PlantAdvocate didn't start as a product. It started with a new house, a garden I wanted to grow, and the surprising difficulty of finding plant care information I could actually trust.
When I bought my first home, it came with something I'd never really had before: a garden, and the responsibility of keeping it alive. I wanted to do it right. What I found instead was a wall of contradictory advice — every source confident, few of them agreeing, and almost none of it specific to the plants I was actually trying to grow or the conditions they were living in.
The information to grow a garden well is out there. It's just scattered across extension bulletins, forum threads, and the little plastic tags stuck in the soil — and it's rarely tied to your plant, your light, your history with it. I built PlantAdvocate so that knowledge finally lives in one place: anchored to a real species database and to the record of each plant you're actually caring for. It's the tool I wish I'd had that first season — care information you can trust, specific to the plant in front of you.
The friendly garden gnome you'll meet throughout PlantAdvocate is the face of that idea — a small, stubborn advocate for the plant that can't speak for itself.

This is the foundation everything else is built on. A curated species database holds the verified care facts. The care engine's only job is to reason over that data and your plant's specific history, then say it in plain language. It never invents a care fact that isn't in the record.
Species data comes from vetted horticultural sources, not scraped from the open web where advice contradicts itself.
The engine's job is to combine your plant's record with verified species facts — and explain that combination clearly. It never fills gaps with guesses.
Every piece of advice can be traced back to a specific fact in the database. No black box, no guessing.
The reference that shaped PlantAdvocate isn't another app — it's the way institutions like the Royal Botanic Gardens, Kew maintain their collections: a rigorous, authoritative species database paired with a living inventory of every specimen. PlantAdvocate brings that same discipline to your windowsill.
Species identity draws on authoritative botanical sources — Kew's Plants of the World Online and the USDA PLANTS Database — not advice scraped from the open web.
Light, water, humidity, soil and toxicity for each species are curated and human-reviewed before they ever reach your plant.
Your plants live in named growing environments with a full history — a living inventory, kept the way a real collection is.
