Q.White Shrunken Areas On Organ Pipe Cutting
I am leaving sections of organ pipe cuttings dry to propagate. It’s been almost 2 weeks and I’ve read where I can take up to two months to properly dry. What’s happening now though is that there are a few sections on the ribs that are training weight and shrinking a little bit, like it’s drying out. Does that mean it’s ready to put in the planting medium? Or a sign of some infection? What should I do? Thanks advance!!

This does appear to be an infection. Most times, this happens from using improperly sanitized pruners. From here, I would dust with a fungicide. Wettable sulfur is my go to for application like this. Unfortunately, I can't see the cut end, so I can't see whether it has calloused, or not. Once the happens, it will be time to plant.
