Hilfe, ich habe diese ZZ Raven-Stecklinge gefunden und möchte wissen, ob sie eine Überlebenschance haben

I don’t see why not. Stick em in water, give them light, it’s the only wayto find out. ZZs can take a long time to root.

A few pothos cuttings in the same water can help rooting.

Just want to add, in my experience, when the ends get a but mushy while in water, just leave it, it seems to turn mushy before it turns into a rhizome. I’ve had best luck putting them in water and just occasionally adding water but not washing them or completely changing the water or anything.
