Q.Why Are My Root Nodes Rotting When I Try To Propagate Njoy Pothos?
I’ve successfully water propagated a variety of my plants, especially Philodendrons and Pothos, but this particular Pothos continually rots during water propagation.

They should root easily in water or soil. Are you changing the water every couple of days? Bacteria builds up if the water is not changed.
Try just dipping the tips in rooting hormone and inserting in a container of moist potting soil (or half peat moss and half perlite). You can cover the pot and cutting with plastic to create a greenhouse effect.
