Winter can humble even the most confident plant parents. You can have a windowsill full of so‑called “unkillable” houseplants—those hardy, forgiving green companions that supposedly thrive on neglect—and still watch them wilt, crisp, yellow, or drop leaves like they’re auditioning for a dramatic role.
It’s not your imagination, and it’s definitely not a personal failure. Winter is simply a different world for indoor plants, and many of the conditions they rely on during the rest of the year vanish almost overnight. The good news is that once you understand what’s actually happening, you can turn things around faster than you’d think.
