I bought both of my vanilla orchids about a year ago (variegated and regular) the variegated one was accidentally decapitated shortly after receiving it and the other one I took a cutting from it for my landlord about december (it rooted and is also growing well). Neither of them branched although both started growing again by growing a new tip and continuing on from where they were cut. Both are currently about ten times longer than when I bought them.

Neither of them branched after being cut. Do vanilla orchids not branch when cut back like many vines? The regular leaf vanilla started getting a new growth like a growth tip in the past couple of weeks about a foot up the vine. Is this where it will fork? Right now it's still small although it is like a growth tip than a regular leaf. I've been thinking about cutting both vines (for cuttings) Should I cut just above this new growth tip or the joint above it or should I wait a bit longer?

Both of these plants are my first attempts at growing vanilla orchids so I'm not sure about their growth characteristics.
