Well, first; how old is the plant in question? Some Catts need to be up to 7
or so years old in order to start flowering. Is this a hybrid or a species
orchid? If it is a hybrid once it starts to bloom it may do so up to 3 times
a year. Before your question can be effectively answerd you need to supply
the above info and also your growing conditions.
Catts in general like to drop to about 60 degrees at night. Also if you are
feeding year round stop. You should only be feeding when the plant is issuing
new growths or flower buds. After a growth spurt they need to be cut back on
water and also feeding.
This is the best i can do for now. Supply more info and i may beable to help
further.
