Shell,

When my catasetums display a spike, I take them inside and place in a
sunny window. A drastic temperature difference may cause bud drop.
Normal range is usually 60 to 80 for most catasetums. I would not apply
a fertilizer right now and would assume that the place from which you
received the plant did so to get it to spike.

I've just recieved a Catasetum Rebecca Northen 'Grapefruit Pink' and it has
a small flower spike on it. How do I make sure it blooms? Anything special
it needs like fertiliser or special lighting?
