I've had my Spathiphyllum wallisii for three years now, and I finally figured out why it kept drooping despite consistent watering. Turns out mine was rootbound in that nursery pot—once I moved it to something larger, the recovery was almost overnight. It's sitting on my bathroom shelf now where the humidity is naturally higher, and the glossy leaves have never looked better. Has anyone else found that these plants are just happier with a bit more root space than you'd initially expect?
