I know you can propagate stem plants by cutting off a stem and planting it again. I was wondering if there's a way to do something similar to bulb plants. I looked up images of plants online and I'm 99% sure I have Aponogeton in my tank. Can you split the bulb in half and propagate it? Also, in general what happens if the bulb and the plant are separated, or if part of the bulb breaks off?
