Most plant sites are built like encyclopedias: look up a species, scroll past everything you don’t need, and hope the one paragraph about your actual symptom is in there somewhere. WhyMyPlant is built the other way around. You start with what you’re actually seeing — yellow leaves, a plant that won’t stop drooping, bugs you can’t identify — and go straight to a ranked list of likely causes and the fix for each one, specific to your plant where we have that depth of content, and general where we don’t yet.
Every tool on this site runs entirely in your browser. The Plant ID tool is a guided visual decision tree, not a photo-upload AI service. The Care Calendar, Toxicity Checker, and Light Calculator all work the same way — no account, no sign-in wall, no data sent anywhere to generate an answer. We built it this way because a plant emergency (a wilting fiddle leaf fig at 11pm) shouldn’t require creating a login first.
We’re also not trying to be exhaustive about every plant that exists. We cover the plants people actually own and search for problems with — currently 145 of them in real depth — rather than padding out a database with thin, templated pages for species nobody is asking about. If a plant isn’t here yet, that’s a deliberate choice, not an oversight.
How It Works
Describe the symptom
Pick what you’re seeing — yellow leaves, drooping, bugs, stalled growth — from the diagnose hub.
Get ranked likely causes
Each guide ranks causes by how likely they are for that symptom — not just a flat list — so you check the most probable one first.
Get the specific fix
Follow the general fix, or jump to your exact plant’s problem page for step-by-step instructions tailored to it.

Frequently Asked Questions
Do I need to create an account to use WhyMyPlant?
No. Every guide, tool, and diagnosis page is free to read and use without signing up. The only optional signup is the email newsletter for plant care tips — it's never required to use the site.
How is this different from a plant encyclopedia or wiki?
Most plant sites are organized around species — you look up "Monstera" and get one long page covering everything. WhyMyPlant is organized around problems first. If your plant's leaves are yellowing, you can go straight to a diagnosis path (symptom → ranked causes → fix) instead of reading an entire care encyclopedia to find the one paragraph that applies to you.
What if I don't know what plant I have?
Use the free Plant ID tool first (a guided visual decision tree, not a photo-upload AI service) to narrow down the likely species, then head to that plant's problem pages or the general /diagnose/ guides, which work even before you've identified the exact plant.
Are the diagnosis guides accurate for every variety of a plant?
The general /diagnose/ guides cover the symptom logic that applies broadly across houseplants, and each links into plant-specific problem pages for the varieties we've researched in depth. Where a specific cultivar has quirks (certain pothos varieties reverting variegation, for example), the plant-specific page is written to reflect that — the general guide gives you the reasoning, the plant page gives you the specifics.
Is any of this AI-generated plant diagnosis from a photo?
No. WhyMyPlant doesn't accept photo uploads or run any live diagnostic API — every tool (Plant ID, Care Calendar, Toxicity Checker, Light Calculator) runs entirely in your browser using decision trees and reference data, and every guide is written content, not a generated response to your specific plant.
