I've had my Monstera deliciosa for three years now, and I'm finally seeing consistent fenestration on the newer leaves. I think the breakthrough was moving it closer to an east-facing window—not scorching afternoon sun, just steady morning light. The growth is noticeably faster too. Has anyone else found their Monstera took a while to really settle in before the dramatic leaf splits showed up? I'm curious if it was just patience or if something specific triggered the change for you.
