What to do with this stalk of plant

[Maggiethecat]

This plant is starting to look straggly with this leafless stalk.
can I remove it and treat it as cuttings for new plants?

Do you know what sort of plant it is? I've only propagated a house plant from a section of stem with a node and a leaf. I think it can work with just a node but it probably depends on the plant type. You could try coiling it back into the pot but keep it attached to mum. Then, if roots develop, either leave in the original pot to thicken it out or put in a fresh pot. Tbh you've got a long enough shoot to experiment.

Hopefully, someone will be along who can advise you better.

It looks at first glance like Philodendron scandens.

What I would do is layer it - fill a small pot with soil that you keep moist, peg down the end of the stem, just below (nearer the roots) than the leaf, against the soil surface. Wait until there is a very good root system in the new pot, and then cut the new plant away from the old.

This is an offspring plant (think I took cutting from the straggly one!) and a plant check says Golden Pothos (Devil’s Ivy).

Will have a go setting it in soil and see how it goes!

That's a relief! - the variegation. I was thinking it was very sick.

you should be able just to take a cutting, but I always feel layering is safer because the “cutting” stays attached to the parent plant
