s are fairly easy to grow and bloom. Most will do well even sitting on a sunny windowsill. You should provide temperatures of 65 to 75 o
F degrees (18C-21 o
C) during the day and 55 to 60 degrees o
F (13C-16 o
C) at night.
Supply plenty of humidity (50% to 70%) during their active growth period, which is when they are growing new pseudobulbs and starting to produce their new inflorescence. They have large flat pseudobulbs with two or three large leaves.
The inflorescence are produced from the sheaths at the base of each new pseudobulb. Keep moist but not wet, do not let them dry out during their growing season, which differs according to the species, or hybrid.
They love good air movement
so I recommend you use a small fan
to circulate the air. After the Brassia
's pseudobulbs mature (quit growing), let the plant "rest" for about 2 weeks by reducing water the frequency of watering.
At this time do not apply fertilizer
, and lower the day and night temperatures by 10 to 15 degrees. Your Brassia
s should be mounted on cork bark
or potted using a mixture of medium-grade potting mix
, 1 part perlite, 1 part coarse peat moss
and 1 part charcoal
Propagate by division keeping at least three to four pseudobulbs per division. Keep in mind many species of Brassia
s can grow to very large size (3 to 5 feet tall), so before you buy, make sure you have the room for them.
