The Field Key · A Field Manual Tool

What's wrong with my plant?

Start here. Answer what you can actually see, and this key walks you down a botanist's decision path to a real, sourced answer. No photo to upload, no black box guessing on your behalf.

This is a thinking tool, not a verdict machine. A plant can have more than one thing wrong at once, and some problems look alike. The key shows its reasoning at every step and tells you when it's time to stop guessing and get a real diagnosis.

The Field Key is editorial, not commercial. It diagnoses and teaches. Every answer carries its sources, and where a full Field Manual dossier exists, the key sends you straight to it. Built and maintained by The Planters' Guild.
