Editorial policy

Evidence before advice

We prefer current Cooperative Extension, university and government material for planting dates, methods and regional conditions. A source is used only for the geography and question it actually covers.

Original synthesis

We do not republish Extension tables or copy substantial passages. Each guide combines the relevant facts into a new decision flow, attributes the source and links to the original publication.

Writing and review

• The answer appears before background information.
• Conflicting sources are described rather than silently averaged.
• AI may assist drafting and quality checks, but it is not treated as a source.
• Pages require human task review and independent subject review before public launch.

Updates

A page is reviewed when a source changes, a material error is reported or the recommendation model changes. A date changes only for a meaningful review, not merely because the site was rebuilt.
