My own Monstera Deliciosa has grown a ton, and I needed to thin it out to keep it in its pot! These are stalks off of the same plant. They've been in these pots for over a month now, so they should be past any sensitivity or disruption from having their roots messed with.
I made support poles out of burlap and PVC. The moss poles you often see are very unsustainable; peat moss harvesting destroys sensitive natural areas. This support pole does the same thing a moss pole would, but without messing up wetlands :)
I have two of these propagations I'm selling. Each plant is $20. If both are sold, I'll remove this post as soon as I can; if this post is up, I still have one or both plants.
