The fastest way to reach us is [email protected]. Include the plant species, the symptom you observed, and any diagnosis URL from plantgrail.com so we can trace the claim to a Grail entry. For course purchases, include the email address used at checkout.
What we can help with
- Corrections to a published diagnosis, article, or confidence score
- Lost access links for Mastery Packs and other digital courses
- Press and dataset questions about the State of Houseplant Health report
- Developer questions about the public JSON API, OpenAPI document, and markdown content negotiation
What we cannot do by email
We cannot inspect a live plant from a photo with the same rigor as a full diagnosis page, and we do not provide emergency veterinary or medical advice. If a plant is collapsing, start with the matching species page in the plant directory, then the problem index, then email us with that URL if the protocol looks wrong.
Response time
Editorial corrections are reviewed as part of the weekly knowledge-base update cycle. Purchase-access issues are treated as support tickets and usually receive a reply within two business days. We do not operate a public walk-in office or a phone hotline; email is the system of record so the conversation can be attached to a Grail or course record.
