What cultural methods do typical

I am wondering what exactly goes on behind the “closed doors” of the cut flower greenhouses, in terms of what they actually do to get their roses to produce the premadonnas they often are.

Sorry, the title of this thread was cut out by the server.

The full title of this thread is meant to read as-

“WHAT CULTURAL METHODS DO TYPICAL CUT FLOWER NURSERIES EMPLOY”

A good read that covers not only roses, but other flowers as well, is Flower Confidential: The Good, the Bad, and the Beautiful in the Business of Flowers amystewart.com
