Lower plant can separate pup now. The QV I would wait until they are a little larger then cut them off the mother plant, let heal for a week and pot them up. They should have some roots of their own if you cut the stalk as close to the mother as possible. With QV, I wait until I repot and separate close to the mother plant then. Your plant has been overpotted and won't need repotting for a long time though.

If you really wanted, you could cut off the QV pups now and they would probably survive but personally I would leave them to grow larger first.

I have A. ferdinandi regis that pups. First time it did, I separated 2 small pups approx. size of your QV and of 2, only 1 made it. I wait now until they are bigger. I have now 3 separate plants and 2 small pups still with mother. Just my experience...

Most of my pups are really close to the mother plant. As long as their so far away, leave them on for a few years. If cut too soon they either die or take forever to recover from the cut. I re-pot and remove all pups when ever I can due to wanting a better main plant. Due to the pups being so close to the main stem, Like yours above, I would let then alone.
