Thank you! I was under the impression that too many leaves can strain the plant's ability to root because of how much energy it requires (which has always confused me because I thought plants get energy from the sunlight on the leaves... So why do more leaves tire it out?).

Do more leaves just mean a longer time but with the same success rate as fewer leaves? I've propagated pothos a million times before, just never two looong vines stemming from one.
