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 species catalog holds the care facts, and each researched fact is cited to the source that published it. 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.
Researched species data is cited to the organizations that published it, not scraped from the open web. Older data is labelled as not yet cited.
The engine's job is to combine your plant's record with its species' facts — and explain that combination clearly. It never fills gaps with guesses.
Every piece of advice traces back to what it rests on: the catalog, your plant's own care log and, for an outdoor plant, the local forecast. Each cited fact names its source, and anything not yet cited says so. No black box, no guessing.
The reference that shaped PlantAdvocate isn't another app — it's the way botanical gardens maintain their collections: a rigorous, authoritative species record paired with a living inventory of every specimen. PlantAdvocate brings that same discipline to your windowsill and your garden.
PlantAdvocate is independent. The organizations it cites have not reviewed or endorsed it.
Species names follow the accepted names used by the same extension services and botanical gardens the care facts come from — not advice scraped from the open web.
Each researched light, water, humidity, soil and toxicity value carries a citation to the page that published it. Anything not yet cited is labelled that way, and the check schedules, which PlantAdvocate wrote for 129 common plants, are not cited.
Your plants live in named growing areas with a full history — a living inventory, kept the way a real collection is.
