How this encyclopedia works
Practical checks, with sources you can read.
Garden Sage checks its plant notes against horticultural sources and links to them in every guide. The advice starts with what you can inspect in your own garden or container.
A symptom can have several causes. These checks help you narrow them down before choosing a treatment.
Still not sure what’s wrong?
Take a photo and ask what to check.
Choose “Help a struggling plant” when Garden Sage asks what you need. Add a clear photo and say what changed. Your saved care history adds context.
