Q.Christmas cactus – what to do with broken woody branch
I just broke off 2 thick branches of 60 year old christmas cactus. I would love to save these, so what do i do for replanting? Do I put branches directly in soil for growing roots? Appreciate any guidance.
The usual and most reliable way to propagate Christmas cactus is by planting the individual green segments as follows:

However, you may be able to get the woody branch to grow by rooting it as described under Cactus Cuttings in the following article:

Rooting hormones can help but aren't always necessary:
