PANG NAM FUI 
A Pothos with rot still comes back if about half its roots are firm. I squeeze them first, cut only what is hollow, then move the plant into a pot sized to what survived rather than to the leaves above it.
Watering a Pothos on a schedule is what kills it. I push a slim dowel to the bottom of the pot and read the damp line instead, because the surface dries days before the mix around the deepest roots does.
A stretched Pothos is really a light problem, and pruning is what finishes it rather than what starts it. I measure the gap between two leaf joints, cut just above a node so the dormant bud below wakes up, then leave the plant alone through a quiet few weeks.
A Pothos cutting roots in water within one to two weeks if it carries a node. I cut just below one, strip the leaf that would sit under the waterline, keep every node submerged, and refresh the jar each week until roots show.
A single pass never settles mealybugs, because the insects sit deep in the leaf joints where a mist cannot reach them. I clear those joints by hand with alcohol on a cotton bud, then hold a fixed repeat until new foliage comes in unmarked.
Two very different problems leave brown spots on this vine, and the boundary of each mark is what separates them. I look at whether the rim is limp and wet or hard and papery, then whether a pale ring around it is still advancing.
A Pothos survives in far less light than it needs to look good, which is why one number never answers this. I work in three bands instead, and I read which one a plant is in from the size of the newest leaves.
Naming a Pothos variety takes four leaf characters read in a fixed order, not a photo match. I work through them one at a time on a settled leaf, and I say so plainly when a plant is still too young to call.
Telling a Pothos from a Philodendron takes one fingertip and about ten seconds. I check the node for aerial roots, then run a thumb down the stalk for the groove, and the answer holds even when no new leaf is opening.
Most of the damage done in a repot comes from washing the roots off and from sizing the new pot up too far. I keep the root ball whole and unrinsed, go one pot size up and no further, then set the plant back in the exact spot it already lived in.
