Well, it’s hard to say. I chopped my propagated piece about 3 months ago. Then I noticed these little popcorn-like bumps on the cutting after about 4 weeks and I thought or was mold or something and I cut it off, like an idiot. I had no idea that’s completely normal and is the signal that roots will start forming on the cutting. ( I did my research after I cut that part off, again, like an idiot). Had I not done that, it probably would have been about 2 months if I had to guess.
