I've had my Epipremnum aureum on a moss pole for about six months now, and I'm finally seeing those split leaves everyone talks about! The aerial roots are gripping nicely, which is satisfying. I'm curious though—does anyone know if the fenestration gets more dramatic as the plant matures, or is it mostly about light? Mine gets bright indirect light, and I'm wondering if I should adjust anything to encourage bigger splits.
