsonii culture

Light:  Dendrobium cuthbertsonii prefers bright filtered light, with good air
circulation.  The leaves should have a slight reddish tinge for optimum
growth and blooming.  1000-1500 footcandles.
Temperature:  The temperature range for Dendrobium cuthbertsonii is 70-80
degrees during the day and 45-55 degrees at night.
Water:  Dendrobium cuthbertsonii likes to be moist at all times with pure water that has a low level of dissolved salts.  Use a 20-20-20 fertilizer at 1/2 strength every two weeks.  Never fertilize a dry plant.
Repotting:  Dendrobium cuthbertsonii should be repotted every year, being careful not to disturb the root system too significantly.  The plants grow well in New Zealand sphagnum moss, fine fir bark, or mounted on cork slabs.  They prefer small or shallow pots.  Particular attention should be paid to keeping the plants clean from old flowers and leaves, especially during the winter months.  Dendrobium cuthbertsonii flowers will last for up to six months, with the plants blooming for up to a year.  It is advisable to remove the flowers in the winter, if the plants have been flowering for more than
8 months.  This will allow the plant to recuperate and flower the following season.

Australian Dendrobiums culture

Light:  Very bright light, but no direct sun.  Leaves should be light green in color, or have a reddish tinge to them.  2000-3000 footcandles.
Temperature:  Dendrobium kingianum and many of the Australian Dendrobium hybrids will tolerate a wide range of temperatures and grow best outdoors in coastal and central California.  Ideal daytime temperature is 75-85, but the plants will tolerate temperatures up to 100 degrees.  Night temperatures can go as low as 32 degrees.  From November through February, the plants will flower best if the temperatures are allowed to drop into the 30s and 40s.
Water:  During the growing season (March through October), the plants like
plenty of water, and should be kept somewhat moist.  From November until       January/February, the plants should be kept very dry between waterings to
encourage bud formation.  Once the spikes and buds appear, resume normal
watering.  Use a 20-20-20 fertilizer every two weeks during the growing season, and not at all in the winter.
Repotting:  Australian Dendrobiums should be repotted every 2-3 years, using either fine fir bark or New Zealand sphagnum moss.  The plants prefer shallow pots and like to be somewhat crowded in the pot.
