Rlc Cattleya Nakornchaisri Red ... when will new root growth begin?

[Louis_W]

I don't have this Cattleya but I do have a few helpful resources.

The first is orchidroots.com where I learned that Cattleya Nakornchaisri Red has TWENTY THREE species in its ancestry. That's nuts! That makes it hard to to guess which species it will be most likely to act like. Since it's 50% C. dowiana you might assume it will be like that one (it roots after blooming on a mature cane, possibly after the next growth starts)

My second resource is this chart that lists all the cattleya species and when they root. (I attached that file below).(credit: William Rogerson and Sue Bottom)

With all that said, the best way is to pay attention to the plant and repot it when you see roots starting to emerge. Its foolproof.

Good luck!
