I finally got my Monstera deliciosa to produce fenestrated leaves after almost a year, and I'm honestly not sure what I did right! I think it was a combination of brighter indirect light and finally stopping myself from moving it around so much. I've heard the fenestration is partly genetic, but I'm curious—did anyone else have to wait a really long time for theirs to start splitting? I'm still learning whether it's patience or technique that makes the difference.
