Species Cattleya Rest Period

[DebsC]

Since what or which orchids need winter rest is being discussed in a post above, I would like to discuss the how's of this subject.

I raise primarily catts and most of them are hybrid, but I do have several species catts that I've read need a winter rest.

The little ones and the teenagers, I treat like any other cattleya during winter. I want them to grow bigger and get strong.

But the blooming size are the ones that trouble me. They don't wait until finished blooming to put out new growths. So my questions are;

Do I begin to withhold water even though they already have new growths up to 2-3 inches tall?

If I do this, will these new growths be stunted?

If I don't give them a winter rest, will they bloom next season?

Why are they putting out new growths so quickly?
