Indoor Plant Guide

I started writing this guide after watching my best friend kill three perfectly healthy pothos plants following generic advice that didn’t account for our dark Pacific Northwest apartments—so every tip here is rooted in hands-on testing with my 47-plant collection, cross-checked with local horticulturists who understand the quirks of low-light, dry indoor air. I built this site because I know how disheartening it is to trust a tip that lets your favorite plant wilt, so every sourcing decision is geared toward making sure you get advice that works for *your* space, not just a sun-soaked greenhouse. When you see a fact here, you can rest easy knowing it’s been tried by me, vetted by experts who grow plants in the same conditions you do, and shared by a community that’s as invested in your plant’s success as you are.
