Do you have phals that never seem to bloom? Some people already know how to get 'em to bloom. What do you do?
Phalaenopsis orchids originate from the area of the Philippines. They are prompted to bloom by the natural cycles of the seasonal monsoons. We can simulate the effects of these monsoons. It is easiest do this in the spring and fall when the night time low temperatures are about 55 degrees and daytime temp is about 70 (A daytime temp above 80 inhibits flowers.). What we actually need is a 15 to 20 degree drop from day to night. So if the Phal blooms twice a year lasting 2 to 4 months... well, thats beautiful!
p.s. At long last I'm going to Machu Picchu and Ecuador in November!
I'll be posting a 'lil photo blog during those two weeks.
Oh those temperature conditions are rare in the Philippines, we usually have day temperatures of 90 and drops to about 80 at night. Phals here bloom better only on the highlands or mountain areas like Tagaytay or Baguio.
Although I have one plant which hopefully will re bloom during December when night temps may go down to 70.
